Return to David's theory of evolution PART 1 (Evolution)

DAVID: What you refuse to accept is I fully believe God does it any way He wishes and I don't need to queston it or satisfy your confusion about how God did it (His reasoning) as I view God.

If God exists, I fully accept that he would run evolution “any way he wishes”, and I have offered various alternative versions of his wishes and his methods of fulfilling his wishes. As you view God, he had one wish, and fulfilled it by deliberately not fulfilling it until he had created all sorts of things that had no connection with his one wish. And you have no idea why.

As above, His reasoning as to method doesn't matter to me. His created history tells me what He did.

Ediacaran-Cambrian transition: 410,000 years

dhw: I’m not disputing the findings, but I’ve got used to the fact that “recognized experts in the field” often disagree with one another, and since this is a brand new article, I thought there might be other views. In the abstract, it says:

"The replacement of the late Precambrian Ediacaran biota by morphologically disparate animals at the beginning of the Phanerozoic was a key event in the history of life on Earth, the mechanisms and the time-scales of which are not entirely understood[/b].”

What you have quoted is a standard form of beginning an article: there is a problem we are trying to solve and then results are presented of findings.

dhw: The gap between Ediacaran and Cambrian is irrelevant to our discussion of the “gaps” in the fossil record.

DAVID: It is very relevant. Such a huge change in animal forms in such a short period doesn't fit the usual timing of a speciation change as in the whale series.

dhw: First of all, how fully developed are the new forms?

They lived as Cambrians. How much development was needed?

dhw: And secondly, even 410,000 years is a long time in terms of generations, and it is generations that create new species, not time. You yourself wrote:

DAVID: The true answer to how long speciation takes is unknown. The many gaps don't tell us.

dhw: Once again, the argument revolves round missing fossils, not around time:

The information I presented yesterday is exactly about fossils in two periods demonstrating the short time for massive change. Most gaps are much much longer as you know.

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.

dhw: So it is far from true to claim that there are no more fossils to be found – they are turning up all the time. And discoveries that indicate rudimentary brains and nervous systems and possibly sex existing long before the Cambrian would seem to indicate continuity rather than de novo speciation.

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.

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.

dhw: 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. [You wrote: How does a sex organ discovery support your wild theory that dispenses with the Cambrian gap?]

DAVID: 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!

dhw: It certainly has, and 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).

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.
