Return to David's theory of evolution PART 2 (Evolution)

DAVID: The gaps as missing fossils is a theory not supported by the Camrian research now that soft tissue fossils are turning up and Cambrian fossils are being found all over the world as the gap remains.
DAVID: Please, stop changing facts. Brains and nerves have been seen only in the Cambrian, not the Edicaran!!! As for all the 'new' fossils, all they have done is emphasize the gap.

dhw: Please stop trying to minimize the importance of the neuropeptide article. No one says brains and nerves already existed before the Cambrian, but: “The modern brain arose from hundreds of millions of years of incremental advances in complexity. Evolutionary biologists have traced that progress back through the branch of the animal family tree that includes all creatures with central nervous systems, the bilaterians, but it is clear that fundamental elements of the nervous system existed much earlier.”

I am not minimizing the neuropeptides. Of course they fit my theory that the basis of the continuity of evolution is in early and complete development of necessary new bochemicals which precede new processes by new organs.

dhw: […] Darwin would have been delighted at this vindication of his theory. If rudimentary brains and nervous systems and sexual reproduction already existed long before the Cambrian, what you call the “jumps” are nothing like as jumpy as you have made them out to be, even to the point of your claiming that the Cambrian produced species without any precursors (the exact opposite of continuity). [I am happy to change “rudimentary brains etc, to “fundamental elements”, as it makes no difference to the argument.]

DAVID: Your Darwin brain has assumed facts about the Ediacaran that have no proof. My only previous comment was about Edicaran animals possibly having some form of sex noted they were sessile and would have to float sperm over in the ocean to find eggs. Your rudimentary brains and nerves are figments of your wishful imagination as Darwin theory disappears.

dhw: If fundamental elements of brains and nerves appeared before actual brains and nerves (it was you who pointed out that sex may have been another example of early precursors), this can only be seen as vindication of the theory that these organs were the products of a continuous process rather than sudden jumps. You yourself support the concept of continuity when it confirms a direct line of descent from bacteria to humans, but you support the concept of sudden jumps when it suits your theory that only God could produce species without precursors.

Yes, a continuous of necessary biochemicals prior to new organs or phenotypes.

Human membrane pore

DAVID: From your amorphous wandering answer, I still don't know whether you undersand irreducable complexity and its full import as a concept, or you don't wish to accept it.

dhw: I accept the concept of irreducible complexity in relation to the cell as a living, sentient, reproducing, flexible and intelligent entity – and that includes its ability to respond to different conditions by changing its forms. I don’t know why you think my comment constitutes an amorphous wandering answer. What is your objection to it?

DAVID: The concept says all parts must be formed simultaneously. Not your ambiguous amorphous comment.

dhw: All parts of what?

Of the fully ooperating pore in this case

Ediacaran-Cambrian transition: 410,000 years

DAVID: I'm sick of this twisting of the gap importance by dhw finding old comments about it.

dhw: Next you’ll be telling us all palaeontologists believe that during the Cambrian, God created new, fully developed species that had no precursors. Yet again: the shortening of the gap between Ediacaran and Cambrian is irrelevant to the arguments that explain the gaps in the fossil record, which remain just as valid in 2022 as in 2019.

DAVID: The Cambrian gap it seems is shorter than all other gaps known!!! Accept it!!

dhw: OK, I accept it. Now will you please accept that the arguments explaining gaps in the fossil record are just as valid now as they were in 2019.

We do not know how speciation occurs in the time period which is required. No interval is known. The gaps are gaps because they are gaps. The Edicaran/Cambrian gap is amazingly short compared to all others, consdiering the enormnous jump in complexity.

Entropy

DAVID: Note my bold for an important view of the importance of ecosystems. Ecosystems ae balanced to maindtain lkife in general. Note dhw disparages them as food. One role is tooffer food for all.

dhw: You never cease to misrepresent my view of ecosystems. Every ecosystem serves to maintain life, and provides food for all the organisms within it. But that does not mean that every ecosystem and every organism in the whole history of life on Earth was specially designed as an “absolute requirement” in preparation for us humans and our food. Please stop this silly attempt to distract attention from the illogicality of your anthropocentric theory of evolution.

dhw: As you have not replied, I trust we have heard the last of this particular dodge.

I'm just avoiding another discussion of the same old thing. My view about now I view God are widely expressed here.
