    Alexander Tsiaras: Conception to birth — visualized – video
    http://www.youtube.com/watch?v=fKyljukBE70
    Comment on preceding video: Mathematician and medical image maker Alexander Tsiaras offers a stunning visualization of the process that in nine months takes an emerging human life from conception to birth. He speaks of “the marvel of this information,” “the mathematical models of how these things are done are beyond human comprehension,” “even though I look at this with the eyes of mathematician I look at this and marvel. How do these instruction sets not make mistakes as they build what is us?”

    How many different cells are there in complex organisms?
    Excerpt: The nematode worm Caenorhabditis elegans, the cellular ontogeny of which has been precisely mapped, has 1,179 and 1,090 distinct somatic cells (including those that undergo programmed cell death) in the male and female, respectively, each with a defined history and fate. Therefore, if we take the developmental trajectories and cell position into account, C. elegans has 10^3 different cell identities, even if many of these cells are functionally similar. By this reasoning, although the number of different cell types in mammals is often considered to lie in the order of hundreds, it is actually in the order of 10^12 if their positional identity and specific ontogeny are considered. Humans have an estimated 10^14 cells, mostly positioned in precise ways and with precise organization, shape and function, in skeletal architecture, musculature and organ type, many of which (such as the nose) show inherited idiosyncrasies. Even if the actual number of cells with distinct identities is discounted by a factor of 100 (on the basis that 99% of the cells are simply clonal expansions of a particular cell type in a particular location or under particular conditions (for example, fat, muscle or immune cells)), there are still 10^12 positionally different cell types.

    The following simple experiment clearly reveals that the reductive materialism of neo-Darwinism cannot be the explanation for the ‘form’ of an organism

    HOW BIOLOGISTS LOST SIGHT OF THE MEANING OF LIFE — AND ARE NOW STARING IT IN THE FACE – Stephen L. Talbott – May 2012
    Excerpt: The same sort of question can be asked of cells, for example in the growing embryo, where literal streams of cells are flowing to their appointed places, differentiating themselves into different types as they go, and adjusting themselves to all sorts of unpredictable perturbations — even to the degree of responding appropriately when a lab technician excises a clump of them from one location in a young embryo and puts them in another, where they may proceed to adapt themselves in an entirely different and proper way to the new environment. It is hard to quibble with the immediate impression that form (which is more idea-like than thing-like) is primary, and the material particulars subsidiary.

    Another clear indication that the reductive materialism of neo-Darwinism cannot be the explanation for the form of a organism is given by realizing that the ‘form’ of an organism is semi-immediately lost upon the death of an organism:

    The Unbearable Wholeness of Beings – Stephen L. Talbott
    Excerpt: Virtually the same collection of molecules exists in the canine cells during the moments immediately before and after death. But after the fateful transition no one will any longer think of genes as being regulated, nor will anyone refer to normal or proper chromosome functioning. No molecules will be said to guide other molecules to specific targets, and no molecules will be carrying signals, which is just as well because there will be no structures recognizing signals. Code, information, and communication, in their biological sense, will have disappeared from the scientist’s vocabulary.
    ,,, the question, rather, is why things don’t fall completely apart — as they do, in fact, at the moment of death. What power holds off that moment — precisely for a lifetime, and not a moment longer?
    Despite the countless processes going on in the cell, and despite the fact that each process might be expected to “go its own way” according to the myriad factors impinging on it from all directions, the actual result is quite different. Rather than becoming progressively disordered in their mutual relations (as indeed happens after death, when the whole dissolves into separate fragments), the processes hold together in a larger unity.

    Seeing the Natural World With a Physicist’s Lens – November 2010
    Excerpt: Scientists have identified and mathematically anatomized an array of cases where optimization has left its fastidious mark, among them;,, the precision response in a fruit fly embryo to contouring molecules that help distinguish tail from head;,,, In each instance, biophysicists have calculated, the system couldn’t get faster, more sensitive or more efficient without first relocating to an alternate universe with alternate physical constants.
    http://www.nytimes.com/2010/11.....038;st=cse

    Moreover, Dr. Wells has shown that this optimal, ‘relocate to an alternate universe’, embryonic development depends on ‘Pre-existing Spatial Coordinates’ that are not reducible to DNA sequences as is postulated in the modern synthesis of neo-Darwinism

    Gene Regulatory Networks in Embryos Depend on Pre-existing Spatial Coordinates – Jonathan Wells – July 2011
    Excerpt: The development of metazoan embryos requires the precise spatial deployment of specific cellular functions. This deployment depends on gene regulatory networks (GRNs), which operate downstream of initial spatial inputs (E. H. Davidson, Nature 468 [2010]: 911). Those initial inputs depend, in turn, on pre-existing spatial coordinate systems. In Drosophila oocytes, for example, spatial localization of the earliest-acting elements of the maternal GRN depends on the prior establishment of an anteroposterior body axis by antecedent asymmetries in the ovary. Those asymmetries appear to depend on cytoskeletal and membrane patterns rather than on DNA sequences,,,
    http://www.discovery.org/scrip.....38;id=7751

    And indeed, experimental evidence shows that no matter what researchers do to sequences of DNA. they are unable to alter the basic body plan of a fruit fly (or any other creature) in any radical way:

    ‘No matter what we do to a fruit fly embryo there are only three possible outcomes, a normal fruit fly, a defective fruit fly, or a dead fruit fly. What we never see is primary speciation much less macro-evolution’ –

    Darwin’s Theory – Fruit Flies and Morphology – video
    http://www.youtube.com/watch?v=hZJTIwRY0bs

    …Advantageous anatomical mutations are never observed. The four-winged fruit fly is a case in point: The second set of wings lacks flight muscles, so the useless appendages interfere with flying and mating, and the mutant fly cannot survive long outside the laboratory. Similar mutations in other genes also produce various anatomical deformations, but they are harmful, too. In 1963, Harvard evolutionary biologist Ernst Mayr wrote that the resulting mutants “are such evident freaks that these monsters can be designated only as ‘hopeless.’ They are so utterly unbalanced that they would not have the slightest chance of escaping elimination through natural selection.” –
    Jonathan Wells

    Response to John Wise – October 2010
    Excerpt: A technique called “saturation mutagenesis”1,2 has been used to produce every possible developmental mutation in fruit flies (Drosophila melanogaster),3,4,5 roundworms (Caenorhabditis elegans),6,7 and zebrafish (Danio rerio),8,9,10 and the same technique is now being applied to mice (Mus musculus).11,12 None of the evidence from these and numerous other studies of developmental mutations supports the neo-Darwinian dogma that DNA mutations can lead to new organs or body plans–because none of the observed developmental mutations benefit the organism.
    per evolution news and views

    This body plans are not reducible to mutations to DNA is certainly not a minor problem for neo-Darwinists. As Dr. Meyer puts it in the following video, the neo-Darwinian mechanism is ‘grossly inadequate to explain the origination of novel biological form.’

    Stephen Meyer – Functional Proteins and Information for Body Plans – video
    https://vimeo.com/91322260

    Dr. Stephen Meyer comments at the end of the preceding video,,,
    ‘Now one more problem as far as the generation of information. It turns out that you don’t only need information to build genes and proteins, it turns out to build Body-Plans you need higher levels of information; Higher order assembly instructions. DNA codes for the building of proteins, but proteins must be arranged into distinctive circuitry to form distinctive cell types. Cell types have to be arranged into tissues. Tissues have to be arranged into organs. Organs and tissues must be specifically arranged to generate whole new Body-Plans, distinctive arrangements of those body parts. We now know that DNA alone is not responsible for those higher orders of organization. DNA codes for proteins, but by itself it does not insure that proteins, cell types, tissues, organs, will all be arranged in the body. And what that means is that the Body-Plan morphogenesis, as it is called, depends upon information that is not encoded on DNA. Which means you can mutate DNA indefinitely. 80 million years, 100 million years, til the cows come home. It doesn’t matter, because in the best case you are just going to find a new protein some place out there in that vast combinatorial sequence space. You are not, by mutating DNA alone, going to generate higher order structures that are necessary to building a body plan. So what we can conclude from that is that the neo-Darwinian mechanism is grossly inadequate to explain the origin of information necessary to build new genes and proteins, and it is also grossly inadequate to explain the origination of novel biological form.
    Stephen Meyer – (excerpt taken from Meyer/Sternberg vs. Shermer/Prothero debate – 2009)

    In this following excerpt from his book Darwin’s Doubt, Dr. Meyer states that ‘genetic mutations are simply the wrong tool for the job at hand.’:

    “These different sources of epigenetic information in embryonic cells pose an enormous challenge to the sufficiency of the neo-Darwinian mechanism. According to neo-Darwinism, new information, form, and structure arise from natural selection acting on random mutations arising at a very low level within the biological hierarchy—within the genetic text. Yet both body-plan formation during embryological development and major morphological innovation during the history of life depend upon a specificity of arrangement at a much higher level of the organizational hierarchy, a level that DNA alone does not determine. If DNA isn’t wholly responsible for the way an embryo develops—for body-plan morphogenesis—then DNA sequences can mutate indefinitely and still not produce a new body plan, regardless of the amount of time and the number of mutational trials available to the evolutionary process. Genetic mutations are simply the wrong tool for the job at hand.
    Stephen Meyer – Darwin’s Doubt (p. 281)

    Of related interest to highly sophisticated developmental Gene Regulatory Networks (dGRN)controlling embryonic development, and the inability of mutations to DNA to radically alter basic body plans, is this debate that Dr. Meyer had with Charles Marshall on ‘Unbelievable’ Christian radio:

    Supplemental note: The human body consists. conservatively, of something like a billion, trillion, protein molecules:

    HOW BIOLOGISTS LOST SIGHT OF THE MEANING OF LIFE — AND ARE NOW STARING IT IN THE FACE – Stephen L. Talbott – May 2012
    Excerpt: “If you think air traffic controllers have a tough job guiding planes into major airports or across a crowded continental airspace, consider the challenge facing a human cell trying to position its proteins”. A given cell, he notes, may make more than 10,000 different proteins, and typically contains more than a billion protein molecules at any one time. “Somehow a cell must get all its proteins to their correct destinations — and equally important, keep these molecules out of the wrong places”. ,,,
    The question is indeed, then, “How does the organism meaningfully dispose of all its molecules, getting them to the right places and into the right interactions?”
    The same sort of question can be asked of cells, for example in the growing embryo, where literal streams of cells are flowing to their appointed places, differentiating themselves into different types as they go, and adjusting themselves to all sorts of unpredictable perturbations ,,,
    “The human body is formed by trillions of individual cells. These cells work together with remarkable precision, first forming an adult organism out of a single fertilized egg, and then keeping the organism alive and functional for decades.,,,
    And then we hear that all this meaningful activity is, somehow, meaningless or a product of meaninglessness. This, I believe, is the real issue troubling the majority of the American populace when they are asked about their belief in evolution. They see one thing and then are told, more or less directly, that they are really seeing its denial. Yet no one has ever explained to them how you get meaning from meaninglessness — a difficult enough task once you realize that we cannot articulate any knowledge of the world at all except in the language of meaning.,,,
    http://www.netfuture.org/2012/May1012_184.html#2

    If, to be an atheist, I have to believe that a billion, trillion, protein molecules, all directed towards the goal of keeping a person alive, is the result of purely undirected’, processes, then I simply do not have enough faith to be an atheist. It is far beyond unreasonable to believe as such. In fact, I consider it delusional to believe as such.
