Psalm36-42NASB

36)For the choir director. A Psalm of David the servant of the LORD.

1Transgression speaks to the ungodly within his heart;
            There is no fear of God before his eyes.
      2For it flatters him in his own eyes
            Concerning the discovery of his iniquity and the hatred of it.

      3The words of his mouth are wickedness and deceit;
            He has ceased to be wise and to do good.

      4He plans wickedness upon his bed;
            He sets himself on a path that is not good;
            He does not despise evil.

      5Your lovingkindness, O LORD, extends to the heavens,
            Your faithfulness reaches to the skies.

      6Your righteousness is like the mountains of God;
            Your judgments are like a great deep.
            O LORD, You preserve man and beast.

      7How precious is Your lovingkindness, O God!
            And the children of men take refuge in the shadow of Your wings.

      8They drink their fill of the abundance of Your house;
            And You give them to drink of the river of Your delights.

      9For with You is the fountain of life;
            In Your light we see light.

      10O continue Your lovingkindness to those who know You,
            And Your righteousness to the upright in heart.

      11Let not the foot of pride come upon me,
            And let not the hand of the wicked drive me away.

      12There the doers of iniquity have fallen;
            They have been thrust down and cannot rise.

37)A Psalm of David.

1Do not fret because of evildoers,
            Be not envious toward wrongdoers.
      2For they will wither quickly like the grass
            And fade like the green herb.

      3Trust in the LORD and do good;
            Dwell in the land and cultivate faithfulness.

      4Delight yourself in the LORD;
            And He will give you the desires of your heart.

      5Commit your way to the LORD,
            Trust also in Him, and He will do it.

      6He will bring forth your righteousness as the light
            And your judgment as the noonday.

      7Rest in the LORD and wait patiently for Him;
            Do not fret because of him who prospers in his way,
            Because of the man who carries out wicked schemes.

      8Cease from anger and forsake wrath;
            Do not fret; it leads only to evildoing.

      9For evildoers will be cut off,
            But those who wait for the LORD, they will inherit the land.

      10Yet a little while and the wicked man will be no more;
            And you will look carefully for his place and he will not be there.

      11But the humble will inherit the land
            And will delight themselves in abundant prosperity.

      12The wicked plots against the righteous
            And gnashes at him with his teeth.

      13The Lord laughs at him,
            For He sees his day is coming.

      14The wicked have drawn the sword and bent their bow
            To cast down the afflicted and the needy,
            To slay those who are upright in conduct.

      15Their sword will enter their own heart,
            And their bows will be broken.

      16Better is the little of the righteous
            Than the abundance of many wicked.

      17For the arms of the wicked will be broken,
            But the LORD sustains the righteous.

      18The LORD knows the days of the blameless,
            And their inheritance will be forever.

      19They will not be ashamed in the time of evil,
            And in the days of famine they will have abundance.

      20But the wicked will perish;
            And the enemies of the LORD will be like the glory of the pastures,
            They vanish—like smoke they vanish away.

      21The wicked borrows and does not pay back,
            But the righteous is gracious and gives.

      22For those blessed by Him will inherit the land,
            But those cursed by Him will be cut off.

      23The steps of a man are established by the LORD,
            And He delights in his way.

      24When he falls, he will not be hurled headlong,
            Because the LORD is the One who holds his hand.

      25I have been young and now I am old,
            Yet I have not seen the righteous forsaken
            Or his descendants begging bread.

      26All day long he is gracious and lends,
            And his descendants are a blessing.

      27Depart from evil and do good,
            So you will abide forever.

      28For the LORD loves justice
            And does not forsake His godly ones;
            They are preserved forever,
            But the descendants of the wicked will be cut off.

      29The righteous will inherit the land
            And dwell in it forever.

      30The mouth of the righteous utters wisdom,
            And his tongue speaks justice.

      31The law of his God is in his heart;
            His steps do not slip.

      32The wicked spies upon the righteous
            And seeks to kill him.

      33The LORD will not leave him in his hand
            Or let him be condemned when he is judged.

      34Wait for the LORD and keep His way,
            And He will exalt you to inherit the land;
            When the wicked are cut off, you will see it.

      35I have seen a wicked, violent man
            Spreading himself like a luxuriant tree in its native soil.

      36Then he passed away, and lo, he was no more;
            I sought for him, but he could not be found.

      37Mark the blameless man, and behold the upright;
            For the man of peace will have a posterity.

      38But transgressors will be altogether destroyed;
            The posterity of the wicked will be cut off.

      39But the salvation of the righteous is from the LORD;
            He is their strength in time of trouble.

      40The LORD helps them and delivers them;
            He delivers them from the wicked and saves them,
            Because they take refuge in Him.

38)A Psalm of David, for a memorial.

1O LORD, rebuke me not in Your wrath,
            And chasten me not in Your burning anger.
      2For Your arrows have sunk deep into me,
            And Your hand has pressed down on me.

      3There is no soundness in my flesh because of Your indignation;
            There is no health in my bones because of my sin.

      4For my iniquities are gone over my head;
            As a heavy burden they weigh too much for me.

      5My wounds grow foul and fester
            Because of my folly.

      6I am bent over and greatly bowed down;
            I go mourning all day long.

      7For my loins are filled with burning,
            And there is no soundness in my flesh.

      8I am benumbed and badly crushed;
            I groan because of the agitation of my heart.

      9Lord, all my desire is before You;
            And my sighing is not hidden from You.

      10My heart throbs, my strength fails me;
            And the light of my eyes, even that has gone from me.

      11My loved ones and my friends stand aloof from my plague;
            And my kinsmen stand afar off.

      12Those who seek my life lay snares for me;
            And those who seek to injure me have threatened destruction,
            And they devise treachery all day long.

      13But I, like a deaf man, do not hear;
            And I am like a mute man who does not open his mouth.

      14Yes, I am like a man who does not hear,
            And in whose mouth are no arguments.

      15For I hope in You, O LORD;
            You will answer, O Lord my God.

      16For I said, “May they not rejoice over me,
            Who, when my foot slips, would magnify themselves against me.”

      17For I am ready to fall,
            And my sorrow is continually before me.

      18For I confess my iniquity;
            I am full of anxiety because of my sin.

      19But my enemies are vigorous and strong,
            And many are those who hate me wrongfully.

      20And those who repay evil for good,
            They oppose me, because I follow what is good.

      21Do not forsake me, O LORD;
            O my God, do not be far from me!

      22Make haste to help me,
            O Lord, my salvation!

39)For the choir director, for Jeduthun. A Psalm of David.

1I said, “I will guard my ways
            That I may not sin with my tongue;
            I will guard my mouth as with a muzzle
            While the wicked are in my presence.”
      2I was mute and silent,
            I refrained even from good,
            And my sorrow grew worse.

      3My heart was hot within me,
            While I was musing the fire burned;
            Then I spoke with my tongue:

      4“LORD, make me to know my end
            And what is the extent of my days;
            Let me know how transient I am.

      5“Behold, You have made my days as handbreadths,
            And my lifetime as nothing in Your sight;
            Surely every man at his best is a mere breath. 

Selah.
      6“Surely every man walks about as a phantom;
            Surely they make an uproar for nothing;
            He amasses riches and does not know who will gather them.

      7“And now, Lord, for what do I wait?
            My hope is in You.

      8“Deliver me from all my transgressions;
            Make me not the reproach of the foolish.

      9“I have become mute, I do not open my mouth,
            Because it is You who have done it.

      10“Remove Your plague from me;
            Because of the opposition of Your hand I am perishing.

      11“With reproofs You chasten a man for iniquity;
            You consume as a moth what is precious to him;
            Surely every man is a mere breath. 

Selah.
      12“Hear my prayer, O LORD, and give ear to my cry;
            Do not be silent at my tears;
            For I am a stranger with You,
            A sojourner like all my fathers.

      13“Turn Your gaze away from me, that I may smile again
            Before I depart and am no more.”

40)For the choir director. A Psalm of David.

1I waited patiently for the LORD;
            And He inclined to me and heard my cry.
      2He brought me up out of the pit of destruction, out of the miry clay,
            And He set my feet upon a rock making my footsteps firm.

      3He put a new song in my mouth, a song of praise to our God;
            Many will see and fear
            And will trust in the LORD.

      4How blessed is the man who has made the LORD his trust,
            And has not turned to the proud, nor to those who lapse into falsehood.

      5Many, O LORD my God, are the wonders which You have done,
            And Your thoughts toward us;
            There is none to compare with You.
            If I would declare and speak of them,
            They would be too numerous to count.

      6Sacrifice and meal offering You have not desired;
            My ears You have opened;
            Burnt offering and sin offering You have not required.

      7Then I said, “Behold, I come;
            In the scroll of the book it is written of me.

      8I delight to do Your will, O my God;
            Your Law is within my heart.”

      9I have proclaimed glad tidings of righteousness in the great congregation;
            Behold, I will not restrain my lips,
            O LORD, You know.

      10I have not hidden Your righteousness within my heart;
            I have spoken of Your faithfulness and Your salvation;
            I have not concealed Your lovingkindness and Your truth from the great congregation.

      11You, O LORD, will not withhold Your compassion from me;
            Your lovingkindness and Your truth will continually preserve me.

      12For evils beyond number have surrounded me;
            My iniquities have overtaken me, so that I am not able to see;
            They are more numerous than the hairs of my head,
            And my heart has failed me.

      13Be pleased, O LORD, to deliver me;
            Make haste, O LORD, to help me.

      14Let those be ashamed and humiliated together
            Who seek my life to destroy it;
            Let those be turned back and dishonored
            Who delight in my hurt.

      15Let those be appalled because of their shame
            Who say to me, “Aha, aha!”

      16Let all who seek You rejoice and be glad in You;
            Let those who love Your salvation say continually,
            “The LORD be magnified!”

      17Since I am afflicted and needy,
            Let the Lord be mindful of me.
            You are my help and my deliverer;
            Do not delay, O my God.

41)For the choir director. A Psalm of David.

1How blessed is he who considers the helpless;
            The LORD will deliver him in a day of trouble.
      2The LORD will protect him and keep him alive,
            And he shall be called blessed upon the earth;
            And do not give him over to the desire of his enemies.

      3The LORD will sustain him upon his sickbed;
            In his illness, You restore him to health.

      4As for me, I said, “O LORD, be gracious to me;
            Heal my soul, for I have sinned against You.”

      5My enemies speak evil against me,
            “When will he die, and his name perish?”

      6And when he comes to see me, he speaks falsehood;
            His heart gathers wickedness to itself;
            When he goes outside, he tells it.

      7All who hate me whisper together against me;
            Against me they devise my hurt, saying,

      8“A wicked thing is poured out upon him,
            That when he lies down, he will not rise up again.”

      9Even my close friend in whom I trusted,
            Who ate my bread,
            Has lifted up his heel against me.

      10But You, O LORD, be gracious to me and raise me up,
            That I may repay them.

      11By this I know that You are pleased with me,
            Because my enemy does not shout in triumph over me.

      12As for me, You uphold me in my integrity,
            And You set me in Your presence forever.

      13Blessed be the LORD, the God of Israel,
            From everlasting to everlasting.
            Amen and Amen.

42)For the choir director. A Maskil of the sons of Korah.

1As the deer pants for the water brooks,
            So my soul pants for You, O God.
      2My soul thirsts for God, for the living God;
            When shall I come and appear before God?

      3My tears have been my food day and night,
            While they say to me all day long, “Where is your God?”

      4These things I remember and I pour out my soul within me.
            For I used to go along with the throng and lead them in procession to the house of God,
            With the voice of joy and thanksgiving, a multitude keeping festival.

      5Why are you in despair, O my soul?
            And why have you become disturbed within me?
            Hope in God, for I shall again praise Him
            For the help of His presence.

      6O my God, my soul is in despair within me;
            Therefore I remember You from the land of the Jordan
            And the peaks of Hermon, from Mount Mizar.

      7Deep calls to deep at the sound of Your waterfalls;
            All Your breakers and Your waves have rolled over me.

      8The LORD will command His lovingkindness in the daytime;
            And His song will be with me in the night,
            A prayer to the God of my life.

      9I will say to God my rock, “Why have You forgotten me?
            Why do I go mourning because of the oppression of the enemy?”

      10As a shattering of my bones, my adversaries revile me,
            While they say to me all day long, “Where is your God?”

      11Why are you in despair, O my soul?
            And why have you become disturbed within me?
            Hope in God, for I shall yet praise Him,
            The help of my countenance and my God.

File under 'well said' XIII

The spectacle of what is called religion, or at any rate organised religion, in India and elsewhere has filled me with horror, and I have frequently condemned it and wished to make a clean sweep of it. Almost always it seems to stand for blind belief and reaction, dogma and bigotry, superstition and exploitation, and the preservation of vested interests.

More aspirational hoodoo re:the Darwinian narrative on the origin of sight.

Optimistic Optics: Scientific American Makes Bold Claims About the Origin of the Eye
Jonathan M. June 23, 2011 6:00 AM 

A couple of weeks ago, an interesting article appeared in Scientific American, titled "Evolution Of The Eye." The subheading of the article makes the bold claim, "Scientists now have a clear vision of how our notoriously complex eye came to be." When I saw that this article had been published, I was immediately filled with a sense of intrigue. I looked forward to reading a proposed solution to a fiendishly vexing problem. What the article actually provided, however, was largely disappointing. There was nothing particularly new or original, and (though coated with our modern scientific understanding) the argument took, more or less, the same basic form that has been rehashed for the last century and a half since the publication of Darwin's On the Origin of Species.

The article actually makes explicit mention of intelligent design (ID) and offers the pertinent argument as a rebuttal to the concept of irreducible complexity. The author of the article, Trevor D. Lamb, claims that

... [B]iologists have recently made significant advances in tracing the origin of the eye--by studying how it forms in developing embryos and by comparing eye structure and genes across species to reconstruct when key traits arose. The results indicate that our kind of eye--the type common across vertebrates--took shape in less than 100 million years, evolving from a simple light sensor for circadian (daily) and seasonal rhythms around 600 million years ago to an optically and neurologically sophisticated organ by 500 million years ago. More than 150 years after Darwin published his groundbreaking theory, these findings put the nail in the coffin of irreducible complexity and beautifully support Darwin's idea. They also explain why the eye, far from being a perfectly engineered piece of machinery, exhibits a number of major flaws--these flaws are the scars of evolution. Natural selection does not, as some might think, result in perfection. It tinkers with the material available to it, sometimes to odd effect.
In a nutshell, the claims made by Lamb are as follows:

1. By comparing eye structures and embryological development of the eye in vertebrate species, one can infer that our camera eye has very ancient evolutionary roots.
2. Prior to acquiring the elements required for its operation as a visual organ, its function was simply the detection of light for modulating the circadian rhythms of our distant ancestors.

3. The eye has various design flaws and this is evidence for its evolutionary / dysteleological origin.

4. There are clues in developing embryos which indicate how the eye formed from a light-sensing but nonvisual organ into an image-forming one by around 500 million years ago.

Lamb's article is chiefly concerned with rebuffing intelligent design (and not merely demonstrating common ancestry). In this critique of the article, therefore, I want to focus primarily on the fourth of those points (which I deem to be the crux of the matter), and will also weigh in briefly on the apparent suboptimality of the eye's design.

Folding A Patch Of Photoreceptors
Lamb tells us,
Early in development, the neural structure that gives rise to the eye bulges out on either side to form two sacs, or vesicles. Each of these vesicles then folds in on itself to form a C-shaped retina that lines the interior of the eye. Evolution probably proceeded in much the same way. We postulate that a proto-eye of this kind--with a C-shaped, two-layered retina composed of ciliary photoreceptors on the exterior and output neurons derived from rhabdomeric photoreceptors on the interior--had evolved in an ancestor of vertebrates between 550 million and 500 million years ago, serving to drive its internal clock and perhaps help it to detect shadows and orient its body properly.
This insight is hardly novel. The idea has been espoused by many of the great evolutionary biologists of the 20th century (e.g. Richard Dawkins). Nilsson and Pelger (1994) also articulated a very similar argument (see David Berlinski's critique here).

In such models, it is thought that visual acuity might be improved first by the initially flat patch of photoreceptors becoming concave, and subsequently by increasing the level of indentation. The argument is, of course, predicated on the critical assumption that the change is both hereditable and able to be continued indefinitely (no matter how much indentation and selection has occurred previously).

Moreover, once the indented patch of photoreceptors is equally as deep as it is wide, visual acuity is most effectively enhanced, not by becoming deeper, but by constricting the orifice of the depression until an optimum is achieved with respect to the trade off between visual acuity (as a result of the narrowing of the angle of incident light to each respective photocell) and the reduction in light admitted to the photocells.

The Development And Evolution Of The Lens
Lamb continues,
In the next stage of embryological development, as the retina is folding inward against itself, the lens forms, originating as a thickening of the embryo's outer surface, or ectoderm, that bulges into the curved empty space formed by the C-shaped retina. This protrusion eventually separates from the rest of the ectoderm to become a free-floating element. It seems likely that a broadly similar sequence of changes occurred during evolution. We do not know exactly when this modification happened, but in 1994 researchers at Lund University in Sweden showed that the optical components of the eye could have easily evolved within a million years. If so, the image-forming eye may have arisen from the nonvisual proto-eye in a geologic instant.
This is all based upon one big assumption: that biological tissues are innately plastic. Little attention is given to the biochemical and molecular conundrums which confront such scenarios. In other words, all that we have learned in the last 50 years of genetics and biochemistry is totally ignored. One cannot help but wonder whether the details of biochemistry are ignored as a result of oversight or whether it is, rather, because it presents such a formidable challenge to conventional evolutionary explanations that to pay it due attention would radically undermine the Darwinian paradigm.

Lamb's choice of words in the above seems to imply a spontaneous embryological development of the lens, and he suggests that perhaps evolution happened in much the same manner. The problem is that lens formation does not, in reality, possess such spontaneity -- far from it. Rather, it is triggered by the release of several chemicals, called "inducers," from the optic vesicle. In epithelial cells, release of these chemicals triggers the expression of the genes which are involved in implementing lens development. The inducer triggers the epithelial cells to start producing a transcription factor, which is often called the "master control gene" of eye development (known as Pax6). Pax6 subsequently activates the genes that cause the epithelium to form a lens placode and then a lens vesicle.

Pax6 also plays a role in the initial formation of the optic vesicle, and in differentiation of retinal cells. This gives rise to an interesting question -- how does the same transcription factor perform different roles in different cell types? Its action is carefully modulated by an array of other factors which are particular to the respective tissues and cell types. In the case of epithelial cells, Pax6 works in collaboration with another transcription factor called Sox2. When these two proteins bind together on a specific DNA sequence, it literally acts as a genetic switch -- triggering lens differentiation.

As Lamb himself explains, lens morphogenesis results from "a thickening of the embryo's outer surface, or ectoderm, that bulges into the curved empty space formed by the C-shaped retina. This protrusion eventually separates from the rest of the ectoderm to become a free-floating element."

The lens vesicle subsequently morphs into a lens. The cells of the vesicle's posterior wall become lens fibers, which grow substantially to a length dozens of times greater than their original size (meaning they completely cover the vesicle cavity). There are several important changes which these cells need to undergo in order to take up their role as lens fibers. For one thing, they have to lose their internal organelles to allow the incoming light to be successfully transmitted through them. The lens fibers are also packed very tightly together -- hexagonal in cross-section, and aligned parallel to the axis of the eye.

These lens fibers also produce proteins known as crystallins, and Pax6 (the transcription factor which I mentioned previously) is involved in activating the crystallin genes. The high level of production of these proteins confers an extraordinary high density and hence a high refractive index which is responsible for the lens' light-bending properties.

Now, at this point we potentially run into a problem.

In the case of most proteins, if they accumulated in such a high concentration as this, they would have a tendency to agglomerate and denature. This would entail that the lens would become cloudy and thus lose its transparency. The proteins which are used -- crystallins -- however, are exceptionally stable, and the largest class of these proteins actually serves to stabilise the other crystallins. This class is known as α-crystallin, and these molecules interact to form hollow balls which are connected by other proteins called CP49 and filensin. This forms a structure called a "beaded filament". These structures predominate within the lens fibers. They are absolutely critical for facilitating such a dense concentration of proteins to actually enhance visual capabilities. Even more remarkable is the fact that these proteins are never recycled. Unlike most other proteins, these crystallin molecules do not degrade and thereby result in the lens becoming cloudy. The beaded filament structures actually protect the proteins from such degradation and denaturation. Actually, one of the causes of eye cataracts is a faulty beaded filament structure.

But here's the bottom line: This is not the type of system which one might intuitively expect to be the product of trial-and-error Darwinian-type tinkering. To simply appeal to the addition of a lens is to fundamentally trivialise the matter at hand.

Chicken And Egg
I have really only scratched the surface here. Molecular morphogenesis of the eye extends far deeper than this. Once the optic vesicle has contacted the epithelium, it spreads outwards and folds in on itself. This forms the hollow eyeball. The inner layer of this will develop into the retina. What is particularly remarkable is that, while the optic vesicle is absolutely fundamental for the induction of lens development, subsequent development of the eye depends, in large measure, on factors which are secreted by the developing lens! This casts even further doubt on the sorts of scenarios commonly offered to us by Darwinians such as Lamb, wherein the lens is viewed as a relatively late addition to the eye structure.

Further Problems
In his review of Richard Dawkins' Climbing Mount Improbable, David Berlinski makes the following additional observations:

Light strikes the eye in the form of photons, but the optic nerve conveys electrical impulses to the brain. Acting as a sophisticated transducer, the eye must mediate between two different physical signals. The retinal cells that figure in Dawkins' account are connected to horizontal cells; these shuttle information laterally between photoreceptors in order to smooth the visual signal. Amacrine cells act to filter the signal. Bipolar cells convey visual information further to ganglion cells, which in turn conduct information to the optic nerve. The system gives every indication of being tightly integrated, its parts mutually dependent.
The very problem that Darwin's theory was designed to evade now reappears. Like vibrations passing through a spider's web, changes to any part of the eye, if they are to improve vision, must bring about changes throughout the optical system. Without a correlative increase in the size and complexity of the optic nerve, an increase in the number of photoreceptive membranes can have no effect. A change in the optic nerve must in turn induce corresponding neurological changes in the brain. If these changes come about simultaneously, it makes no sense to talk of a gradual ascent of Mount Improbable. If they do not come about simultaneously, it is not clear why they should come about at all.

The same problem reappears at the level of biochemistry. Dawkins has framed his discussion in terms of gross anatomy. Each anatomical change that he describes requires a number of coordinate biochemical steps. "[T]he anatomical steps and structures that Darwin thought were so simple," the biochemist Mike Behe remarks in a provocative new book (Darwin's Black Box), "actually involve staggeringly complicated biochemical processes." A number of separate biochemical events are required simply to begin the process of curving a layer of proteins to form a lens. What initiates the sequence? How is it coordinated? And how controlled? On these absolutely fundamental matters, Dawkins has nothing whatsoever to say.

Is The Vertebrate Eye Bad Design?
Lamb tells us that,
The vertebrate eye, far from being intelligently designed, contains numerous defects that attest to its evolutionary origin. Some of these flaws degrade image quality, including an inside-out retina that focus light to pass through cell bodies and nerve bodies before hitting the photoreceptors; blood vessels that sprawl across the retina's inner surface, casting undesirable shadows onto the retina; nerve fibers that gather together to push through a single opening in the retina to become the optic nerve, creating a blind spot.
This argument has been addressed many a time. The bottom line is this: Retinal cells require a very large oxygen supply, and hence a very large blood supply. Blood cells absorb light. If blood cells invade retinal cells, the consequence can be blindness. This entails that the retinal cells need to receive a blood supply from vessels which do not block the light. Since red blood cells readily absorb light, this demand requires that the retina be wired in the manner in which it is. As is often pointed out, squids and octopuses have 'correctly' wired retinas that face outward. But these organisms are exothermic -- they do not require the same blood supply to the retina.

For a slightly different perspective on this topic, I refer readers to Richard Sternberg's essay here.

Summary and Conclusions

I have only provided a sketchy overview of a few of the key processes which undergird eye development. I have not even discussed the biochemical and molecular details of vision (for that, I refer readers to Michael Behe's book, Darwin's Black Box, or this article). In addition, Casey Luskin has an excellent critique of the Darwinian account of the eye's origin here. Nonetheless, I hope that this article has given readers a sense for why Darwinists are going to have to do a lot better than they are currently doing if they are to convince us of the plausibility of their model.

I.D as pure science

Defining and Utilizing Intelligent Design in Science
Kirk Durston November 5, 2015 10:21 AM


My introduction to the role of intelligent design (ID) detection in science was a student job in the summer of 1978 working for National Defense Research. My assignment was to write software that could detect Soviet submarines amid the natural background noise of the ocean. I successfully completed the project by utilizing, among other things, a fast Fourier transform applied to the signals from underwater acoustic microphones. The otherwise hidden target signal stood out like a sore thumb.

After graduating with degrees in physics and in mechanical engineering, I spent a few years working as a test engineer, helping to coordinate the build and test of experimental aircraft engines for a major company. During that time, I had the opportunity to interact with different departments, including Design. I could see how a new model of aircraft engine emerged, beginning with an idea in an intelligent mind, which was then encoded into prescriptive information and culminated in a novel, fully functional turbine engine. It was ID in action.

In science, it is essential to define what one is talking about when referring to ID. In my own view it can be defined as follows:

Intelligent Design: an effect that requires an intelligent mind to produce

Examples include the unique acoustic signature of a submarine, a smartphone, the fitness function of a well-designed genetic algorithm, and an artificial protein.

I was invited to consider doing a PhD in Bioinformatics at the University of Guelph. On the condition that my research would focus on the role of information encoded in biopolymers, I applied and was accepted into the Biophysics Masters program with the understanding that if my academic performance was "outstanding" (their term -- and I mention this only to protect the academic integrity of my alma mater), I might be permitted to transfer into a PhD program after the first year. Twelve months later the Biophysics department gave the go-ahead to complete a PhD program.

The first project was to develop a method to measure the minimum level of functional information required to code for a protein family. The results were published, and I then moved on to my first major ID-inspired project. As a result of my experience in testing experimental aircraft engines I observed that an intelligent designer usually specifies a higher degree of information for interdependent components. What if I applied this ID observation to the functional information encoding the 3D structure of globular proteins? My prediction was that it should reveal interdependencies within the primary structure. This, in turn, would reveal key sub-molecular structural components within the larger 3D structure.

To test this hypothesis and prediction, I ran a large multiple sequence alignment for ubiquitin through a pattern discovery program that searched for patterns of high information content between sites in the sequence, and clustered the sites accordingly in a nested hierarchy. I was thrilled when the results revealed a cluster tree that predicted important structural interdependencies as well as key binding areas and possible stages of the folding sequence. Comparison with the known 3D structure for ubiquitin, together with published research on binding areas and unfolding experiments, confirmed that the results were meaningful. These were published in a subsequent paper. This approach could give rise to an enormous ID-inspired research program that would give further understanding into protein structure and folding, should someone decide to pursue it.

I have observed three ways in which ID is firmly entrenched in science:

Design Application: The application of intelligence to first principles of physics to produce a desired effect. (e.g., artificial proteins)

Design Derivation: Beginning with a complex effect, the process of reverse engineering back to first principles in an effort to understand the design and how it works (e.g., genetics is probably the largest reverse engineering/ID project that science has embarked upon).

Design Detection: The analysis of an effect to determine if it requires an intelligent mind (e.g., marking and identification of artificial genomes, proteins and designer drugs, as well as forensic science, archeology, decryption and SETI).

The application of these three areas gives rise to a number of predictions in science, which I will deal with in other posts.

The role of ID in science continues to intrigue me, especially design detection. Over the years, I noticed that wherever there were statistically significant levels of functional information, there was an intelligent mind not far away.

How does one develop a method in science to detect when ID is required? I have observed that different disciplines in science use a variety of approaches. However, I realized there was a hypothesis that could provide a common solution to all design detection problems. Despite the variety of approaches used in forensic science, archeology, SETI, and biology, the core of each method could be reduced to just one, generally assumed hypothesis, which I call the central hypothesis:

Central hypothesis: A unique attribute of an intelligent mind is the ability to produce statistically significant levels of functional information (If).

This hypothesis is testable, falsifiable, verifiable, and provides the basis for a scientific method for design detection as follows:

Step One: Measure the minimum level of If required to produce the effect.

Step Two: Determine if the level of If is statistically significant.

Step Three: If If is statistically significant, the artifact/signal/effect tests positive for ID.


In the future, I hope to discuss an application of this method for design detection in science, together with its implication for the protein families of biology.

Vasoconstriction and Platelet Aggregation Defy Evolutionary Explanations


Darwinism Vs. The real world XVIII

Blood Clotting Requires Four Different Processes Working Together
Howard Glicksman October 26, 2015 4:17 AM

Editor's note: Physicians have a special place among the thinkers who have elaborated the argument for intelligent design. Perhaps that's because, more than evolutionary biologists, they are familiar with the challenges of maintaining a functioning complex system, the human body. With that in mind, Evolution News & Views is delighted to present this series, "The Designed Body." For the complete series, see here. Dr. Glicksman practices palliative medicine for a hospice organization.

Let's review some of the lessons that this series has so far provided about human life. The body is made up of trillions of cells, each of which must control its volume and chemical content while receiving what it needs from the blood to live, grow, and work properly. Since the body is made up of matter, it is subject to the laws of nature, which demand that it have enough energy to do what it needs to do to survive.

The body must constantly take in oxygen through the respiratory system to provide itself with the energy it needs to live because, unlike glucose, oxygen can't be stored for future use. About one-quarter to one-half of the energy the body uses while at rest is just for the sodium-potassium pumps within the plasma membrane of its trillions of cells. These pumps push Na+ ions out of the cell and bring K+ ions back in. This action not only maintains the volume and chemical content of the cell, but also the 2/3:1/3 ratio of water inside and outside the cells.

Combined with the control of its water and sodium content and the production of albumin, this process allows the body to maintain enough blood volume. The sodium-potassium pumps also maintain the electrical resting membrane potential of the cell. This is particularly important for proper heart, nerve, and muscle function.

When the cells in the brainstem die (the ones that tell the body to breathe, control its circulation, and make it conscious of its surroundings) the body is considered dead. However, the commonest cardiopulmonary arrest is the most common cause of death. Without respiration the body can't bring in new supplies of oxygen and get rid of toxic carbon dioxide, and without the heart pumping, there isn't enough blood flow to the brain. Together, this causes it to malfunction.

Since blood has mass, the heart has to pump it throughout the body against natural forces like inertia, friction and gravity that would prevent it from moving. As blood moves through the circulatory system, it applies a pressure against the vessel walls. This represents the energy that is generating its flow.

In clinical practice, the blood pressure is taken in the upper arm and is a measure of the force of blood against the walls of the brachial artery. The blood pressure is dependent on how well the heart pumps, how much blood is in the systemic arteries, and the resistance to blood flow applied by the downstream arterioles that control how much blood enters the capillaries. Blood flow (Q) is directly related to the blood pressure (P) and inversely related to the vascular resistance (R). This law of nature can be expressed as Q = P/R. The more blood pressure the more blood flow and the less blood pressure the less blood flow. The more vascular resistance the less blood flow and the less vascular resistance the more blood flow.

When we stand up and feel momentarily dizzy, our body must inherently know that if Q = P/R, then P = Q x R. In other words, blood pressure is directly related to the blood flow and vascular resistance. More blood flow and vascular resistance increases the blood pressure and less blood flow and vascular resistance decreases the blood pressure.

Standing up allows gravity to prevent blood from returning to the heart from the veins in the chest, abdomen and legs. It also keeps it from going from the heart to the brain, which reduces the blood pressure and blood flow to the brain. That's what makes us feel dizzy. The body detects these changes and reacts by sending out nerve messages to make the heart pump harder and faster, pushes blood from the veins back toward the hear,t and increases the vascular resistance applied by the arterioles by increasing the contraction of their surrounding muscles. The first two actions increase blood flow (Q) and the last one increases the vascular resistance (R), so the blood pressure (P) rises and our dizziness usually resolves in a matter of seconds.

The above demonstrates just some of the ways the body takes control and follows the rules in line with the Goldilocks principle: the real numbers must be "just right." After all, life doesn't take place within a vacuum or the imaginations of evolutionary biologists. As was the case with our earliest ancestors, to survive we must remain active, exposing our body, and our blood vessels, to the random forces of nature.

Experience tell us that when we run, jump, climb, roll, fall, and generally bang into or scrape up against solid or sharp things, natural forces like friction, momentum, pressure, sheer and gravity all contribute to blood vessel damage, bleeding and blood loss. This takes place because, with damage to the blood vessel wall, the pressure that sustains blood flow within it naturally pushes blood out through the opening. Think of it like when a water pipe in your home bursts. The water flowing through it is under pressure and when the walls of the pipe rupture water naturally flows out. Depending on the location and the severity, if the body can't stop the bleeding fast enough it runs the risk of serious problems. So to follow the rules that the laws of nature impose on it, the body must have a mechanism in place to prevent excessive bleeding from its blood vessels when they undergo injury.

Experience teaches that when we cut ourselves, a clot forms at the injured site to stop the bleeding and allow healing to take place over the next several days. This process is called hemostasis (Greek: haima = blood + stasis = halt).

Hemostasis generally involves three actions that occur almost simultaneously. Vasoconstriction is contraction of the muscles surrounding the injured blood vessel, which tries to totally close down the opening in the wall. Platelet aggregation is the formation of a soft plug by the platelets coming together and sticking to each other to fill the gap in the blood vessel wall. And activation of the clotting factors is the formation of thousands of sticky strands of fibrin which wrap around the platelet plug to form a molecular meshwork that entraps red blood cells and plasma to form a fibrin clot which closes off the damage and stops the bleeding.

However, when it comes to preventing blood loss from blood vessel injury through hemostasis, the laws of nature present the body with another dilemma. It's important that the clotting mechanism turn on only when it's needed, not only to not waste the body's supply of platelets and clotting factors, but also to prevent the sudden blockage of blood flow to vital organs. A poorly placed blood clot within an artery supplying blood to the heart muscle can cause a heart attack, or to the brain, a stroke, or to the lungs, a sudden drop in oxygen availability. Any one of these situations can result in serious and permanent debility or sudden death.


So, in addition to being able to turn on at the right time, the body must also have a mechanism in place to take control so that hemostasis will turn off and stay off at the right times. How does the body do it and how does evolutionary biology explain how it works in real life? That's what we'll begin to look at next time.
