We’re not sure. From ScienceDaily:

As cells divide to form tissues and organs in multicell organisms, they move to where they belong, informed by a series of cues that scientists have yet to observe or fully understand.
These collective movements traditionally have been studied in the context of biochemical recognition between cell types. For example, the protein cadherin (found in, and named for, calcium dependent adhesions) is one element responsible for cells’ ability to recognize one another, with various types of cadherin occurring at different sites in the organism. These cadherin receptors enable like cells to combine with each other to build specific types of tissue; for example, E-cadherin is so named because it is found in epithelial cells.
“Cadherins provide an initial signal for the ‘handshake’ between cells, but they are not the primary keeper of the connection,” says UC Santa Barbara professor and mechanical engineer Beth Pruitt, who studies mechanobiology and is working to gain a greater understanding of how cells combine to form tissues and maintain their integrity under the normal loads they experience …
As cells slide past each other while migrating toward their destinations during development or wound healing, they exert shear forces. Exactly how these local in-plane shear forces are spread throughout a tissue — important in collective tissue behavior — is not understood, in part because it is difficult to apply direct, localized shear within a tissue…
“Through observing these oscillations and measuring overall forces, as enabled by the inline spring, we were able to put forward a mechanical model that includes a mechanical signal-storage-and-relay element for simulating epithelial cell monolayers,” Pruitt explained. “This element, in parallel with the cells’ well-known viscoelastic property, can account for the collective behavior we observed. Cells might utilize this behavior following a shear-induced force imbalance to maintain tension homeostasis within a developing tissue.” Paper. (open access) – Ehsan Sadeghipour, Miguel A Garcia, William James Nelson, Beth L Pruitt. Shear-induced damped oscillations in an epithelium depend on actomyosin contraction and E-cadherin cell adhesion. eLife, 2018; 7 DOI: 10.7554/eLife.39640 More.

While the researchers don’t, of course, come right out and say this, massive communications exist within each cell, whether of a mouse, a grapevine, or a human. And we really don’t know very much about it at all. Yet many presume to insist that such structures arose randomly as a result of natural selection acting on random mutation (Darwinism), which cannot possibly be true. If it were, strange things would be happening all over the place. Yet they are not.

Is it just imagination or do people increasingly write in such a way as to simply abandon the pretense without wanting to discuss it?

Didn't Meyer say in his book that there were instructions that were in the cell wall and there was a different information system completely unlike DNA etc. What happened to that? Has it been debunked? It was a different form of epigenetic information. He mentioned something called the sugar code. He had a chapter on the Origin of Body Plans in Darwin's Doubt followed by one on Epigenetic effects. One thought was if you are going to make major changes in an organism it would have to be in what generated body plans and it would have to act early in the gestation process. But early changes are most likely to cause organism failure if a mutation happens.jerry_{January 17, 2019

Of related interest to the question of 'How Do Cells In A Body Know Where They Are Supposed To Be?" is the following, ""When a frog embryo is just developing, before it gets a face, a pattern for that face lights up on the surface of the embryo."
The (Electric) Face of a Frog - video https://www.youtube.com/watch?v=0VULjzX__OM Timelapse Video Reveals Electric Face in Embryonic Tadpole - July 2011 Excerpt: "When a frog embryo is just developing, before it gets a face, a pattern for that face lights up on the surface of the embryo. We believe this is the first time such patterning has been reported for an entire structure, not just for a single organ. I would never have predicted anything like it. It's a jaw dropper." http://www.sciencespacerobots.com/timelapse-video-reveals-electric-face-in-embryonic-tadpole-718111
As Dr. Hunter states, "The video suggests that bioelectric signals presage the morphological development of the face."
An Electric Face: A Rendering Worth a Thousand Falsifications – Cornelius Hunter - September 2011 Excerpt: The video suggests that bioelectric signals presage the morphological development of the face. It also, in an instant, gives a peak at the phenomenal processes at work in biology. As the lead researcher said, “It’s a jaw dropper.” http://darwins-god.blogspot.com/2011/09/electric-face-rendering-worth-thousand.html
Moreover, altering the bio-electric field without altering the underlying molecules affects the three-dimensional shape of the developing embryo.
podcast - Dr. Jonathan Wells explains the concept of codes in living things, and how they affect the debate over neo-Darwinism and intelligent design. (at least 5 different codes outside of DNA are discussed) - Oct. 2015 – 4:45 minute mark 5.Bio-electric code – altering the bio-electric field without altering the underlying molecules affects the three-dimensional shape of the developing embryo http://www.discovery.org/multimedia/audio/2015/10/id-inquiry-jonathan-wells-on-codes-in-biology/#more-31141
In the case of frog embryos, "artificially setting other somatic cells to the eye-specific voltage range resulted in formation of eyes in aberrant locations, including tissues that are not in the normal anterior ectoderm lineage: eyes could be formed in the gut, on the tail, or in the lateral plate mesoderm.
Cracking the bioelectric code: Probing endogenous ionic controls of pattern formation - January 2013 Excerpt: A recent paper demonstrated that a specific voltage range is necessary for demarcation of eye fields in the frog embryo. Remarkably, artificially setting other somatic cells to the eye-specific voltage range resulted in formation of eyes in aberrant locations, including tissues that are not in the normal anterior ectoderm lineage: eyes could be formed in the gut, on the tail, or in the lateral plate mesoderm. These data challenge the existing models of eye fate restriction and tissue competence maps, and suggest the presence of a bioelectric code-a mapping of physiological properties to anatomical outcomes. http://www.ncbi.nlm.nih.gov/pubmed/23802040
To date, no one knows how the bioelectric code is 'supposedly' encoded within the developing embryo:
The bioelectric code: An ancient computational medium for dynamic control of growth and form. - 2017 Excerpt: We review emerging progress in reading and re-writing anatomical information encoded in bioelectrical states, and discuss the approaches to this problem from the perspectives of information theory, dynamical systems, and computational neuroscience. Cracking the bioelectric code will enable much-improved control over biological patterning, advancing basic evolutionary developmental biology as well as enabling numerous applications in regenerative medicine and synthetic bioengineering. https://www.ncbi.nlm.nih.gov/pubmed/28855098 The Bioelectric Code: Reprogramming Cancer and Aging From the Interface of Mechanical and Chemical Microenvironments - March 2018 Excerpt: there is considerable interest in manipulating Vm both to treat cancer as well as to regenerate organs damaged or deteriorated during aging. However, such manipulations have produced conflicting outcomes experimentally, which poses a substantial barrier to understanding the fundamentals of bioelectrical reprogramming. https://www.frontiersin.org/articles/10.3389/fcell.2018.00021/full

Moreover, we have fairly strong evidence indicating that this enormous amount of positional information, that is telling all these atoms of the developing embryo exactly where to be, is somehow coming into the developing embryo from outside the material realm. For instance, at about the 41:00 minute mark of the following video, Dr. Wells, using a branch of mathematics called category theory, demonstrates that, during embryological development, information must somehow be added to the developing embryo, ‘from the outside’, by some ‘non-material’ method.
Design Beyond DNA: A Conversation with Dr. Jonathan Wells – video (41:00 minute mark) – January 2017 https://youtu.be/ASAaANVBoiE?t=2484
The following article adds weight to Dr Wells assessment and states: "the process of development should be thought of as being controlled by an “algebraic structure outside space-time itself”
Intelligent Design and the Advancement of Science - Brian Miller - December 11, 2017 Excerpt: DNA was expected to be the primary source of causality behind the operation and development of life. Such beliefs have previously raised concerns from leading scientists and mathematicians. For instance, physicist Walter Elsasser argued that the unfathomable complexity of the chemical and physically processes in life was “transcomputational” — beyond the realm of any theoretical means of computation. Moreover, the development of the embryo is not solely directed by DNA. Instead, it requires new “biotonic” principles. As a result, life cannot be reduced to chemistry and physics. An unbridgeable gap separates life from non-life. Similarly, mathematician René Thom argued that the 3D patterns of tissues in an organism’s development from egg to birth and their continuous transformation cannot be understood in terms of isolating the individual proteins generated by DNA and other molecules produced in cells. The problem is that the individual “parts” composing tissues and organs only take on the right form and function in the environment of those tissues and organs. More recent work by Denis Noble further has elucidated how every level of the biological hierarchy affects every other level, from DNA to tissues to the entire organism. Based partly on these insights, Thom concluded in his book Structural Stability and Morphogenesis that the process of development should be thought of as being controlled by an “algebraic structure outside space-time itself” (p. 119). Likewise, Robert Rosen argued that life can only be understood as a mathematical abstraction consisting of functional relationships, irreducible to mechanistic processes. He observed that life is fundamentally different from simple physics and chemistry. It embodies the Aristotelian category of final causation, which is closely related to the idea of purpose. The conclusions of these scholars challenge materialistic philosophy at its core. https://evolutionnews.org/2017/12/intelligent-design-and-the-advancement-of-science/
To provide further evidence for information coming into the developing embryo from ‘outside space-time itself’, it is important to note that quantum correlations somehow arise from outside spacetime, in the sense that no story in space and time can describe them,,,
Looking beyond space and time to cope with quantum theory – 29 October 2012 Excerpt: “Our result gives weight to the idea that quantum correlations somehow arise from outside spacetime, in the sense that no story in space and time can describe them,” http://www.quantumlah.org/highlight/121029_hidden_influences.php
And these quantum correlations which somehow arise from outside spacetime, are now found in molecular biology on a massive scale. In every DNA and Protein molecule,,,
"What happens is this classical information (of DNA) is embedded, sandwiched, into the quantum information (of DNA). And most likely this classical information is never accessed because it is inside all the quantum information. You can only access the quantum information or the electron clouds and the protons. So mathematically you can describe that as a quantum/classical state." Elisabeth Rieper – Classical and Quantum Information in DNA – video (Longitudinal Quantum Information resides along the entire length of DNA discussed at the 19:30 minute mark; at 24:00 minute mark Dr Rieper remarks that practically the whole DNA molecule can be viewed as quantum information with classical information embedded within it) https://youtu.be/2nqHOnVTxJE?t=1176 Quantum coherent-like state observed in a biological protein for the first time - October 13, 2015 Excerpt: If you take certain atoms and make them almost as cold as they possibly can be, the atoms will fuse into a collective low-energy quantum state called a Bose-Einstein condensate. In 1968 physicist Herbert Fröhlich predicted that a similar process at a much higher temperature could concentrate all of the vibrational energy in a biological protein into its lowest-frequency vibrational mode. Now scientists in Sweden and Germany have the first experimental evidence of such so-called Fröhlich condensation (in proteins).,,, The real-world support for Fröhlich's theory took so long to obtain because of the technical challenges of the experiment, Katona said. https://phys.org/news/2015-10-quantum-coherent-like-state-biological-protein.html Quantum criticality in a wide range of important biomolecules – Mar. 6, 2015 Excerpt: “Most of the molecules taking part actively in biochemical processes are tuned exactly to the transition point and are critical conductors,” they say. That’s a discovery that is as important as it is unexpected. “These findings suggest an entirely new and universal mechanism of conductance in biology very different from the one used in electrical circuits.” The permutations of possible energy levels of biomolecules is huge so the possibility of finding even one (biomolecule) that is in the quantum critical state by accident is mind-bogglingly small and, to all intents and purposes, impossible.,, of the order of 10^-50 of possible small biomolecules and even less for proteins,”,,, “what exactly is the advantage that criticality confers?” https://medium.com/the-physics-arxiv-blog/the-origin-of-life-and-the-hidden-role-of-quantum-criticality-ca4707924552
Moreover, the following article points out that the unresolved enigma of protein folding, that is to say, the unresolved enigma for how a protein might achieve its basic 3-dimensional form, can be easily explained if the process of folding is a quantum affair.
Physicists Discover Quantum Law of Protein Folding – February 22, 2011 Quantum mechanics finally explains why protein folding depends on temperature in such a strange way. Excerpt: First, a little background on protein folding. Proteins are long chains of amino acids that become biologically active only when they fold into specific, highly complex shapes. The puzzle is how proteins do this so quickly when they have so many possible configurations to choose from. To put this in perspective, a relatively small protein of only 100 amino acids can take some 10^100 different configurations. If it tried these shapes at the rate of 100 billion a second, it would take longer than the age of the universe to find the correct one. Just how these molecules do the job in nanoseconds, nobody knows.,,, Today, Luo and Lo say these curves can be easily explained if the process of folding is a quantum affair. By conventional thinking, a chain of amino acids can only change from one shape to another by mechanically passing through various shapes in between. But Luo and Lo say that if this process were a quantum one, the shape could change by quantum transition, meaning that the protein could ‘jump’ from one shape to another without necessarily forming the shapes in between.,,, Their astonishing result is that this quantum transition model fits the folding curves of 15 different proteins and even explains the difference in folding and unfolding rates of the same proteins. That's a significant breakthrough. Luo and Lo's equations amount to the first universal laws of protein folding. That’s the equivalent in biology to something like the thermodynamic laws in physics. http://www.technologyreview.com/view/423087/physicists-discover-quantum-law-of-protein/
Thus in conclusion, the ‘bottom up’ reductive materialistic framework of Darwinian evolution is found to be grossly inadequate for explaining how any particular organism might achieve its basic form. Moreover, to state what should be glaringly obvious, since neo-Darwinian explanations are grossly inadequate for explaining how any particular organism might achieve its basic form, then neo-Darwinian speculations for how one type of organism might transform into another type of organism are based on pure fantasy and have no discernible experimental basis in reality. Whereas, on the other hand, Theism, especially with these recent breakthroughs in quantum biology that strongly indicate that information is somehow coming into the developing embryo from outside space-time,,,
Darwinian Materialism vs Quantum Biology - video https://www.youtube.com/watch?v=LHdD2Am1g5Y
,,,Theism on the other hand is found to be very well supported in its claim that God has formed each of us in our mother’s womb.
Verses: Psalm 139:13-14 For You formed my inward parts; You covered me in my mother’s womb. I will praise You, for I am fearfully and wonderfully made; Marvelous are Your works, And that my soul knows very well. Jeremiah 1:5 “Before I formed you in the womb I knew you, before you were born I set you apart; I appointed you as a prophet to the nations.” Psalm 139:13 For you created my inmost being; you knit me together in my mother's womb.

And here is a excellent powerpoint presentation by Dr. Jonathan Wells, starting around the 15:00 minute mark, showing that the central dogma of Darwinian evolution, which simply stated is “DNA makes RNA makes protein makes us”, is incorrect at every step.
Design Beyond DNA: A Conversation with Dr. Jonathan Wells – video (14:36 minute mark) – January 2017 https://youtu.be/ASAaANVBoiE?t=876 Dr. Jonathan Wells: Biology’s Quiet Revolution - podcast - April 15, 2016 On this episode of ID the Future, Dr. Jonathan Wells discusses a popular claim, which he describes as “DNA makes RNA makes protein makes us”—or, every organism contains a program for itself in its DNA. Though this view fits neatly with the perspective of Darwinian evolution, it has been shown to be incorrect at every step. Listen in as Dr. Wells explains. https://www.discovery.org/multimedia/audio/idtf/2016/04/dr-jonathan-wells-biologys-quiet-revolution/
Shoot, DNA does not even control its own shape much less does it control the shape of the organism that it resides in. As the following study found, “Our results demonstrate that the spatial organization of genomes is tissue-specific and point to a role for tissue-specific spatial genome organization in the formation of recurrent chromosome arrangements among tissues.”
Tissue-specific spatial organization of genomes - June 21, 2004 Results Using two-dimensional and three-dimensional fluorescence in situ hybridization we have carried out a systematic analysis of the spatial positioning of a subset of mouse chromosomes in several tissues. We show that chromosomes exhibit tissue-specific organization. Chromosomes are distributed tissue-specifically with respect to their position relative to the center of the nucleus and also relative to each other. Subsets of chromosomes form distinct types of spatial clusters in different tissues and the relative distance between chromosome pairs varies among tissues. Consistent with the notion that nonrandom spatial proximity is functionally relevant in determining the outcome of chromosome translocation events, we find a correlation between tissue-specific spatial proximity and tissue-specific translocation prevalence. Conclusions Our results demonstrate that the spatial organization of genomes is tissue-specific and point to a role for tissue-specific spatial genome organization in the formation of recurrent chromosome arrangements among tissues. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC463291/
To further drive the point home that the sequences in DNA cannot explain how any particular kind of organism achieves its basic form, in the following article Dr. Jonathan Wells states, “I now know as an embryologist,,,Tissues and cells, as they differentiate, modify their DNA to suit their needs. It's the organism controlling the DNA, not the DNA controlling the organism.”
Ask an Embryologist: Genomic Mosaicism - Jonathan Wells - February 23, 2015 Excerpt: humans have a "few thousand" different cell types. Here is my simple question: Does the DNA sequence in one cell type differ from the sequence in another cell type in the same person?,,, The simple answer is: We now know that there is considerable variation in DNA sequences among tissues, and even among cells in the same tissue. It's called genomic mosaicism. In the early days of developmental genetics, some people thought that parts of the embryo became different from each other because they acquired different pieces of the DNA from the fertilized egg. That theory was abandoned,,, ,,,(then) "genomic equivalence" -- the idea that all the cells of an organism (with a few exceptions, such as cells of the immune system) contain the same DNA -- became the accepted view. I taught genomic equivalence for many years. A few years ago, however, everything changed. With the development of more sophisticated techniques and the sampling of more tissues and cells, it became clear that genetic mosaicism is common. I now know as an embryologist,,,Tissues and cells, as they differentiate, modify their DNA to suit their needs. It's the organism controlling the DNA, not the DNA controlling the organism. http://www.evolutionnews.org/2015/02/ask_an_embryolo093851.html
Moreover, this, what can be termed, positional information, which is not reducible to DNA sequences and which specifies the three-dimensional arrangement of the molecular components of the cell and of the organism, is found to be enormous. Much greater than the sequential information, as great as that sequential information is, that is encoded on DNA. As Dr. Doug Axe states in the following video at the 1 hour 16 minute mark,
"There is also a presumption, typically when we talk about our genome, (that the genome) is a blueprint for making us. And that is actually not a proven fact in biology. That is an assumption. And (one) that I question because I don't think that 4 billion bases, which would be 8 billion bits of information, that you would actually have enough information to specify a human being. If you consider for example that there are a quadrillion neural connections in the human brain, that's vastly more neural connections in the human brain than there are bits (of information) in the human genome. So,,, there's got to be something else going on that makes us what we are." Doug Axe - Intelligent Design 3.0 - Stephen C. Meyer - video https://youtu.be/lgs6J4LqeqI?t=4575
In fact, the information content that is found to be in a one cell bacterium, when working from the thermodynamic perspective, is found to be 10 to the 12 bits,,,
Biophysics – Information theory. Relation between information and entropy: - Setlow-Pollard, Ed. Addison Wesley Excerpt: Linschitz gave the figure 9.3 x 10^12 cal/deg or 9.3 x 10^12 x 4.2 joules/deg for the entropy of a bacterial cell. Using the relation H = S/(k In 2), we find that the information content is 4 x 10^12 bits. Morowitz' deduction from the work of Bayne-Jones and Rhees gives the lower value of 5.6 x 10^11 bits, which is still in the neighborhood of 10^12 bits. Thus two quite different approaches give rather concordant figures. http://www.astroscu.unam.mx/~angel/tsb/molecular.htm
Which is equivalent of 100 million pages of Encyclopedia Britannica. 'In comparison,,, the largest libraries in the world,, have about 10 million volumes or 10^12 bits.”
“a one-celled bacterium, e. coli, is estimated to contain the equivalent of 100 million pages of Encyclopedia Britannica. Expressed in information in science jargon, this would be the same as 10^12 bits of information. In comparison, the total writings from classical Greek Civilization is only 10^9 bits, and the largest libraries in the world – The British Museum, Oxford Bodleian Library, New York Public Library, Harvard Widenier Library, and the Moscow Lenin Library – have about 10 million volumes or 10^12 bits.” – R. C. Wysong 'The information content of a simple cell has been estimated as around 10^12 bits, comparable to about a hundred million pages of the Encyclopedia Britannica." Carl Sagan, "Life" in Encyclopedia Britannica: Macropaedia (1974 ed.), pp. 893-894
In the following video, it is noted that the information to build a human infant, atom by atom, would take up the equivalent of enough thumb drives to fill the Titanic, multiplied by 2,000.
In a TED Talk, (the Question You May Not Ask,,, Where did the information come from?) - November 29, 2017 Excerpt: Sabatini is charming.,,, he deploys some memorable images. He points out that the information to build a human infant, atom by atom, would take up the equivalent of enough thumb drives to fill the Titanic, multiplied by 2,000. Later he wheels out the entire genome, in printed form, of a human being,,,,: [F]or the first time in history, this is the genome of a specific human, printed page-by-page, letter-by-letter: 262,000 pages of information, 450 kilograms.,,, https://evolutionnews.org/2017/11/in-a-ted-talk-heres-the-question-you-may-not-ask/
The following video states that "There are 10^28 atoms in the human body.,, The amount of data contained in the whole human,, is 3.02 x 10^32 gigabytes of information. Using a high bandwidth transfer, that data would take about 4.5 x 10^18 years to teleport 1 time. That is 350,000 times the age of the universe."

As to:
How Do Cells In A Body Know Where They Are Supposed To Be?
And as they admit,,
As cells divide to form tissues and organs in multicell organisms, they move to where they belong, informed by a series of cues that scientists have yet to observe or fully understand.... ,,, Exactly how these local in-plane shear forces are spread throughout a tissue — important in collective tissue behavior — is not understood, ,,,
Not only do they not know, nobody knows, "How Do Cells In A Body Know Where They Are Supposed To Be?" In the following video at the 1:00 minute mark, molecular-biologist Doug Axe states, "We have no idea how a single cell produces an adult."
"The mere fact that a firefly comes from a single cell that then develops into a firefly puts it in a completely different league [from an iPhone]. That doesn’t happen with smartphones. Factories make smartphones. Fireflies come from fireflies and come from an initial fertilized cell. It’s absolutely mind-boggling. We have no idea how a single cell produces an adult. These things are marvelous." - Doug Axe - The Problem with Theistic Evolution - video - 1:00 minute mark https://www.youtube.com/watch?v=ndRBUyW6EbM
And in the following video at the 7:25 minute mark, Alexander Tsiaras states, "The magic of the mechanisms inside each genetic structure saying exactly where that nerve cell should go, the complexity of these, the mathematical models on how these things are indeed done, are beyond human comprehension.."
"It's a Mystery, It's Magic, It's Divinity" - Casey Luskin - March 22, 2012 Excerpt: "The magic of the mechanisms inside each genetic structure saying exactly where that nerve cell should go, the complexity of these, the mathematical models on how these things are indeed done, are beyond human comprehension. Even though I am a mathematician, I look at this with the marvel of how do these instruction sets not make these mistakes as they build what is us. It's a mystery, it's magic, it's divinity." Alexander Tsiaras: Conception to birth — visualized – video – 7:25 minute mark https://youtu.be/fKyljukBE70?t=443
It is safe to say nobody really knows how an organism achieves its basic form. In the following article, Michael Denton remarks that, 'to date the form of no individual cell has been shown to be specified in detail in a genomic blueprint.'
The Types: A Persistent Structuralist Challenge to Darwinian Pan-Selectionism - Michael J. Denton - 2013 Excerpt: Cell form ,,,Karsenti comments that despite the attraction of the (genetic) blueprint model there are no “simple linear chains of causal events that link genes to phenotypes” [77: p. 255]. And wherever there is no simple linear causal chain linking genes with phenotypes,,,—at any level in the organic hierarchy, from cells to body plans—the resulting form is bound to be to a degree epigenetic and emergent, and cannot be inferred from even the most exhaustive analysis of the genes.,,, To this author’s knowledge, to date the form of no individual cell has been shown to be specified in detail in a genomic blueprint. As mentioned above, between genes and mature cell form there is a complex hierarchy of self-organization and emergent phenomena, rendering cell form profoundly epigenetic. http://bio-complexity.org/ojs/index.php/main/article/view/BIO-C.2013.3/BIO-C.2013.3
And in the following article entitled 'how do rod-like bacteria control their geometry?', in the concluding paragraph, the authors conceded that, 'We are still far from unravelling the fundamental “engineering” challenges that biology has to overcome in shaping single cells as well as multi-cellular tissues.,,,'
Getting into shape: how do rod-like bacteria control their geometry? - March 31, 2014 Excerpt from concluding paragraph: We are still far from unravelling the fundamental “engineering” challenges that biology has to overcome in shaping single cells as well as multi-cellular tissues.,,, https://arxiv.org/pdf/1404.0015.pdf
In short, molecular biologists don't even understand how a single cell might achieve its basic form, much less do they understand how a multicellular organism might achieve its basic form. This failure of Darwinian evolution, particularly the failure of the reductive materialism on which Darwinian evolution is based, to be able to explain the basic form of any particular organism occurs at a very low level. Much lower than DNA itself. In the following article entitled 'Quantum physics problem proved unsolvable: Gödel and Turing enter quantum physics', which studied the derivation of macroscopic properties from a complete microscopic description, the researchers remark that even a perfect and complete description of the microscopic properties of a material is not enough to predict its macroscopic behaviour.,,, The researchers further commented that their findings challenge the reductionists' point of view, as the insurmountable difficulty lies precisely in the derivation of macroscopic properties from a microscopic description."
Quantum physics problem proved unsolvable: Gödel and Turing enter quantum physics - December 9, 2015 Excerpt: A mathematical problem underlying fundamental questions in particle and quantum physics is provably unsolvable,,, It is the first major problem in physics for which such a fundamental limitation could be proven. The findings are important because they show that even a perfect and complete description of the microscopic properties of a material is not enough to predict its macroscopic behaviour.,,, "We knew about the possibility of problems that are undecidable in principle since the works of Turing and Gödel in the 1930s," added Co-author Professor Michael Wolf from Technical University of Munich. "So far, however, this only concerned the very abstract corners of theoretical computer science and mathematical logic. No one had seriously contemplated this as a possibility right in the heart of theoretical physics before. But our results change this picture. From a more philosophical perspective, they also challenge the reductionists' point of view, as the insurmountable difficulty lies precisely in the derivation of macroscopic properties from a microscopic description." http://phys.org/news/2015-12-quantum-physics-problem-unsolvable-godel.html
Despite the fact that nobody has a clue how one cell might become a multicellular creature, and despite the fact that we have clear evidence that we will never derive "macroscopic properties from a (complete) microscopic description", none-the-less Darwinists still confidently teach that it is possible to transform one creature into another creature by mutations to DNA alone.

Yet, as Jonathan Wells states in the following article, Studies using saturation mutagenesis in the embryos of fruit flies, roundworms, zebrafish and mice also provide evidence against the idea that DNA specifies the basic form of an organism. Biologists can mutate (and indeed have mutated) a fruit fly embryo in every possible way, and they have invariably observed only three possible outcomes: a normal fruit fly, a defective fruit fly, or a dead fruit fly.
Jonathan Wells: Far from being all-powerful, DNA does not wholly determine biological form - March 31, 2014 Excerpt: Studies using saturation mutagenesis in the embryos of fruit flies, roundworms, zebrafish and mice also provide evidence against the idea that DNA specifies the basic form of an organism. Biologists can mutate (and indeed have mutated) a fruit fly embryo in every possible way, and they have invariably observed only three possible outcomes: a normal fruit fly, a defective fruit fly, or a dead fruit fly. https://uncommondescent.com/intelligent-design/jonathan-wells-far-from-being-all-powerful-dna-does-not-wholly-determine-biological-form/ Response to John Wise - October 2010 Excerpt: But there are solid empirical grounds for arguing that changes in DNA alone cannot produce new organs or body plans. 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–,,, (As Jonathan Wells states),,, We can modify the DNA of a fruit fly embryo in any way we want, and there are only three possible outcomes: A normal fruit fly; A defective fruit fly; or A dead fruit fly. http://www.evolutionnews.org/2010/10/response_to_john_wise038811.html
In the following video, at the 5:55 minute mark, Stephen Meyer states that '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.'
‘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-plan. 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 - Functional Proteins and Information for Body Plans – video – 5:55 minute mark https://youtu.be/hs4y4XLGQ-Y?t=354
