Yet more on why we can't take OOL science seriously

Origin of Life: Top Three Problems with Protocells

Rob Stadler
 
 

The latest video in the Long Story Short series was released this week on YouTube. The video explains how cell membranes in all of life display complexity that cannot be explained by purely natural processes. See my comments from yesterday, “New Animated Video: Cell Membranes by Natural Processes Alone?,” adding some supporting details to the argument. Here’s more.

 

As we uncover layer after layer of the astounding complexity of even the simplest forms of life, the origin-of-life research community increasingly relies upon their trump card: imaginary protocells that supposedly existed long ago and were dramatically simpler than existing life. As the story goes, modern life may indeed be very complex, but protocells used to be much simpler, and there was plenty of time for the complexity to develop.

Protocells conveniently fill the uncomfortably large gap between the simple molecules that can be produced by prebiotic processes and the staggering complexity of all extant life. But there are three major problems with the concept of protocells. These problems are all backed by strong empirical support, in sharp contrast with the concept of protocells.

A Coddling Environment

First, scientists have been working for decades to simplify existing life, trying to arrive at a minimal viable life form by jettisoning anything that is not essential from the simplest extant cells. The success of Craig Venter’s group is well known. Building on their efforts to produce synthetic life (“Synthia” or “Mycoplasma labritorium”) in 2010,1,2 in 2016 they introduced the current record holder for the simplest autonomously reproducing cell (JVCI Syn3.0).3 With a genome of only 473 genes and 520,000 base pairs of DNA, JVCI Syn3.0 can reproduce autonomously, but it certainly isn’t robust. Keeping it alive requires a coddling environment — essentially a life-support system. To arrive at a slightly more stable and robust organism that reproduced faster, the team later added back 19 genes to arrive at JVCI Syn3A.4 When combined, this work provides an approximate boundary for the simplest possible self-replicating life. We are clearly approaching the limit of viable cell simplicity. It seems safe to conclude that at least 400 genes (and approximately 500,000 base pairs of DNA) are the minimum requirements to produce a self-replicating cell. 

Exporting to the Environment

Second, we know that the process of simplifying an existing cell by removing some of its functionality doesn’t actually simplify the overall problem — it only exports the required complexity to the environment. A complex, robust cell can survive in changing conditions with varying food sources. A simplified cell becomes dependent on the environment to provide a constant, precise stream of the required nutrients. In other words, the simplified cell has reduced ability to maintain homeostasis, so the cell can only remain alive if the environment takes on the responsibility for homeostasis. Referring to JVCI Syn3A, Thornberg et al. conclude, “Unlike most organisms, which have synthesis pathways for most of [their] building blocks, Syn3A has been reduced to the point where it relies on having to transport them in.”This implies that the environment must provide a continuous supply of more specific and complex nutrients. The only energy source that JVCI Syn3A can process is glucose,4 so the environment must provide a continuous supply of its only tolerable food. Intelligent humans can provide such a coddling life-support environment, but a prebiotic Earth could not. Protocells would therefore place untenable requirements on their environment, and the requirements would have to be consistently met for millions of years.

Striving for Simplicity

Third, we know that existing microbes are constantly trying to simplify themselves, to the extent that their environment will allow. In Richard Lenski’s famous E. coli experiment, the bacteria simplified themselves by jettisoning their ribose operons after a few thousand generations, because they didn’t need to metabolize ribose and they could replicate 2 percent faster without it, providing a selective advantage.6 Furthermore, Kuo and Ochman studied the well-established preference of prokaryotes to minimize their own DNA, concluding: “deletions outweigh insertions by at least a factor of 10 in most prokaryotes.”7 This means that existing life has been trying from the very start to be as simple as possible. Therefore, it is likely that extant life has already reached something close to the simplest possible form, unless experimenters like Lenski provide a coddling environment for a long duration that allows further simplification. But such an environment requires the intervention of intelligent humans to provide just the right ingredients, at the right concentrations, and at the right time. No prebiotic environment could do this. Therefore, scientists need not try to simplify existing life — we already have good approximations of the simplest form. Indeed, Mycoplasma genitalium has a genome of 580,000 base pairs and 468 genes8 whereas Craig Venter’s minimal “synthetic cell” JVCI Syn3.0 has a comparable genome of 520,000 base pairs and 473 genes.3

The data provide a clear picture: the surprising complexity of even the simplest forms of existing life — 500,00 base pairs of DNA — cannot be avoided and cannot be reduced unless intelligent agents provide a complex life-support environment. Because protocells would have had to survive and reproduce on a harsh and otherwise lifeless planet, protocells are not a viable concept. Protocells place origin-of-life researchers in a rather awkward position: relying upon an imaginary entity to sustain their belief that only matter and energy exist.

Man to man is a wolf II


The ministry of truth is a thing?

Byzantium:A brief history.

Byzantium (/bɪˈzæntiəm, -ʃəm/) or Byzantion (Greek: Βυζάντιον) was an ancient Greek city in classical antiquity that became known as Constantinople in late antiquity and Istanbul today. The Greek name Byzantion and its Latinization Byzantium continued to be used as a name of Constantinople sporadically and to varying degrees during the thousand year existence of the Byzantine Empire.[1][2] Byzantium was colonized by Greeks from Megara in the 7th century BC and remained primarily Greek-speaking until its conquest by the Ottoman Empire in AD 1453.[3]

 

Etymology

The etymology of Byzantium is unknown. It has been suggested that the name is of Thracian origin.[4] It may be derived from the Thracian personal name Byzas which means "he-goat".[5][6] Ancient Greek legend refers to the Greek king Byzas, the leader of the Megarian colonists and founder of the city.[7] The name Lygos for the city, which likely corresponds to an earlier Thracian settlement,[4] is mentioned by Pliny the Elder in his Natural History.[8]

Byzántios, plural Byzántioi (Ancient Greek: Βυζάντιος, Βυζάντιοι, Latin: Byzantius; adjective the same) referred to Byzantion's inhabitants, also used as an ethnonym for the people of the city and as a family name.[5] In the Middle Ages, Byzántion was also a synecdoche for the eastern Roman Empire. (An ellipsis of Medieval Greek: Βυζάντιον κράτος, romanizedByzántion krátos).[5] Byzantinós (Medieval Greek: Βυζαντινός, Latin: Byzantinus) denoted an inhabitant of the empire.[5] The Anglicization of Latin Byzantinus yielded "Byzantine", with 15th and 16th century forms including Byzantin, Bizantin(e), Bezantin(e), and Bysantin as well as Byzantian and Bizantian.[9]

The name Byzantius and Byzantinus were applied from the 9th century to gold Byzantine coinage, reflected in the French besant (d'or), Italian bisante, and English besant, byzant, or bezant.[5] The English usage, derived from Old French besan (pl. besanz), and relating to the coin, dates from the 12th century.[10]

Later, the name Byzantium became common in the West to refer to the Eastern Roman Empire, whose capital was Constantinople. As a term for the east Roman state as a whole, Byzantium was introduced by the historian Hieronymus Wolf only in 1555, a century after the last remnants of the empire, whose inhabitants continued to refer to their polity as the Roman Empire (Medieval Greek: Βασιλεία τῶν Ῥωμαίων, romanizedBasileía tōn Rhōmaíōn, lit.'empire of the Romans'), had ceased to exist.[11]

Other places were historically known as Byzántion (Βυζάντιον) – a city in Libya mentioned by Stephanus of Byzantium and another on the western coast of India referred to by the Periplus of the Erythraean Sea; in both cases the names were probably adaptations of names in local languages.[5] Faustus of Byzantium was from a city of that name in Cilicia.[5]

  History

 

The origins of Byzantium are shrouded in legend. Tradition says that Byzas of Megara (a city-state near Athens) founded the city when he sailed northeast across the Aegean Sea. The date is usually given as 667 BC on the authority of Herodotus, who states the city was founded 17 years after Chalcedon. Eusebius, who wrote almost 800 years later, dates the founding of Chalcedon to 685/4 BC, but he also dates the founding of Byzantium to 656 BC (or a few years earlier depending on the edition). Herodotus' dating was later favored by Constantine the Great, who celebrated Byzantium's 1000th anniversary between the years 333 and 334.[12]

Byzanitium was mainly a trading city due to its location at the Black Sea's only entrance. Byzantium later conquered Chalcedon, across the Bosphorus on the Asiatic side.

The city was taken by the Persian Empire at the time of the Scythian campaign (513 BC) of King Darius I (r. 522–486 BC), and was added to the administrative province of Skudra.[13] Though Achaemenid control of the city was never as stable as compared to other cities in Thrace, it was considered, alongside Sestos, to be one of the foremost Achaemenid ports on the European coast of the Bosphorus and the Hellespont.[13]

Byzantium was besieged by Greek forces during the Peloponnesian War. As part of Sparta's strategy for cutting off grain supplies to Athens during their siege of Athens, Sparta took control of the city in 411 BC, to bring the Athenians into submission. The Athenian military later retook the city in 408 BC, when the Spartans had withdrawn following their settlement.[14]

After siding with Pescennius Niger against the victorious Septimius Severus, the city was besieged by Roman forces and suffered extensive damage in AD 196.[15] Byzantium was rebuilt by Septimius Severus, now emperor, and quickly regained its previous prosperity. It was bound to Perinthus during the period of Septimius Severus.[citation needed] The strategic and highly defensible (due to being surrounded by water on almost all sides) location of Byzantium attracted Roman Emperor Constantine I who, in AD 330, refounded it as an imperial residence inspired by Rome itself, known as Nova Roma. Later the city was called Constantinople (Greek Κωνσταντινούπολις, Konstantinoupolis, "city of Constantine").

This combination of imperialism and location would affect Constantinople's role as the nexus between the continents of Europe and Asia. It was a commercial, cultural, and diplomatic centre and for centuries formed the capital of the Byzantine Empire, which decorated the city with numerous monuments, some still standing today. With its strategic position, Constantinople controlled the major trade routes between Asia and Europe, as well as the passage from the Mediterranean Sea to the Black Sea. On May 29, 1453, the city fell to the Ottoman Turks, and again became the capital of a powerful state, the Ottoman Empire. The Turks called the city "Istanbul" (although it was not officially renamed until 1930); the name derives from "eis-ten-polin" (Greek: "to-the-city"). To this day it remains the largest and most populous city in Turkey, although Ankara is now the national capital.

Emblem

 

By the late Hellenistic or early Roman period (1st century BC), the star and crescent motif was associated to some degree with Byzantium; even though it became more widely used as the royal emblem of Mithradates VI Eupator (who for a time incorporated the city into his empire).[16]

Some Byzantine coins of the 1st century BC and later show the head of Artemis with bow and quiver, and feature a crescent with what appears to be an eight-rayed star on the reverse. According to accounts which vary in some of the details, in 340 BC the Byzantines and their allies the Athenians were under siege by the troops of Philip of Macedon. On a particularly dark and wet night Philip attempted a surprise attack but was thwarted by the appearance of a bright light in the sky. This light is occasionally described by subsequent interpreters as a meteor, sometimes as the moon, and some accounts also mention the barking of dogs. However, the original accounts mention only a bright light in the sky, without specifying the moon.[a][b] To commemorate the event the Byzantines erected a statue of Hecate lampadephoros (light-bearer or bringer). This story survived in the works of Hesychius of Miletus, who in all probability lived in the time of Justinian I. His works survive only in fragments preserved in Photius and the tenth century lexicographer Suidas. The tale is also related by Stephanus of Byzantium, and Eustathius.

Devotion to Hecate was especially favored by the Byzantines for her aid in having protected them from the incursions of Philip of Macedon. Her symbols were the crescent and star, and the walls of her city were her provenance.[19]

It is unclear precisely how the symbol Hecate/Artemis, one of many goddesses[c] would have been transferred to the city itself, but it seems likely to have been an effect of being credited with the intervention against Philip and the subsequent honors. This was a common process in ancient Greece, as in Athens where the city was named after Athena in honor of such an intervention in time of war.

Cities in the Roman Empire often continued to issue their own coinage. "Of the many themes that were used on local coinage, celestial and astral symbols often appeared, mostly stars or crescent moons."[21] The wide variety of these issues, and the varying explanations for the significance of the star and crescent on Roman coinage precludes their discussion here. It is, however, apparent that by the time of the Romans, coins featuring a star or crescent in some combination were not at all rare.

Notes


  1. "In 324 Byzantium had a number of operative cults to traditional gods and goddesses tied to its very foundation eight hundred years before. Rhea, called "the mother of the gods" by Zosimus, had a well-ensconced cult in Byzantium from its very foundation. [...] Devotion to Hecate was especially favored by the Byzantines [...] Constantine would also have found Artemis-Selene and Aphrodite along with the banished Apollo Zeuxippus on the Acropolis in the old Greek section of the city. Other gods mentioned in the sources are Athena, Hera, Zeus, Hermes, and Demeter and Kore. Even evidence of Isis and Serapis appears from the Roman era on coins during the reign of Caracalla and from inscriptions." [20]

In the course of this beleaguerment, it is related, on a certain wet and moonless night the enemy attempted a surprise, but were foiled by reason of a bright light which, appearing suddenly in the heavens, startled all the dogs in the town and thus roused the garrison to a sense of their danger. To commemorate this timely phenomenon, which was attributed to Hecate, they erected a public statue to that goddess [...]"[17]

  • "If any goddess had a connection with the walls in Constantinople, it was Hecate. Hecate had a cult in Byzantium from the time of its founding. Like Byzas in one legend, she had her origins in Thrace. Since Hecate was the guardian of "liminal places," in Byzantium small temples in her honor were placed close to the gates of the city. Hecate's importance to Byzantium was above all as deity of protection. When Philip of Macedon was about to attack the city, according to the legend she alerted the townspeople with her ever-present torches, and with her pack of dogs, which served as her constant companions. Her mythic qualities thenceforth forever entered the fabric of Byzantine history. A statue known as the 'Lampadephoros' was erected on the hill above the Bosphorous to commemorate Hecate's defensive aid."[18]

    Unexplained — Maybe Unexplainable — Numbers Control the Universe

    Evolution News
     

    In Carl Sagan’s Contact, the extraterrestrials embedded a message in the irrational number pi (the circumference of a circle divided by its radius). But some other numbers are critical to the structure of our universe too — and why they are critical does not make obvious sense.

    • Perhaps the most fundamental and mysterious one is the fine structure constant of the universe:

    A seemingly harmless, random number with no units or dimensions has cropped up in so many places in physics and seems to control one of the most fundamental interactions in the universe.

    Its name is the fine-structure constant, and it’s a measure of the strength of the interaction between charged particles and the electromagnetic force. The current estimate of the fine-structure constant is 0.007 297 352 5693, with an uncertainty of 11 on the last two digits. The number is easier to remember by its inverse, approximately 1/137.

    If it had any other value, life as we know it would be impossible. And yet we have no idea where it comes from. 

    PAUL SUTTER, “LIFE AS WE KNOW IT WOULD NOT EXIST WITHOUT THIS HIGHLY UNUSUAL NUMBER” AT SPACE.COM (MARCH 24, 2022)

    Many famous scientists have reflected on 1/137:

    The brilliant physicist Richard Feynman (1918-1988) famously thought so, saying there is a number that all theoretical physicists of worth should “worry about”. He called it “one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man”…

    What’s special about alpha is that it’s regarded as the best example of a pure number, one that doesn’t need units. It actually combines three of nature’s fundamental constants – the speed of light, the electric charge carried by one electron, and the Planck’s constant, as explains physicist and astrobiologist Paul Davies to Cosmos magazine. Appearing at the intersection of such key areas of physics as relativity, electromagnetism and quantum mechanics is what gives 1/137 its allure. 

    PAUL RATNER, “WHY THE NUMBER 137 IS ONE OF THE GREATEST MYSTERIES IN PHYSICS” AT BIG THINK (OCTOBER 31, 2018)

    First Question to the Devil

    Nobelist Wolfgang Pauli (1945) is said to have remarked, “When I die, my first question to the devil will be: What is the meaning of the fine structure constant?” At any rate, he thought about it a great deal during his life.

    University of Nottingham physics professor Laurence Eaves thinks the number 1/137 would be good for starting communication with intelligent aliens as they would be likely to know about it and to realize they were dealing with other intelligent entities.

    • Here’s another thought-provoking number. Consider the irrational number known as phi (ϕ) or the Golden Ratio. Jordan Ellenberg author of Shape: The Hidden Geometry of Information, Biology, Strategy, Democracy, and Everything Else (2021):

    Among the mysteries of the irrationals, one number holds a special place: the so-called golden ratio. The golden ratio’s value is about 1.618 (but not exactly 1.618, since then it would be the ratio 1,618/1,000, and therefore not irrational) and it’s also referred to by the Greek letter φ, which is pronounced “fee” if you’re a mathematician and “fie” if you are in a fraternity. If you want an exact description, the golden ratio can be expressed as (1/2)(1+√5.)

    JORDAN ELLENBERG, “THE MOST IRRATIONAL NUMBER” AT SLATE (JUNE 8, 2021)

    The “Divine Proportion”

    We find this number everywhere too:

    The golden ratio is sometimes called the “divine proportion,” because of its frequency in the natural world. The number of petals on a flower, for instance, will often be a Fibonacci number. The seeds of sunflowers and pine cones twist in opposing spirals of Fibonacci numbers. Even the sides of an unpeeled banana will usually be a Fibonacci number — and the number of ridges on a peeled banana will usually be a larger Fibonacci number.

    • Then there is pi (π), which (outside of Carl Sagan’s novel and film) burbles on forever without forming a pattern, yet it is fundamental in nature too.

    How Does the Intelligibility of Nature Point to Design?

    Bruce Gordon
     

    Editor’s note: This article is an excerpt from the newly released book The Comprehensive Guide to Science and Faith: Exploring the Ultimate Questions About Life and the Cosmos

    Albert Einstein (1879–1955) famously remarked that “the eternal mystery of the world is its comprehensibility…[t]he fact that it is comprehensible is a miracle.” Similarly, the mathematical physicist Eugene Wigner (1902–1995) opined that “[t]he miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve.” 

    As these remarks highlight, the intelligibility of the universe to the human mind requires explanation in two respects. The first is ontological: Why is nature ordered in such a way that it can be understood? The second is epistemological: Why is the human mind able to gain understanding of the natural order? In the past, these questions did not provoke the puzzlement they do today. Let’s get some historical perspective on the rise of modern science and the current milieu before we examine why a metaphysically naturalistic worldview provides no good answers to these questions, and why theism, which understands the universe as the product of intelligent design, is the only metaphysical context in which the existence and intelligibility of nature has an explanation.

    Historical Perspective

    For science to be possible, there must be order present in nature, and it has to be discoverable by the human mind. But why should either of these conditions be met? Historically, while there were temporary manifestations of systematic research into nature in ancient Greece and early Islam, and isolated discoveries elsewhere, the seeds of modern science first came to concentrated and sustained fruition in Western culture before its methodologies and achievements were disseminated throughout the world. 

    This lasting and world-changing development emerged in the context of the Judeo-Christian worldview that permeated medieval Europe. What drove it was a deeply entrenched society-wide conception of the universe as the free and rational creation of God’s mind so that human beings, as rational creatures made in God’s image, were capable of searching out and understanding a divinely ordered reality. The freedom of God’s creative will meant that this order could not be abstractly deduced ― it had to be discovered through observation and experiment ― but God’s stable and faithful character guaranteed it had a rational structure that diligent study could reveal. This theological foundation gave solid answers to ontological and epistemological questions concerning the intelligibility of the universe, but as the quotes from Einstein and Wigner make clear, this foundation had been lost by the middle of the 20th century. Why?

    Efficient and Material Causes

    Some see it as the outworking of the 17th-century mechanical philosophy that sought to explain all natural phenomena in terms of material contact mechanisms. On this view, mechanical philosophy conceptually reduced scientific causality to efficient and material causes, purging Aristotelian notions of formal and final causality from science. This is perhaps plausible methodologically, but not metaphysically. The conception of mechanism in the mechanical philosophy retained formal causes in their design and final causes in the purpose they were created to serve. The break with Aristotle arose from the fact that, in the conception of the theistic and deistic mechanical philosophers, design and purpose were transcendently imposed rather than immanently active, so the search for scientific explanations turned to the intelligent implementation of efficient material mechanisms. The purge of any sense of design and purpose from the “scientific” conception of nature is due to the late-19th-century rise of Darwinian philosophy, which sees the mechanisms of nature as brute facts and the course of their development as completely blind and purposeless.

    Under the Aegis of Naturalism

    It is Darwinism, so conceived, that renders the existence of mathematically describable regularities in nature and their intelligibility to the human mind (itself conceived as the accidental result of blind processes) as such a surprise, for it assumes naturalism ― the self-contained character of nature and the denial of supernaturalism ― as the context for science. Under the aegis of naturalism, there can be no expectation that nature is regular in a way that allows presently operative causes to be projected into the past to explain the current state of the universe or into the future to predict its development. The absence of any sufficient cause to explain why nature exists leaves the philosophical naturalist with no reason to think that what does exist should be ordered, or that any order he finds should be projectable into the past or the future. 

    By denying transcendence and defaulting to a conception of the universe as a closed and ultimately arbitrary system of causes and effects, naturalism makes science the uncanny enterprise on which Einstein and Wigner remarked. On the other hand, the Judeo-Christian worldview recognizes that nature exists and is regular not because it is closed to divine activity, but because (and only because) divine causality is operative. It is only because nature is a creation and thus not a closed system of causes and effects that it exists in the first place and exhibits the regular order that makes science possible. God’s existence and action is not an obstacle to science; it’s what makes it possible.

    We don’t know who made them. We don’t know how they were made. We don’t know what purpose they served. But we know they were intentionally made by mindful individuals. At least, Live Science never questions the design inference about strange stone structures in Middle Eastern deserts that are shaped like wheels, triangles, and long lines (see the photo gallery).

    Why Is Design the Obvious Inference?

    There are hundreds of these structures. They extend over much of the Middle East: Syria, Jordan, Saudi Arabia, and Yemen. 

    The “works of the old men” include wheels, which often have spokes radiating out from the center, kites (stone structures used for funnelling and killing animals), pendants (lines of stone cairns) and meandering walls, which are mysterious structures that meander across the landscape for up to several hundred feet.

    The works “demonstrate specific geometric patterns and extend from a few tens of meters up to several kilometers, evoking parallels to the well-known system of geometric lines of Nazca, Peru,” wrote an archaeological team in a paper published recently in the Journal of Archaeological Science. (Peru’s Nazca Lines date to between 200 B.C. and A.D. 500.). [Emphasis added.]

    World War I pilots readily inferred they were man-made. Bedouins call them the “works of the old men,” but apparently do not know who the “old men” were. It’s not clear what they were used for. The wheels might have been for forecasting seasons, since they tend to be aligned northwest to southeast to match sunrise at the winter solstice. But why the triangles? And the hundreds of “gates” with their long parallel lines? Who would make large structures that can’t be seen readily from ground level?

    Why people in prehistoric times would build wheel-shaped structures that can’t be seen well from the ground remains a mystery. No balloon or glider technologies existed at that time. Additionally, researchers say that climbing to a higher elevation to view them was probably not possible, at least not in most cases. 

    Older than the Nazca Lines

    New research using optically stimulated luminescence on the stones has produced dates of about 8,500 years for a couple of the structures. That makes them older than the Nazca lines. Were they burial structures? Signals to their gods? Animal traps?

    Other points of interest aside, the mystery serves to illustrate the logic of the design inference. These structures demonstrate that it’s not necessary to know (1) the identity of the designer, (2) the motivation or purpose of the designer, or (3) the function of the design. It’s also not necessary to know when they were made, or how. 

    To make the design inference robust, however, it’s important not to jump to conclusions. There are similar shapes in nature that are not considered designed. In fact, there are vast areas of circular shapes in the Namibian desert that have defied explanation for years (see Science Daily). 

    Desert fairy circles are considered one of nature’s greatest mysteries because no one knows how they form. Different from mushroom rings, these fairy circles are large barren patches of earth ringed by short grass dotting the desert like craters on the moon or big freckles. Several groups are racing to figure out this bizarre phenomenon.

    Geometric structures made by animals — like circular shells of diatoms, bird nests, or honeycombs — we do not attribute to the work of sentient beings. These are built instinctively for reproduction, feeding, or other life necessities. Intelligent agents like humans can organize natural materials for necessities, too, but have the free will to make things for other purposes — “gratuitous” purposes like art, conceptual communication, or ritual. Crows and chimps can make crude tools, but humans can make tools to make other tools. Animals make tools to eat. Humans make tools to explore outer space and email currency across the globe.

    The Line Gets Fuzzy

    Admittedly those are extreme examples. The line can get fuzzy in the middle. So how do we infer design for the geoglyphs in Jordan, but not the fairy circles in Namibia or the intricate circles in diatom shells? Here is where the Design Filter comes in:

    1. Can the geoglyphs be explained by chance? No; stones do not randomly collect into triangles, wheels with spokes, and parallel lines due to unguided causes like storms or earthquakes. Circular craters can emerge by chance, due to meteor impacts or volcanic eruptions, but they do not look like these, and there is no evidence of shocked minerals or lava present.
    2. Can they be explained by natural law? Natural forces can produce spirals like galaxies and hurricanes. They do not typically produce spoked wheels or triangles (see this earlier article at Evolution News). A bent-over blade of grass could trace out a circle as the wind shifts direction, like a compass. Snowflakes can produce a semblance of spoked wheels, but we know about the atomic forces that cause water to crystallize in hexagonal shapes. Nothing like that works on the scale of kilometers to arrange stones that way, especially aligning them with sunrise at winter solstice.
    3. Is there a specification? Yes; we see an independent specification of the solstice that could guide a sentient being to choose to arrange stones with that preferred orientation. We also understand the human mind’s attraction for geometry and mathematics. 

    More Intuitive than Robust

    To be sure, the design inference for these structures is more intuitive than robust. It’s conceivable that scientists may find a combination of natural laws and chance that generates these structures in that part of the world; unlikely, but possible. And since we don’t know of any clear purpose for the structures, our third test (specification) is weaker than one might like. Despite these caveats, the design inference is pretty sound. Nobody from the Bedouins to the pilots is questioning it. Compare this case to earlier archaeological mysteries that are more dubious.

    Evolutionists try to explain the human mind as the product of chance and natural law, claiming it is the product of natural selection. The human mind is like animal design, they will say, simply more of the same. What’s the answer to that? Just turn it around. Such a position implies that the scientist’s propensity to speculate about evolution is also a product of natural selection. So if the evolutionists’ position is the result of blind, unguided processes, and if mental activity is an illusion, then reason evaporates; they have no way of knowing anything is true. John West’s book The Magician’s Twin sheds further light on this “argument from reason.”

    Meanwhile, design advocates think that animals and their designs pass the design filter, too. Their bodies, behaviors, and instincts are the products of genetic instructions, making them act in a programmed way. We reasonably infer that their origins are the result of an intelligent cause.

    Lukas Ruegger: Homology and Phylogenetics Topple Darwin’s Tree

    David Klinghoffer
     
     

    I like that the new video series from ID explainer Lukas Ruegger, Basics of Intelligent Design Biology, is being released week by week rather than, as could have been the case, as one longer video. This way, the “drip, drip, drip” effect comes into play: Episodes 1 through 3 successively narrowed some available escape routes for Darwin’s troubled theory. In a brief manner that’s like an alternative and much more accurate version of Khan Academy’s science-challenged treatment of the subject, Ruegger showed why the fossil record offers poor evidence for evolution. (See herehere, and here.)

    Perhaps with that distressing reality in mind, Richard Dawkins and others have said that the case for Darwinian evolution is perfectly sound even without fossils. Evolutionists, instead, have all the evidence they need in genes and morphology to draw the one true tree of life. In Episode 4, which is out today, Lukas asks, “Do Homology and Phylogenetics REALLY Support Darwin’s Tree of Life?” The problem is that the “trees” thus sketched are full of fundamental, mutual contradictions. Even if universal common ancestry is true, there seemingly is no drawable “true tree.” As Lukas says, “Those who study homology simply assume evolution to be true, but they’ve never actually demonstrated that the ancestral evolutionary relationships between different organisms are real.”

     And, “If the hard facts of paleontology oppose the notion of there being a tree of life, and if that supposed tree of life cannot be independently established by genetic homologies, well, what evidence for Darwin’s tree of life are we left with?” The answer that Khan Academy doesn’t want you to hear is: Not much.

    Researchers Ask — Serious Question — Do Crabs Have Emotions?

    At one time, the question of whether crabs or squid had emotions would seem ridiculous. Dogs and cats have emotions but squid and crabs don’t. Right? But in recent decades, it has become evident that there is no straightforward evolutionary path to “smartness.” What about the ability to experience pain or emotion as a dog or cat would?

    “A London School of Economics (LSE) report commissioned by the U.K. government found there is strong enough evidence to conclude that decapod crustaceans and cephalopod molluscs are sentient,” says York University Professor and philosopher Kristin Andrews, the York Research Chair in Animal Minds, who is working with the LSE team.

    Andrews co-wrote an article published today in the journal Science, “The question of animal emotions,” with Professor Frans de Waal, director of the Living Links Center at Emory University, which discusses the ethical and policy issues around animals being considered sentient.

    Unexpected Ethical Issues

    The view that exothermic (coldblooded) and invertebrate animals might have feelings raises ethical issues, says Kristin Andrews, author of How to Study Animal Minds (Cambridge, 2020):

    “If they can no longer be considered immune to felt pain, invertebrate experiences will need to become part of our species’ moral landscape,” she says. “But pain is just one morally relevant emotion. Invertebrates such as octopuses may experience other emotions such as curiosity in exploration, affection for individuals, or excitement in anticipation of a future reward.”

    But It Gets Complex

    Researchers have been working on this question and the results are mixed. Some invertebrates, like octopuses show evidence of emotion and intelligence, roughly the same as lab rats. Others, like the octopus’s shelly distant cousin, the nautilus, just don’t check out that way.

    Some researchers think that a shell reduces the need for intelligence so the octopus became more intelligent, relative to the nautilus, as a result of losing its shell. Others disagree. The problem is, they say, the octopus would need to increase in intelligence 275 million years ago, before losing its shell. Otherwise, it would simply have been eaten to extinction. But in that case, what was the driver for intelligence? In any event, shelly crabs and lobsters also show unexpected intelligence.

    The practical question is, can the seafood industry continue to ignore the possibility that their catches feel pain?
