From the Thumb,
The title gets the principal objection of any creationist out of the way: yes, this population of Podarcis sicula is still made up of lizards, but they're a different kind of lizard now. Evolution works. (emphasis in original)
So, the thinking must go, if we see the evolution of one kind of lizard into a different kind of lizard (in only 30 years), then imagine what can occur over the course of millions of years? Unwarranted extrapolation at work, once again.
The reference, from the Thumb, is to a National Geographic article titled, Lizards Rapidly Evolve After Introduction to Island. From the article,
Italian wall lizards introduced to a tiny island off the coast of Croatia are evolving in ways that would normally take millions of years to play out, new research shows.
Yet, if the changes seen normally take millions of years to occur, shouldn't one be skeptical of either the evolution documented or the claim that it normally takes millions of years? And, if the changes were the same as one would expect over millions of years, aren't we now in a position to perform experiments in much the same manner as animal breeders? Indeed, the next step we should take, from these different kind of lizards, is to attempt to force speciation. Regardless, there would seem to be a lot of questions that need answering.
Or, maybe not.
Also reference Reasons to Believe's Science News Flash podcast for April 25, which covered this article. Dr. Fuz Rana notes that the evolved lizard is genetically identical to the original lizard. He argues that the changes seen are micro-evolutionary in nature (with a special footnote regarding the emergence of a new valve in the evolved lizard).
