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

Punctuated trilobites

DAVID: The grasper organ found in trilobites is Cambrian, and presumes a penis. The bold is your pure invention. I did mention Edicarans are thought to be simple animals, so they possibly had sexual reproduction, but as sessile forms, sperm would have to float over to find an egg somehow. In Cambrian reproduction intromission is assumed. Your theoretical struggles show their rigidity.

You are right, my bold goes too far, as you said that Ediacaran animals “could have had” sex, not “did have”. However, the article on neuropeptides showed us that precursors to the fully developed Cambrian forms (brains and nervous systems) existed earlier, thus confirming the concept of continuity. And if the same “could have” applied to sexual reproduction, the theory of continuity can hardly be dismissed as wild.

As you have just proven my theory, thank you! The true continuity of evolution is the ever- developing complexity of living biochemistry, as I have stated. Jumps in forms (gaps) are made possible by new biochemical proteins, as the neuropeptides example. Your education has advanced far beyond Darwin!

DAVID: You may accept design theory, but totally ignore the import of irreducible complexity. All newly appearing cell forms most come complete with all functions intact and operating. Without that arangement, it won't work.

dhw: I presume you are now talking about adaptation and innovation, in which cells take on new forms, and of course they must work. When conditions change, many life forms die. Survival depends on the flexibility of cells to change their structure.

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.

DAVID: All cells work on intelligent information. New species use cells just like the ones in the old species, but teh cells are now arranged to operate cooperatively in new body parts and body forms.

dhw: I don’t know why you want to muddy the waters with “intelligent information”. It is the intelligence of cells that interprets and uses information, which is passive. And you’ve hit the nail on the head: the cells cooperate to create new forms.

You have always been uncomfortable with the issue of information in living tissue.

DAVID: How do cells take new body part forms? By design from the designer who undertand and plans for the future form and its new functions and uses. The thought that simple living cells can forsee the future and design for it to create the known gaps in the fossil record ( as the Cambrian) is preposterous.

dhw: I don’t know how many times I have to repeat that in my theory cells do not foresee the future! They respond to conditions in their present: either they die, or they adapt (both proven) or they exploit the new conditions by designing new ways of using them (innovation, but not proven).

I fully know your strained theory about cell's abilities. For new forms able to handle new needs in their future, theories about the future must exist to create new design

dhw: The gaps in the fossil record are a different subject, which we have now discussed ad nauseam, with you refusing to consider the various explanations that have been offered.

The gaps are directly related to the issue of cells roles in speciation

dhw: But of course you have every right to cling to your theory that 3.8 billion years ago your God produced an instruction manual for every single innovation, or alternatively he kept popping in to engineer each and every one, because each and every one was an “absolute requirement” for his design of us humans.

Thank you
