Limits to Evolution and an Out of Place Fossil – Quick DpSU 14 June

Our first DpSU is entitled “The Cost of Adaptations Limits Evolution“. This seems to be a classic Micro/Macro Evolution story, and by my reckoning a Type AE DpSU (Misrepresented Study).

Or in this case, studies. Mr Thomas is talking about two studies from a recent issue of the journal Science in which bacteria (Methylobacterium and E. coli) were experimented upon, with the researches investigating the effects of multiple mutations on Epistasis. Epistasis, btw, is (to quote WP) “the phenomenon where the effects of one gene are modified by one or several other genes, which are sometimes called modifier genes.” Interestingly, the ICR article does not mention the word Epistasis anywhere outside of it’s references.

The problem I have with this article is that I don’t have access to any part of the studies beyond the abstract, so I’m a bit limited about what I can say.

To distil the ICR article down somewhat, what the studies seem to show is that, as beneficial mutations accumulate, their benefits decrease, causing a diminishing returns situation. And this disproves evolution how? Mr Thomas extrapolates this to say that animals only have a limited ability to evolve. So Baraminology is out the door then? Definiately an AE, though I don’t have the time to deconstruct the article.

As for the second, “Out of Place Marine Fossil Disrupts Evolutionary Index“.

The science behind this is that a group of animals from the Cambrian period, the Anomalocaridids, have been shown to have survived significantly longer. It might be added that we already knew that to a certain degree, but that wont stop Mr Thomas.

No, a new discovery shows (according to him) that the whole ‘Evolutionary Index’ is unreliable, as Anomalocaridids are a defining feature of Cambrian rocks, indeed make Cambrian rocks Cambrian. There is, however, no reference to that claim, which would help. He also claims that Noah’s flood predicts that fossils should be disorganised, and that this is a prime example of that. I’ll cover this kind of thing in my Noah’s Ark series shortly, but I’ll add here that the Flood would disorganise fossils a whole lot more than is observed.

Thomas also throws in a declaration that the fossils found are already perfect, and therefore could not evolve further and could not have been evolved either — therefore God (spot the logical fallacy anyone?). Also, he says that “no anomalocaridid looks like an evolutionary transition”. *sigh*. What is an evolutionary transition by Mr Thomas’ unknown definition anyway. A ‘transition’ looks no different from any other fossil, and is defined only by the prior discovery of fossils that have the potential to be ancestors/aunts and descendants/nieces of the new discovery. If you find fossils in a different order, different fossils are classified as ‘transitional’.

And that’s all I have time for tonight…
