Ediacaran-Cambrian transition: 410,000 years

DAVID: Why do you throw old material in the face of new findings? Because it upsets your rigid theories you cling to. I'm trying to educate you.

dhw: I asked: "Who has accepted it as valid? I thought this theory was hot off the press. Do you really believe that all research into the subject is now over? In any case, this one discovery does not invalidate any of the points made in the articles I posted." You have not answered. The shortened gap between Ediacaran and Cambrian does not make the slightest difference to the discussion on why we don’t have fossils of every single transition from species to species. Its only possible relevance is to the time available for speciation, and your next answer appears to confirm that it is NOT relevant.

Of course research continues. You are carefully throwing up lots of speciation theories to avoid the point that the complex animals of Cambrian appearing in a short time demands a designing mind produced them.


DAVID: You are straw clutching. Shapiro's theory is fine with this.

dhw: Why is it straw clutching to point out that changes take place through generations rather than through the passing of time, and why do you regard the theory of cellular intelligence as straw clutching – especially if we propose that your God may have designed it?

DAVID: Genertions pass though time. Both are involved.

dhw: But changes to the genome take place by generations, not by the passage of time. Please tell us why this counts as “straw clutching”.

True speciation is a major genome change. Most new species appear suddenly as if newly designed.


Punctuated trilobites

DAVID: our favorite Cambrians are yielding more secrets. It has always been presumed sex appeared in the Cambrian, but Edicraran 'frond-like animals could have had sex earlier.

dhw: Many thanks for this. As with the article on “neuropeptides”, we are slowly learning that fundamental features of “modern” species (brains, nervous systems, and now sex) did not suddenly appear in the Cambrian after all. New fossils keep emerging and confirming the theory that the evolution of species is a continuous process of common descent as life forms vary, adapt and innovate.

How does a sex organ discovery support your wild theory that dispenses with the Cambrian gap?
