Developing embryo’s “rosette” new to science

This is good point to confront evolution. Darwin said it was one of his top three reasons for why evolution was true. All fetus look the same equals common deescent. Yet its all just a line of reasoning and not evidence at all. Another line of reasoning deflats it. As follows. A common designer has made all biology off the same rack SO it could only be that at a early stage all would look the same. Hows that?Robert Byers

Also of note: The mouse is not enough - February 2011 Excerpt: Richard Behringer, who studies mammalian embryogenesis at the MD Anderson Cancer Center in Texas said, “There is no ‘correct’ system. Each species is unique and uses its own tailored mechanisms to achieve development. By only studying one species (eg, the mouse), naive scientists believe that it represents all mammals.” http://www.the-scientist.com/news/display/57986/ Haeckel's Bogus Embryo Drawings - video http://www.youtube.com/watch?v=ecH5SKxL9wk Gene Regulation Differences Between Humans, Chimpanzees Very Complex – Oct. 17, 2013 Excerpt: Although humans and chimpanzees share,, similar genomes (70% per Tomkins), previous studies have shown that the species evolved major differences in mRNA expression levels.,,, http://www.sciencedaily.com/releases/2013/10/131017144632.htm Evolution by Splicing – Comparing gene transcripts from different species reveals surprising splicing diversity. – Ruth Williams – December 20, 2012 Excerpt: A major question in vertebrate evolutionary biology is “how do physical and behavioral differences arise if we have a very similar set of genes to that of the mouse, chicken, or frog?”,,, A commonly discussed mechanism was variable levels of gene expression, but both Blencowe and Chris Burge,,, found that gene expression is relatively conserved among species. On the other hand, the papers show that most alternative splicing events differ widely between even closely related species. “The alternative splicing patterns are very different even between humans and chimpanzees,” said Blencowe.,,, http://www.the-scientist.com/?articles.view%2FarticleNo%2F33782%2Ftitle%2FEvolution-by-Splicing%2F A Listener's Guide to the Meyer-Marshall Debate: Focus on the Origin of Information Question -Casey Luskin - December 4, 2013 Excerpt: "There is always an observable consequence if a dGRN (developmental gene regulatory network) subcircuit is interrupted. Since these consequences are always catastrophically bad, flexibility is minimal, and since the subcircuits are all interconnected, the whole network partakes of the quality that there is only one way for things to work. And indeed the embryos of each species develop in only one way." - Eric Davidson http://www.evolutionnews.org/2013/12/a_listeners_gui079811.html Darwin or Design? - Paul Nelson at Saddleback Church - Nov. 2012 - ontogenetic depth (excellent update) - video Text from one of the Saddleback slides: 1. Animal body plans are built in each generation by a stepwise process, from the fertilized egg to the many cells of the adult. The earliest stages in this process determine what follows. 2. Thus, to change -- that is, to evolve -- any body plan, mutations expressed early in development must occur, be viable, and be stably transmitted to offspring. 3. But such early-acting mutations of global effect are those least likely to be tolerated by the embryo. Losses of structures are the only exception to this otherwise universal generalization about animal development and evolution. Many species will tolerate phenotypic losses if their local (environmental) circumstances are favorable. Hence island or cave fauna often lose (for instance) wings or eyes. http://www.saddleback.com/mc/m/7ece8/bornagain77

This 'rosette' reminds me of this: Alexander Tsiaras: Conception to birth — visualized – video http://www.youtube.com/watch?v=fKyljukBE70 Comment on/from 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 BIOLOGISTS LOST SIGHT OF THE MEANING OF LIFE — AND ARE NOW STARING IT IN THE FACE - Stephen L. Talbott - May 2012 Excerpt: 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 — 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.,,, 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 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. http://ai.stanford.edu/~serafim/CS374_2006/papers/Mattick_NRG2004.pdf One Body - animation - video http://www.youtube.com/watch?v=pDMLq6eqEM4bornagain77
