A line in the sand XXV

Paris attacks: UN backs 'all necessary measures' against IS:

The UN Security Council has unanimously adopted a resolution to "redouble" action against Islamic State, following last week's deadly attacks in Paris.
The French-drafted document urges UN members to "take all necessary measures" in the fight against IS.
IS said it carried out the Paris attacks, in which 130 people died.
It also claimed deadly bombings in Lebanon this month, while an IS-linked group said it downed a Russian passenger plane in October.

The UN resolution 2249 also condemns recent attacks in Sousse, Tunisia, and Ankara, Turkey.

Aristotle on body and soul

Aristotle's Theory of Soul:

Aristotle's theory, as it is presented primarily in the De Anima (for a complete account, see Aristotle's Psychology), comes very close to providing a comprehensive, fully developed account of the soul in all its aspects and functions, an account that articulates the ways in which all of the vital functions of all animate organisms are related to the soul. In doing so, the theory comes very close to offering a comprehensive answer to a question that arises from the ordinary Greek notion of soul, namely how precisely it is that the soul, which is agreed to be in some way or other responsible for a variety of things living creatures (especially humans) do and experience, also is the distinguishing mark of the animate. According to Aristotle's theory, a soul is a particular kind of nature, a principle that accounts for change and rest in the particular case of living bodies, i.e. plants, nonhuman animals and human beings. The relation between soul and body, on Aristotle's view, is also an instance of the more general relation between form and matter: thus an ensouled, living body is a particular kind of in-formed matter. Slightly simplifying things by limiting ourselves to the sublunary world (cf. De Anima 2.2, 413a32; 2.3, 415a9), we can describe the theory as furnishing a unified explanatory framework within which all vital functions alike, from metabolism to reasoning, are treated as functions performed by natural organisms of suitable structure and complexity. The soul of an animate organism, in this framework, is nothing other than its system of active abilities to perform the vital functions that organisms of its kind naturally perform, so that when an organism engages in the relevant activities (e.g., nutrition, movement or thought) it does so in virtue of the system of abilities that is its soul.

Given that the soul is, according to Aristotle's theory, a system of abilities possessed and manifested by animate bodies of suitable structure, it is clear that the soul is, according to Aristotle, not itself a body or a corporeal thing. Thus Aristotle agrees with the Phaedo's claim that souls are very different from bodies. Moreover, Aristotle seems to think that all the abilities that are constitutive of the souls of plants, beasts and humans are such that their exercise involves and requires bodily parts and organs. This is obviously so with, for instance, the abilities for movement in respect of place (e.g., by walking or flying), and for sense-perception, which requires sense-organs. Aristotle does not, however, think that there is an organ of thought, and so he also does not think that the exercise of the ability to think involves the use of a bodily part or organ that exists specifically for this use. Nevertheless, he does seem to take the view that the activity of the human intellect always involves some activity of the perceptual apparatus, and hence requires the presence, and proper arrangement, of suitable bodily parts and organs; for he seems to think that sensory impressions [phantasmata] are somehow involved in every occurrent act of thought, at least as far as human beings are concerned (De Anima 3.7, 431a14-7; 3.8, 432a7-10; cf. De Memoria 1, 449b31ff.). If so, Aristotle in fact seems to be committed to the view that, contrary to the Platonic position, even human souls are not capable of existence and (perhaps as importantly) activity apart from the body (cf. De Anima 1.1, 403a3-25, esp. 5-16).

It is noteworthy that Aristotle's theory does not mark off those vital functions that are mental by relating them to the soul in some special way that differs from and goes beyond the way in which vital functions in general are so related. It is certainly not part of Aristotle's theory that the soul is specially and directly responsible for mental functions by performing them on its own, whereas it is less directly responsible for the performance by the living organism of other vital functions such as growth. As this aspect of his theory suggests, Aristotle is confident that once one has a proper understanding of how to explain natural phenomena in general, there is no reason to suppose that mental functions like perception, desire and at least some forms of thinking cannot be explained simply by appealing to the principles in terms of which natural phenomena in general are properly understood and explained (cf. Frede 1992, 97).


It might be thought that since Aristotle's theory treats mental functions and other vital functions exactly alike, it obscures a crucial distinction. This worry, however, turns out to be unjustified. The theory treats mental and other vital functions alike only in that it views both kinds of functions as performed by natural organisms of the right kind of structure and complexity. Viewing mental and other vital functions in this way is perfectly compatible with introducing a distinction between mental and other functions if concerns of some kind or other call for such a distinction. Aristotle is perfectly capable, for instance, of setting aside non-mental vital functions as irrelevant for the purposes of practical philosophy (NE 1.13, 1102b11-12).

Animal navigation turns mount improbable into an inaccessible plateau for Darwinism.

Animal Magnetism Comes to Light
Evolution News & Views November 20, 2015 11:44 AM

Perhaps you saw them in Living Waters: sea turtles navigating alone for thousands of miles in the open sea, then returning to the exact beach where they had hatched; salmon swimming from Canada halfway to Japan, then finding their way back to the mouth of their natal stream.

The only global force available to make long-distance migration possible for sea creatures is the Earth's magnetic field -- something humans cannot sense. A compass can point a hiker north, but it cannot tell her the intensity of the field at any given point. A map can tell her companion where he is, but cannot tell him which bearing to take. Both tools are necessary, and both are available to many animals with input from the magnetic field.

At long last, Chinese investigators recently reported in Nature Materials the putative discovery of the physical basis of the magnetic sense in animals: "A Magnetic Protein Biocompass." If their findings are correct, the capability resides in a rod-shaped complex of iron-rich proteins inside particular cells. The abstract explains:

Here, we report a putative magnetic receptor (Drosophila CG8198, here named MagR) and a multimeric magnetosensing rod-like protein complex, identified by theoretical postulation and genome-wide screening, and validated with cellular, biochemical, structural and biophysical methods. The magnetosensing complex consists of the identified putative magnetoreceptor and known magnetoreception-related photoreceptor cryptochromes (Cry), has the attributes of both Cry- and iron-based systems, and exhibits spontaneous alignment in magnetic fields, including that of the Earth. Such a protein complex may form the basis of magnetoreception in animals, and may lead to applications across multiple fields. [Emphasis added.]

"It's an extraordinary paper," one biochemist remarked in Nature News. It may settle long-standing debates about the source of this incredibly accurate sense. David Cyranoski describes the system as "a biological compass needle: a rod-shaped complex of proteins that can align with Earth's weak magnetic field." The Nature News piece includes a diagram of the proposed magnetic receptor (MagR), looking like a rod of ring-shaped proteins rich in iron surrounded by cryptochromes. The Chinese researchers watched these rods orient themselves to magnetic fields. New Scientist takes us into the lab:

The researchers then identified and isolated this protein complex from pigeons and monarch butterflies.

In the lab, the proteins snapped into alignment in response to a magnetic field. They were so strongly magnetic that they flew up and stuck to the researchers' tools, which contained iron. So the team had to use custom tools made of plastic.

The solution looks intriguing, but Cyranoski writes that other scientists remain skeptical. Controversies have gone on for years about the roles of cryptochromes v. particles of magnetite. New Scientist reviews the history of the debate:

There used to be two competing theories about magnetic sense: some thought it came from iron-binding molecules, others thought it came from a protein called cryptochrome, which senses light and has been linked to magnetic sense in birds.

Xie's group was the first to guess these two were part of the same system, and has now figured out how they fit together.

Some skeptics are not convinced that such small amounts of iron in MagR can respond to magnetic fields. Some want to see the magnets work in vivo. Others doubt that the team's research was free of contamination. At best, this may represent "a major step forward towards unravelling the molecular basis of magnetoreception."

What the articles fail to address is the bigger picture of stimulus and programmed response. A compass is useless without eyes to read it and a brain to interpret it. If MagR is a compass needle, how does the animal sense its orientation and respond appropriately? The response mechanism must be able to discern not only the direction of the needle, but the angle of inclination of the field line at a given point as well as its intensity. Even with all this equipment, the animal must have a map inherited at birth to tell it where to go. Magnetosensation is networked with other senses, such as olfaction, proprioception and biological clocks. Without doubt, years of additional work will be required to put all the pieces together.

It immediately becomes apparent that we have here an astonishing example of convergence:

The biocompass -- whose constituent proteins exist in related forms in other species, including humans -- could explain a long-standing puzzle: how animals such as birds and insects sense magnetism....

Many organisms -- ranging from whales to butterflies, and termites to pigeons -- use Earth's magnetic field to navigate or orient themselves in space.

Animals known to have magnetoreception skills range from worms to mammals, insects to fish, bacteria to reptiles. Cows have been observed to prefer to stand in a north-south direction. Even humans appear to possess these protein complexes, suggesting we could develop the skill to a degree. Don't some people have a keener sense of direction than others?

There is an astonishing range of magnetosensing creatures that are unrelated according to Darwinian theory. Maybe that's why none of the articles tried to explain how this ability evolved. Will they say all these lineages hit upon the same systems independently? Or will they claim that bacterial ancestors developed it, but some descendent lineages lost it? Either answer seems dubious.


Intelligent design, on the other hand, predicts that organisms will be equipped with complex systems that can take advantage of environmental cues and respond with precision. That's exactly what we observe. We see similar equipment in our own remote sensing machines like spacecraft and weather instruments, so we are not surprised to find it in living creatures.

An unmistakable signature III

Denying the Signature: Methodological Naturalism and Materialism-of-the Gaps
Stephen C. Meyer November 21, 2015 6:13 AM

Editor's note: Readers of Evolution News likely know the central thesis of Stephen Meyer's bestseller, Darwin's Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design. Meyer argues that the functional biological information necessary to build the Cambrian animals is best explained by the activity of a designing intelligence, rather than an undirected, materialistic evolutionary process. Most reviews of Darwin's Doubt curiously omitted to address or even to accurately report this central claim. However, a review by philosophers Robert Bishop and Robert O'Connor in Books & Culture was a welcome exception. In this 6-part series, adapted from Debating Darwin's Doubt, edited by ENV's David Klinghoffer, Dr. Meyer responds to their critiques. 

Despite their multi-pronged critique, Robert O'Connor and Robert Bishop offer no evolutionary mechanism as an explanation for the origin of the information necessary to produce novel forms of animal life. Neither do they think it necessary to defend the creative power of the natural selection/random mutation mechanism, even though many leading evolutionary theorists now question its ability to generate fundamental innovation in biological form and/or information. To Bishop and O'Connor, it is enough to affirm that God uses (or could use) the natural selection/mutation process, though, they hasten to add, He necessarily does so without leaving any trace of His handiwork behind. "On the evolutionary creationist account, the work is signed using invisible ink," they aver.

In truth, the "evolutionary creationist" account that Bishop and O'Connor articulate in their review, and that they critique me for not taking seriously enough, has no empirical content beyond neo-Darwinism -- although, of course, it can be accommodated to other versions of evolutionary theory as well. For example, in his BioLogos Forum review of Darwin's Doubt, Bishop (writing solo) acknowledges the incompleteness of the neo-Darwinian mechanism, but affirms, without much elaboration or explanation, that other unspecified evolutionary mechanisms have compensated (or, at least, will eventually compensate) for any deficiencies as part of an "extended synthesis."1

The biological details here seem unimportant to Bishop. What is important to proponents of evolutionary creation (EC) or theistic evolution (TE) such as Bishop and O'Connor is affirming that God works through, and only through, secondary causes. Whether there is presently any such evolutionary process that has demonstrated the capacity to generate functional digital information or biological novelty generally matters less than affirming that some such process will eventually account for the exquisite complexity of living things. However, in expressing this confidence in the inevitable success of some naturalistic explanation, proponents of EC (or TE) commit what one might justly characterize a kind of "materialism of the gaps" fallacy. Indeed, the great virtue of Bishop and O'Connor's Books & Culture review is precisely the way in which it reveals their a priori commitment to finding naturalistic explanations for all events and features of the natural world regardless of what the evidence itself might indicate.

The discovery of digital code, hierarchically-organized information processing systems, and functionally-integrated complex circuits and nano-machinery would in any other realm of experience immediately and properly trigger an awareness of the prior activity of a designing intelligence -- precisely because of what we know from experience about what it takes (i.e., what kind of cause is necessary) to produce such systems. But Bishop and O'Connor seem entirely unmoved by discoveries showing the existence of such informational and integrated complexity in living organisms, not because the existence of functional digital code or the nanotechnology in life is in any way in doubt, but because they have committed themselves to viewing the world as if it were the product of materialistic or naturalistic processes regardless of the evidence. (Of course, they conceptualize those processes as modes of divine action, that is, "secondary causes" in theological parlance, even when those same processes clearly lack the creative capacity necessary to explain the origin of the features of life that are attributed to them.)

Both Bishop and O'Connor are Christian defenders of the principle of "methodological naturalism" -- a principle that specifies that scientists must explain all events by reference to materialistic (non-intelligent) causes whatever the evidence.2 For this reason, their affirmation that God designed the universe, but signed His work in undetectable "invisible ink," should be taken with a grain of salt. True, the "signature" of design in nature can only be seen by those with eyes to see. But an a priori commitment to methodological naturalism ensures that we will never perceive (or at least acknowledge) design in nature whatever the evidence, and it codifies our innate tendency to avert our eyes from what is "clearly seen" -- and from what modern biology has made increasingly clear -- in "the things that are made."3

The Watchtower Society's commentary on biblical guidance re:images.

IMAGE:

Any representation or likeness of a person or thing.—Mt 22:20.

Whereas references to images in the Bible frequently relate to idolatry, this is not always the case. God, in creating man, said first, “Let us make man in our image [or, shadow, semblance], according to our likeness.” (Ge 1:26, 27, ftn) Since God’s Son stated that his Father is “a Spirit,” this rules out any physical likeness between God and man. (Joh 4:24) Rather, man has qualities reflecting, or mirroring, those of his heavenly Maker, qualities that positively distinguish man from the animal creation. (See ADAM No. 1.) Though in the image of his Creator, man was not made to be an object of worship, or veneration.

Even as Adam’s own son Seth (born to him in his imperfection, however) was in Adam’s “likeness, in his image” (Ge 5:3), Adam’s likeness to God originally identified him as God’s earthly son. (Lu 3:38) Despite man’s fall to imperfection, the fact of mankind’s originally having been made in God’s image was cited after the Noachian Flood as the basis for the divine law authorizing humans to serve as executioners in putting murderers to death. (Ge 9:5, 6; see AVENGER OF BLOOD.) In Christian instructions concerning feminine head covering, Christian men were told they ought not to wear such a covering, since the man “is God’s image and glory,” while the woman is man’s glory.—1Co 11:7.

Has Jesus always reflected his Father’s likeness to the same degree?

God’s firstborn Son, who later became the man Jesus, is in his Father’s image. (2Co 4:4) Inasmuch as that Son was obviously the one to whom God spoke in saying, “Let us make man in our image,” this likeness of the Son to his Father, the Creator, existed from when the Son was created. (Ge 1:26; Joh 1:1-3; Col 1:15, 16) When on earth as a perfect man, he reflected his Father’s qualities and personality to the fullest extent possible within human limitations, so he could say that “he that has seen me has seen the Father also.” (Joh 14:9; 5:17, 19, 30, 36; 8:28, 38, 42) This likeness, however, was certainly heightened at the time of Jesus’ resurrection to spirit life and his being granted “all authority . . . in heaven and on the earth” by his Father, Jehovah God. (1Pe 3:18; Mt 28:18) Since God then exalted Jesus to “a superior position,” God’s Son now reflected his Father’s glory to an even greater degree than he had before leaving the heavens to come to earth. (Php 2:9; Heb 2:9) He is now “the exact representation of [God’s] very being.”—Heb 1:2-4.

All anointed members of the Christian congregation are foreordained by God to be “patterned after the image of his Son.” (Ro 8:29) Christ Jesus is their model not only in their life pattern, as they follow in his footsteps and imitate his course and ways, but also in their death and resurrection. (1Pe 2:21-24; 1Co 11:1; Ro 6:5) Having borne the earthly “image of the one made of dust [Adam],” as spirit creatures they thereafter bear “the image of the heavenly one [the last Adam, Christ Jesus].” (1Co 15:45, 49) During their earthly life, they are privileged to “reflect like mirrors the glory of Jehovah” that shines to them from God’s Son, being progressively transformed into the image conveyed by that glory-reflecting Son. (2Co 3:18; 4:6) God thereby creates in them a new personality, one that is a reflection, or image, of his own divine qualities.—Eph 4:24; Col 3:10.

Improper Use of Images. Whereas humans are to imitate and endeavor to mirror the qualities of their heavenly Father and model their lives after his Son, the veneration of physical images in worship is consistently condemned throughout the Scriptures. God’s detestation of such practice was clearly expressed in the Law given to Israel. Not only carved images but the making of the “form” of anything in heaven, on earth, or in the sea as an object of religious worship was prohibited. (Ex 20:4, 5; Le 26:1; Isa 42:8) Such objects might be made of any substance, in any form—wood, metal, stone; carved, cast, hammered, hewn; in the figure of humans, animals, birds, inanimate objects, or just symbolic forms—but none were approved by God for veneration. The making of them was a ‘ruinous act,’ the committing of evil in Jehovah’s eyes, a detestable and offensive thing bringing his curse upon those doing so. (De 4:16-19, 23-25; 27:15; Nu 33:52; Isa 40:19, 20; 44:12, 13; Eze 7:20) The decking of them with gold and silver would not make them less disgusting in God’s sight nor prevent their being defiled and discarded as “mere dirt!”—De 7:5, 25; Isa 30:22.

Such use of images is shown to be inexcusable before God, since it goes contrary to all reason and intelligence and betrays foolish, empty-headed reasoning as well as a refusal to acknowledge obvious facts. (Isa 44:14-20; Jer 10:14; Ro 1:20-23) The images would prove to be of no benefit; giving no knowledge, guidance, or protection; being speechless, helpless, and lifeless, an eventual cause for shame. (Isa 44:9-11; 45:20; 46:5-7; Hab 2:18-20) Jehovah’s prophetic declarations, accurately foretelling future events, thwarted any efforts of the unfaithful Israelites to attribute the outworking of such events to their idolatrous images.—Isa 48:3-7.

Despite God’s clear pronouncements, the Israelites and others foolishly attempted to combine the use of religious images with the worship of the true God, Jehovah. (Ex 32:1-8; 1Ki 12:26-28; 2Ki 17:41; 21:7) A woman in the time of the Judges even sanctified certain silver pieces to Jehovah and then used them in the making of a religious image. (Jg 17:3, 4; 18:14-20, 30, 31) Prior to Jerusalem’s destruction by the Babylonians, detestable religious images had been introduced into the temple area, and one such is described as a “symbol of jealousy,” evidently referring to the incitement of God’s jealousy by giving to an image the praise rightfully belonging to him.—Eze 8:3-12; Ex 20:5.

However, certain objects, formed in the image of plants, flowers, animals, and even cherubs, were made at Jehovah’s command and hence were proper. While serving as symbolic representations in connection with God’s worship, they themselves were given no veneration, or worship, as in the matter of prayer or sacrifice.—See IDOL, IDOLATRY.

Images in the Book of Daniel. In the second year of Nebuchadnezzar’s kingship (evidently counting from the time of his conquest of Jerusalem in 607 B.C.E.), the Babylonian king had a dream, the effect of which greatly disturbed him, producing insomnia. He apparently did not recall the full contents of the dream, for he demanded of his wise men and priests that they reveal both the dream and its interpretation. Despite their boasted ability as revealers of secret things, the Babylonian wise men were unable to fulfill the royal request. This brought upon them the decree of death, and the lives of Daniel and his companions were likewise endangered. By divine help Daniel was able to reveal not only the dream but also its meaning. Daniel’s expression of praise and thanksgiving upon receiving the revelation draws attention to Jehovah God as the Source of wisdom and might and as the one who is “changing times and seasons, removing kings and setting up kings.” (Da 2:1-23) The dream was clearly the result of God’s doing and served to illustrate in a prophetic way God’s irresistible dominion over earth’s affairs.

Nebuchadnezzar’s dream was of an immense image, in human form. The body parts were of metal; from top to bottom, they were made of progressively less valuable but harder metals, beginning with gold and terminating with iron; the feet and toes, however, had clay mixed with the iron. The entire image was crushed to powder by a stone cut out of a mountain, the stone thereafter filling the entire earth.—Da 2:31-35.

What is the meaning of the parts of the dream image seen by Nebuchadnezzar?

The image obviously relates to domination of the earth and Jehovah God’s purpose regarding such domination. This is made clear in Daniel’s inspired interpretation. The golden head represented Nebuchadnezzar, the one who, by divine permission, had gained power as the dominant world ruler and, more importantly, had overthrown the typical kingdom of Judah. However, in saying, “You yourself are the head of gold,” it does not seem that Daniel restricted the head’s significance to Nebuchadnezzar alone. Since the other body parts represented kingdoms, the head evidently represented the dynasty of Babylonian kings from Nebuchadnezzar down till Babylon’s fall in the time of King Nabonidus and his son Belshazzar.—Da 2:37, 38.

The kingdom represented by the silver breasts and arms would therefore be the Medo-Persian power, which overthrew Babylon in 539 B.C.E. It was “inferior” to the Babylonian dynasty but not in the sense of having a smaller area of dominion or of having less strength militarily or economically. Babylon’s superiority may therefore relate to its having been the overthrower of the typical kingdom of God at Jerusalem, a distinction not held by Medo-Persia. The Medo-Persian dynasty of world rulers ended with Darius III (Codommanus), whose forces were thoroughly defeated by Alexander the Macedonian in 331 B.C.E. Greece is thus the power depicted by the image’s belly and thighs of copper.—Da 2:39.

The Grecian, or Hellenic, dominion continued, though in divided form, until it was finally absorbed by the rising power of Rome. The Roman World Power thus appears in the image symbolized by the baser but harder metal, iron, found in the legs of the great image. Rome’s strength to break and crush opposing kingdoms, indicated in the prophecy, is well known in history. (Da 2:40) Yet Rome alone cannot fulfill the requirements of being represented by the image’s legs and feet, for the rule of the Roman Empire did not see the completion of the prophetic dream, namely, the coming of the symbolic stone cut out of the mountain as well as its crushing the entire image and thereafter filling the entire earth.

Thus, the expressions of some Bible commentators are much like those of M. F. Unger, who says: “Nebuchadnezzar’s dream, as unravelled by Daniel, describes the course and end of ‘the times of the Gentiles’ (Luke 21:24; Rev. 16:19); that is, of the Gentile world power to be destroyed at the Second Coming of Christ.” (Unger’s Bible Dictionary, 1965, p. 516) Daniel himself said to Nebuchadnezzar that the dream had to do with “what is to occur in the final part of the days” (Da 2:28), and since the symbolic stone is shown to represent the Kingdom of God, it may be expected that the domination pictured by the iron legs and feet of the image would extend down to the time of the establishment of that Kingdom and till the time it takes action to “crush and put an end to all these kingdoms.”—Da 2:44.

History shows that, although the Roman Empire enjoyed an extension of life in the form of the Holy Roman Empire of the Germanic nation, it eventually gave way to the rising power of its onetime imperial subject, Britain. Because of their close affinity and general unity of action, Britain and the United States today are often referred to as the Anglo-American World Power, the present dominant power in world history.

The mixture of iron and clay in the feet of the great image graphically illustrates the condition due to be manifest in the final expression of political world domination. Clay is elsewhere used metaphorically in the Scriptures to stand for fleshly men, made of the dust of the earth. (Job 10:9; Isa 29:16; Ro 9:20, 21) Daniel’s interpretation thus appears to equate the clay with “the offspring of mankind,” the mixing in of which produces fragility in that which is symbolized by the image’s feet and toes. This points to a weakening and a lack of cohesion in the ironlike strength of the final form of world domination by earthly kingdoms. (Da 2:41-43) The common man would wield greater influence in affairs of government.

The golden image later set up by Nebuchadnezzar on the Plain of Dura is not directly related to the immense image of the dream. In view of its dimensions—60 cubits (27 m; 88 ft) high and only 6 cubits (2.7 m; 8.8 ft) broad (or a ratio of ten to one)—it does not seem likely to have been a statue in human form, unless it had a very high pedestal, one that was higher than the human statue itself. The human form has a ratio of only four to one as to height and breadth. So the image may have been more symbolic in nature, perhaps like the obelisks of ancient Egypt.—Da 3:1.

The Image of the Wild Beast. After a vision of a seven-headed wild beast that rises out of the sea, the apostle John saw the vision of a two-horned beast ascending out of the earth, speaking like a dragon and telling those who dwell on the earth “to make an image to the [seven-headed] wild beast.” (Re 13:1, 2, 11-14) Beasts are consistently used in the Bible as symbols of political governments. The image of the seven-headed wild beast must therefore be some agency reflecting the characteristics and will of the globe-dominating political system represented by the seven-headed wild beast. Logically, it should also have seven heads and ten horns like the wild beast out of the sea that it represents. It is of interest to note, then, that another seven-headed beast, distinct from the wild beast out of the sea, is described at Revelation chapter 17. Its significance, as well as that of both the seven-headed wild beast and the two-horned beast, is considered under BEASTS, SYMBOLIC.


After its first mention in Revelation chapter 13, the image of the beast is regularly referred to along with the wild beast, particularly in connection with the worship of that wild beast and the receiving of its mark. The image of the beast shares in these things.—Re 14:9-11; 15:2; 16:2; 19:20; 20:4; see MARK, II.

Yet more on life's antidarwiwinian bias V

An Inordinate Fondness for Confounding Darwinians
Evolution News & Views August 31, 2012 12:43 PM

Write FAIL by another Darwinian prediction: there's no relationship between the length of a branch on Darwin's "tree of life" and how many leaves it has. Evolutionists find this result of a massive study surprising and disconcerting.

The question is this: Shouldn't groups of organisms that have been evolving the longest have the most species? If neo-Darwinism could make any law-like predictions, this should be it: the inexorable pressure to evolve or perish should lead to the most species in the oldest groups:

the most fundamental expectation in macroevolutionary studies is simply that species richness in extant clades should be correlated with clade age: all things being equal, older clades will have had more time for diversity to accumulate than younger clades.
So say Rabosky, Slater and Alfaro, who have just published the most exhaustive study to date of species richness as a function of time. They examined species counts for 1,397 clades, representing 1.2 million species "for taxa as diverse as ferns, fungi, and flies" (emphasis added throughout). Here's what they expected, as reported in their paper in PLoS Biology:
The most general explanatory variable of all is clade age: clades vary in age, and this age variation should lead to differences in clade diversity, particularly if all clades have identical net rates of species diversification through time. If clade diversity is generally increasing through time, there is a strong theoretical expectation that species richness should be associated with their age (Figure S1). Even if individual clades are characterized by a "balanced" random walk in diversity, such that speciation and extinction rates are exactly equal, we may still observe a positive relationship between age and richness through time if clade diversity is conditioned on survival to the present day (Figure S1). Stochastic models of clade diversification through time consistently suggest that species richness and clade age should be correlated. These expectations differ from patterns observed for extinct clades, presumably because living clades have survived to the present to be observed. The expectation that age and diversity should be correlated does not minimize the importance of evolutionary "key innovations" and other factors as determinants of clade richness. In fact, to the extent that such factors influence net diversification rates, their effects should further accentuate differences in richness attributable to age variation alone.
Well, guess what. They aren't correlated. "Clade Age and Species Richness Are Decoupled Across the Eukaryotic Tree of Life," says he paper's title. "At the largest phylogenetic scales, contemporary patterns of species richness are inconsistent with unbounded diversity increase through time," the researchers found. "These results imply that a fundamentally different interpretative paradigm may be needed in the study of phylogenetic diversity patterns in many groups of organisms." Much to their consternation, they couldn't wiggle out of this result (readers can check the open-access paper for how many ways they tried).
The three biologists certainly are aware of complicating factors that might rule out a neat, clean graph. They know that "Some groups, like beetles and flowering plants, contain nearly incomprehensible species diversity, but the overwhelming majority of groups contain far fewer species." Only one species of tuatara, for example, remains after 200 million years on the planet. Sometimes extinction rate exceeds speciation rate; sometimes the ecological niche puts constraints on the ability to diversify. Or, species counts might be artifacts of our taxonomic system or the habits of collectors. Still, even when correcting for these factors, Rabosky et al. expected some remnant of a law-like trend between clade age and species diversity. Not only was no correlation found at the large scale, it was not found at finer scales either. When they authors examined beetles in more detail, for instance, age and diversity showed an even lower correlation than for the bigger picture.

This failure of expectations left them scrambling. It's important to understand the causes for this decoupling, they point out, because most phylogenetic models rely on the implicit assumption that clades should diversify over time at some kind of predictable evolutionary rate. "If age and richness truly are decoupled, then species richness in clades should not be modeled as the outcome of a simple time-constant diversification process, as is done in the overwhelming majority of evolutionary and biogeographic studies." Note that point: the "overwhelming majority of ... evolutionary studies" is based on an assumption that is demonstrably wrong!

Commentary by Harmon

When faced with contrary data this strong, evolutionists have to be immensely creative in coming up with ways to dodge the implications. Luke J. Harmon, for instance, commenting on this paper in the same issue of PLoS Biology, tries humor. He tinkers with an irrelevant joke by J. B. S. Haldane who, noting the 400,000-some-odd species of Coleoptera, quipped that "God has an inordinate fondness for beetles." Harmon titled his paper, therefore, "An Inordinate Fondness for Eukaryotic Diversity."

The point of his commentary is that this is not really a problem; sure, the study showed that it is "difficult or impossible to predict how many species will be found in a particular clade knowing how long a clade has been diversifying from a common ancestor" -- but one thing evolutionists can take heart about, he assures us: we're slowly becoming ever wiser and more knowledgeable about Darwin's world:

This pattern suggests complex dynamics of speciation and extinction in the history of eukaryotes. Rabosky et al.'s paper represents the latest development in our efforts to understand the Earth's biodiversity at the broadest scales.
Where is the understanding exactly? Evolutionists predicted a trend, and found none. Does labeling the situation "complex " help? Does a drunken sailor's staggering suddenly make sense simply by speaking of it as reflecting a "complex dynamic"?
Harmon praises Rabosky et al. for "the most ambitious study to date" saying, "This provides a remarkably complete view of what we currently know about the species diversity of clades across a huge section of the tree of life." He imagines an escape hatch in the future, saying that their "analysis is not the final chapter" because "the tree of life is still under construction, and the total number of species in some clades is best viewed as an educated guess." Maybe somebody else will find a pattern some day. With more genomes, or with improved species counts, who knows?

"Still, the results in Rabosky et al. are intriguing and will certainly inspire further study, which I expect will be focused on testing more sophisticated mathematical models, beyond the constant-rate birth-death models prevalent today, that might be able to explain patterns in the data." Yes, falsifying evidence is indeed "intriguing." After that, Harmon wanders off into a distracting diversion about another evolutionist's quip, this one by Huxley, who joked about "Santa Rosalia as the patroness of evolutionary studies." Pay no attention; there's no falsification here. Look at this nice shrine!

News Coverage

How did the science news media spin this result? Michael Alfaro, senior author of the paper, works at UCLA, where a press release written by Stuart Wolpert gave the official interpretation for public consumption (for instance, on PhysOrg). "Why evolution has produced 'winners' -- including mammals and many species of birds and fish -- and 'losers' is a major question in evolutionary biology," we're told.

Scientists have often posited that because some animal and plant lineages are much older than others, they have had more time to produce new species (the dearth of crocodiles notwithstanding). This idea -- that time is an important predictor of species number -- underlies many theoretical models used by biologists. However, it fails to explain species numbers across all multi-cellular life on the planet, a team of life scientists reports Aug. 28 in the online journal PLoS Biology, a publication of the Public Library of Science.
"We found no evidence of that," said Michael Alfaro, a UCLA associate professor of ecology and evolutionary biology and senior author of the new study. "When we look across the tree of life, the age of the group tells us almost nothing about how many species we would expect to find. In most groups, it tells us nothing."

Another idea, that some groups are innately better or worse at producing species, similarly fails to explain differences in species number among all of the major living lineages of plants and animals, the life scientists found.

So far, this is a forthright statement of the findings. Wolpert gives significant space to Alfaro's favorite rescue strategy, that of "adaptive zone carrying capacity" -- the notion that speciation will proceed up to the point where an adaptive zone is filled to its carrying capacity, then will stop. "Most of the groups that we studied have hit their limits," Alfaro said. "Ecological limits can explain the data we see." This is, of course, not an explanation but a post-hoc rationalization.
So despite the despairing tone of the paper, Alfaro finds a little light in the darkness: "The ultimate goal in our field is to have a reconstruction of the entire evolutionary history of all species on the planet," he says. "Here we provide a piece of the puzzle. Our study sheds light on the causal factors of biodiversity across the tree of life."

But in the paper, the three authors jointly considered and rejected adaptive zone carrying capacity as a suitable explanation for the data. The idea of adaptive zones is not new; George Gaylord Simpson coined the phrase in 1953. Adaptive zone carrying capacity was one of several "diversity-dependent processes" the authors investigated that might result in the decoupling of time and diversity they found. The explanation would be that "ecological opportunity influences the tempo and mode of species diversification through time."

A fallacy in this explanation, though, is its assumption that carrying capacity is static: "We may not understand the ecological mechanisms underlying 'carrying capacity dynamics, but we must still wrestle with substantial neontological and paleontological evidence for their existence." The dynamics exist, they mean. Organisms have uncanny abilities to break out of the box and enter new niches, or to rebound after mass extinctions; the explanation, therefore, fails when considered in the long term. It certainly does not explain why one species of tuatara survives in the same adaptive zone as hundreds of species of beetles.

The authors would not have left time-richness decoupling as an unsolved problem if any number of explanations they considered were of any help: "we are not presently aware of any non-biological mechanism that can account for this lack of relationship," they conclude. Maybe in the future someone will find a law-like pattern; for now, it's a failed prediction of Darwin's tree of life that may require a "fundamentally different interpretive paradigm," as yet unknown.


Intelligent design theory holds no fixed view on common descent per se, with some in the ID camp being personally skeptical of the idea and other more accepting. Either way, from an ID perspective, there seems no reason to expect species richness to correlate with time. The data fit well with ID predictions, therefore, but represent a strong disconfirmation of neo-Darwinian predictions. Once again, nature seems to have an inordinate fondness for confounding Darwinians.

Yet more on life's antidarwinian bias.IV

Life Is Designed to Fight Darwinism

Evolution News & Views September 26, 2012 10:03 AM 

Life knows all about Darwinism. That's why it is intelligently designed to resist it.

Neo-Darwinian theory teaches that mutations are random, then a process of "selection" chooses which ones to preserve (Darwin himself was bothered by the implicit personification in "natural selection"). Some mutations are random, for sure. No cell can anticipate where a cosmic ray will hit. How, then, can cells regulate mutations, turning on a "low mutation rate phenotype" under stress? In Current Biology, McDonald and team experimented with E. coli response to mutations. Their paper featured these 4 highlights:

The evolution of low mutation rates in mutator-founded populations • Nonmutators do not only evolve due to reduced genetic load compared to mutators; they can invade • Diploidy is found to be closely associated with reduction of the impact of the mutator phenotype • Genomes may influence mutation rates by initiating more high-fidelity replication early in S phase.

The authors believe that mutations are the source of "beneficial adaptive variation," but cannot deny they also produce "deleterious genetic load." When a cell invades a novel environment, it is able to switch on a "mutator phenotype" with a 10- to 100-fold increase in mutation rate. The fact that this "mutator allele" switches on is an indication that there's a functional purpose behind it. It's risky, because mutational load is likely to drive many of the cells extinct.

We find that after ∼6,700 generations, four out of eight experimental mutator lineshad evolved a decreased mutation rate. We provide evidence that theaccumulation of deleterious mutations leads to selection for reduced mutation rate clones in populations of mutators. (Emphasis added.)

The authors did not give any examples of a beneficial mutation. All they proved is that populations tend to "evolve" a decreased mutation rate, thereby cutting off the source of "beneficial adaptive variation" while saving themselves from "deleterious genetic load."

Defensive Block and Tackle

"Researchers demonstrate how 'interfering' RNA can block bacterial evolution" is the headline of anews release from Rockefeller University. As expected, the pro-Darwin press release speaks of "evolutionary tricks" and "instant evolution," but a close reading shows a designed mechanism for surviving under stress:

Bacteria may be simple creatures, but unlike "higher" organisms they have a neat evolutionary trick. When the going gets tough, they can simply pick up and incorporate a loose bit of genetic material from their environment. It's instant evolution, no time-consuming mutations required. This process, known ashorizontal gene transfer, is an important reason why nasty bacteria like pneumococci are often able to evade immune system attacks and antibiotic drugs.

Needless to say, "evolution" without "time-consuming mutations" is not the neo-Darwinian way. By picking up existing genetic information from the environment through horizontal gene transfer, the bacteria give evidence of design for surviving storms of misfortune:

"Transformation is something that bacteria use as a last resort," says Luciano Marraffini, head of Rockefeller's Laboratory of Bacteriology. "In a desperate attempt to stay alive under hostile conditions, they start incorporating whatever genes they can find into their chromosome in the hopes that they can quickly evolve out of trouble."

Michael Behe described in The Edge of Evolution how a cell under stress, like a city under siege, will do whatever it can to survive, throwing whatever is available at the enemy or accepting weapons from allies. If it survives, it has not become something better. It just avoided dying. The ability of a cell to accept or reject existing foreign DNA shows evidence of design for disaster preparedness.

Epistasis and Stasis

Mutating a gene affects other genes. Genes belong to networks that can absorb shocks. That appears to be the message in a PNAS paper about epistasis, or "nonlinear genetic interactions between polymorphic loci." Do epistatic interactions promote speciation -- the kind Darwin needs -- or do they promote canalization, the ability of a genotype to vary and yet still produce the same animal?

Whatever the hope, the researchers found that "Epistasis dominates the genetic architecture ofDrosophila quantitative traits." By comparing two pools of fruit flies, they found a lot of genetic variation that the networks apparently absorbed, because both populations remain fruit flies. "Knowledge of epistatic networks will contribute to our understanding of the genetic basis of evolutionarily and clinically important traits," they said, indicating evolutionists don't have that understanding yet.

Neo-Darwinism: Reality vs. Hype

With these anti-Darwinian processes in mind, let's examine some of the recent claims in the news from the world of science.

Lenski Again

Michigan State University went over the top again in its hype about Lenski's lab with its E. colipopulation that "evolved" the ability to digest citrate. "Evolution is as complicated as 1-2-3" theMSU press release blares. We might ask why his research assistant Zachary Blount is sitting under a pyramid of petri dishes. Maybe he is meditating on new ways to blow the data out of proportion.

Casey Luskin and Michael Behe unmasked this hype last year so there is no need to repeat it, since nothing new is added by the press release.

Gain of function?

A paper claiming to find a "gain of function" was published in Science magazine, announcing, "A Gain-of-Function Polymorphism Controlling Complex Traits and Fitness in Nature." Prasad and team realize the obvious: that neo-Darwinism can't afford to lose money on every sale:

Few studies have identified the genes that underlie complex trait variation in nature and the evolutionary processes that influence these polymorphisms. Most such work has focused on loss-of-function mutations that lead to adaptive phenotypes, likely because novel gain-of-function changes occur infrequently and require persistent natural selection to be maintained in populations. Nonetheless,new functional mechanisms are crucially important for adaptive evolution. To understand the adaptive consequences of complex trait variation, we must establish a direct relationship between genetic polymorphisms and phenotypic traits, and investigate the fitness consequences of this variation in natural environments.

This is amazing: the Darwin Bicentennial was three years ago, but hardly anyone has yet tied genes to fitness! Most of the actual lab work has identified loss of information that allowed organisms to adapt. But evolutionists need to tie genes to fitness gains, they said. It's important. Neo-Darwinism must establish that relationship. Read that paragraph again and let the import of the confession sink in.

That was the build-up to their announcement of a gain-of-function mutation: the ability of a certain plant to ward off pests a little more effectively with a slightly modified chemical defense gene. Again, though, as with the citrate claim, they were talking about an existing polymorphism in one of the populations of similar plants. Despite their pride in showing how a particular gene location "affects plant chemistry and insect resistance, and thus fitness, in a quantitative manner," the fitness gain they came up with was only 1.3%. Whether a subjective notion like "fitness" can be quantified to two significant figures is highly suspect.

What's more, numerous other factors could confuse the conclusion. The populations were separated by many miles, one in Colorado and another in Montana, where ecological differences (weather, type of pests and their ratios) could be more important than the similarities. The researchers' courageous attempts to attribute this slight benefit to modest changes in existing complex pathways is overshadowed by their admission that "few studies have identified the genes that underlie complex trait variation in nature."

Finches Again

Reviving the old icon of Darwin's finches, some evolutionists at Harvard Medical School, publishing in PNAS, peeked into beaks and gleaned genes for insight into evolution. From the abstract, it appears all they found was that finches in the Caribbean and finches on the Galapagos grow bigger beaks in a slightly different order. Darwin's finches develop the prenasal cartilage first, then the premaxillary bone, whereas the Caribbean finches do both at the same time.

"Together, our results demonstrate high flexibility in the relationship between morphology and underlying developmental causes, where different developmental programs can generate identical shapes, and similar developmental programs can pattern different shapes." This appears to be just another case of canalization with not much to speak of in terms of real evolutionary change. In fact, since the beaks of Darwin's finches have been shown to oscillate between big and small depending on the climate, this flexibility in developmental programs (note that word "programs") is arguably a good design feature, providing robustness to perturbations, not a pathway to better things.

Summary

In short, the claims by evolutionists for neo-Darwinian progress are modest at best and unsupported at worst, while evidence mounts that life is designed to resist neo-Darwinian mechanisms in its requirement to survive stress and adapt to change.

@ Kepler438b;Don't call us we'll call you.

Fare Thee Well, Kepler 438b
David Klinghoffer November 19, 2015 11:08 AM



That was fast. Excitement about the "most Earth-like planet ever," the potentially habitable and therefore hypothetically inhabited Kepler 438b, launched in January with an announcement at the American Astronomical Society meeting here in Seattle. Researchers from the Harvard-Smithsonian Center for Astrophysics bore the good news.

From the story in The Guardian:

An alien world that orbits a distant star in the constellation of Lyra may be the most Earth-like planet ever found outside the solar system.

The planet, named Kepler 438b, is slightly larger than Earth and circles an orange dwarf star that bathes it in 40% more heat than our home planet receives from the sun.

The small size of Kepler 438b makes it likely to be a rocky world, while its proximity to its star puts it in the "Goldilocks" or habitable zone where the temperature is just right for liquid water to flow.

A rocky surface and flowing water are two of the most important factors scientists look for when assessing a planet's chances of being hospitable to life.

Kepler 438b, which is 470 light years away, completes an orbit around its star every 35 days, making a year on the planet pass 10 times as fast as on Earth. Small planets are more likely to be rocky than huge ones, and at only 12% larger than our home planet, the odds of Kepler 438b being rocky are about 70%, researchers said.

That's over, it seems, just ten months later. As we learn now, it seems more probable that this "most Earth-like planet [is] uninhabitable due to radiation." From the announcement by scientists at the University of Warwick:

The most Earth-like planet could have been made uninhabitable by vast quantities of radiation, new research led by the University of Warwick has found.

The atmosphere of the planet, Kepler-438b, is thought to have been stripped away as a result of radiation emitted from a superflaring Red Dwarf star, Kepler-438.

Regularly occurring every few hundred days, the superflares are approximately ten times more powerful than those ever recorded on the Sun and equivalent to the same energy as 100 billion megatons of TNT.

While superflares themselves are unlikely to have a significant impact on Kepler-438b's atmosphere, a dangerous phenomenon associated with powerful flares, known as a coronal mass ejection (CME), has the potential to strip away any atmosphere and render it uninhabitable.

The planet Kepler-438b, to date the exoplanet with the highest recorded Earth Similarity Index, is both similar in size and temperature to the Earth but is in closer proximity to the Red Dwarf than the Earth is to the Sun.

I note this with no malice toward the likely sterile and desolate exoplanet. A habitable or, even more so, an inhabited planet elsewhere in the cosmos would be very exciting news. We neither need it nor fear it. If life were seeded across the stars, though that certainly seems not to be the case, it would be neither here nor there for those who recognize the evidence for design in biology and cosmology.


Presumably, life driven by biological information on another planet would call for an inference to design just as it does on Earth. Tell me how the logic would differ because of a transfer of venues across some number of light years? See our video, "The Information Enigma":Materialists, on the other hand, need extraterrestrial life. They need it very badly. Life cannot be uncommon. It must spring up easily. Just add sunshine! For them, the demise of this most hopeful of exoplanets is sorry news.

On Darwinism's broken compass.

Family Size in Affluent Cultures: Another Failed Prediction of Darwinian Theory
David Klinghoffer August 30, 2012 5:08 AM


If natural selection really is the creative driving force behind the evolutionary development of species, you ought to find it programming creatures to maximize the number of their descendants. But this prediction of Darwinian theory is foiled by research newly reported in the Proceedings of the Royal Society B. Scientists in Sweden and the UK studied a cohort of 14,000 Swedes born between 1915 and 1929, plotting the relationship between family size, social and biological success ("Low fertility increases descendant socioeconomic position but reduces long-term fitness in a modern post-industrial society").

I take this subject personally since, with five kids, my wife and I consider ourselves as having a packed house. However, that's only relative to the culture around us -- Seattle -- which competes with San Francisco for the title of America's most childless city. In other places our family would be considered modest in size. My brother-in-law and his wife in Jerusalem, for example, have 18 (eighteen) kids.

The so-called demographic transition describes the way that as societies become more affluent, people have fewer kids. In Seattle, instead of children, people have dogs. The seeming evolutionary anomaly -- as folks find they can afford to support a larger family, they in fact curtail their reproduction -- has traditionally been explained as a longterm strategy of natural selection. You have fewer kids but you can care for them better so that in the long run you in fact ensure the spread of your genes to future generations. It's a tradeoff, quantity for quality.

That rationalization turns out to be wrong. Smaller families and their descendants are wealthier and more successful in social and educational terms. Measured for "descendant reproductive success," though, the strategy is at best a wash and at worst a flat contradiction of what natural selection is supposed to be selecting for.

From the Abstract:

Adaptive accounts of modern low human fertility argue that small family size maximizes the inheritance of socioeconomic resources across generations and may consequently increase long-term fitness. This study explores the long-term impacts of fertility and socioeconomic position (SEP) on multiple dimensions of descendant success in a unique Swedish cohort of 14,000 individuals born during 1915-1929. We show that low fertility and high SEP predict increased descendant socioeconomic success across four generations. Furthermore, these effects are multiplicative, with the greatest benefits of low fertility observed when SEP is high. Low fertility and high SEP do not, however, predict increased descendant reproductive success. Our results are therefore consistent with the idea that modern fertility limitation represents a strategic response to the local costs of rearing socioeconomically competitive offspring, but contradict adaptive models suggesting that it maximizes long-term fitness. This indicates a conflict in modern societies between behaviours promoting socioeconomic versus biological success.
The study's lead author, Anna Goodman of the London School of Hygiene & Tropical Medicine, puts the difficulty for Darwinian theory in these terms:
Under natural selection, you would expect organisms to use their resources to produce more genetic descendants, and so increase their Darwinian fitness. The demographic transition is a puzzle because at first sight it doesn't look like people are doing this. One adaptive explanation for the puzzle is that there exists a quantity-quality trade-off, such that having more children leads to those children being less able to reproduce in turn -- i.e. higher "quantity" leads to lower biological "quality." However our study found this quantity-quality trade off only applied to descendants' socioeconomic success, not their reproductive success.
Given natural selection, you would expect one thing. What you get is the opposite. That's called a failed prediction and Darwinists have a variety of strategies for dealing with those, as Cornelius Hunter writes at Darwin's Predictions:
Evolutionists argue that evolution is a fact, and that we ought to focus on evolution's successful predictions rather than its false predictions. The tendency to seek confirming evidence over contrary evidence is known as confirmation bias. One consequence of confirmation bias can be that confirming evidence is viewed as correct and typical whereas disconfirming evidence is viewed as anomalous and rare. Not surprisingly the confirming evidence is more often retained and documented. Rarely are the many false predictions found in evolution texts. Confirmation bias can hinder scientific research, particularly when researchers believe they know the truth, as do evolutionists. They view the important predictions of evolution as predominantly true. False predictions, on the other hand, are usually not viewed as legitimate falsifications. Instead, these are interpreted, more positively, as open research questions which are yet to be resolved. Indeed, evolutionists often make the remarkable claim that there is no evidence that is contrary to evolution.

Those British and Swedish researchers ought to have a chat with our friend Eugenie Scott of the National Center for Science Education, who advises Darwin advocates to avoid giving the impression that evolutionary theory has any serious weaknesses at all.
