Now, here comes the good part that I dont tell people until they engage me with my question..
I WAS able to get my Question (Asking for a plausible chronological evolutionary order for Mans 10 VITAL organs "answered" by Prof. Dr. Andreas Schmidt-Rhaesa, He is the guy who LITERALLY wrote the book "evolution of organ systems"
I just showed you that integument and nervous systems were the first two to evolved. And then you gave up.
https://www.amazon.com/Evolution-Organ-Systems-Andreas-Schmidt-Rhaesa/dp/0198566697
He is a professor / scientist / and a world renown expert on the "Evolution of Organs" He wrote the book! Do you think that HE is "qualified" to answer my question?.. LOL
He says:
Nature volume 452, pages745–749(2008)
Broad phylogenomic sampling improves resolution of the animal tree of life
...Analysed in combination with existing sequences, our data reinforce several previously identified clades that split deeply in the animal tree (including Protostomia, Ecdysozoa and Lophotrochozoa), unambiguously resolve multiple long-standing issues for which there was strong conflicting support in earlier studies with less data (such as velvet worms rather than tardigrades as the sister group of arthropods5), and provide molecular support for the monophyly of molluscs, a group long recognized by morphologists. In addition, we find strong support for several new hypotheses. These include a clade that unites annelids (including sipunculans and echiurans) with nemerteans, phoronids and brachiopods, molluscs as sister to that assemblage, and the placement of ctenophores as the earliest diverging extant multicellular animals. A single origin of spiral cleavage (with subsequent losses) is inferred from well-supported nodes. Many relationships between a stable subset of taxa find strong support, and a diminishing number of lineages remain recalcitrant to placement on the tree.
And he seems to agree with my point that integument and nervous system evolved first:
The Evolution of Organ Systems
Now, keep in mind.. He did give an "answer"
Not one, but several. But as you see, his answer and mine agree (although he has a qualification about muscles and nervous systems).
If you had actually read his book you'd have realized that. You see what happens when you don't read the original article?
but if you have a deep emotional attachment to "evolution" due to philosophical reasons you DONT want to know his answer (Hint : Not good for TOE) Your choice..
In fact, Dr. Schmidt-Rhaesa repeatedly confirms the fact of evolution, not just in the book someone told you about, but in numerous other papers and books.
and... here, Dr. Schmidt-Rhaesa is cited for his finding that musculature of bilaterans (like us) did not originate with cnidarians, as I told you:
Front. Cell Dev. Biol., 23 January 2017
Independent evolution of striated muscles in cnidarians and bilaterians
Striated muscles are present in bilaterian animals (for example, vertebrates, insects and annelids) and some non-bilaterian eumetazoans (that is, cnidarians and ctenophores). The considerable ultrastructural similarity of striated muscles between these animal groups is thought to reflect a common evolutionary origin1,2. Here we show that a muscle protein core set, including a type II myosin heavy chain (MyHC) motor protein characteristic of striated muscles in vertebrates, was already present in unicellular organisms before the origin of multicellular animals. Furthermore, ‘striated muscle’ and ‘non-muscle’ myhc orthologues are expressed differentially in two sponges, compatible with a functional diversification before the origin of true muscles and the subsequent use of striated muscle MyHC in fast-contracting smooth and striated muscle. Cnidarians and ctenophores possess striated muscle myhc orthologues but lack crucial components of bilaterian striated muscles, such as genes that code for titin and the troponin complex, suggesting the convergent evolution of striated muscles. Consistently, jellyfish orthologues of a shared set of bilaterian Z-disc proteins are not associated with striated muscles, but are instead expressed elsewhere or ubiquitously. The independent evolution of eumetazoan striated muscles through the addition of new proteins to a pre-existing, ancestral contractile apparatus may serve as a model for the evolution of complex animal cell types.
From The Evolution of Organ Systems link you found:
"Systematics has developed rapidly during the past two decades. A multitude of new methods and contributions from a diversity of biological fields including molecular genetics and developmental biology have provided a wealth of phylogenetic hypotheses, some confirming traditional views others contradicting them. Despite such inconsistencies, it is now possible to recognize robust regions of a 'tree of life' and also to identify problematic areas which have yet to be resolved. This is the first book to apply the current state of phylogeny to an evolutionary interpretation of animal organ systems and body architecture, providing alternative theories in those cases of continuing controversy.
Organs do not appear suddenly during evolution; instead they are composed of far simpler structures. In some cases it is even possible to trace particular molecules or physiological pathways as far back as pre-animal history. What emerges is a fascinating picture, showing how animals have combined ancestral and new elements in novel ways to form constantly changing responses to environmental requirements." (my emphasis)
And again, this is what I told you.
And this is where most YE creationist end this conversation, because they really don't want to hear anything that might cause them to doubt their new doctrine of YE creationism because, It has nothing to do with Science and everything to do with their modern revision of scripture.
