I assume most of you have heard the infamous creationist claim that evolution "cannot produce new information". Well, that argument just took another beating. Check it out,
The Origin of Vision.
"We now have a time frame for the evolution of animal light sensitivity," said study leader David Plachetzki, a UC Santa Barbara graduate student. "We know its precursors existed roughly 600 million years ago.
These findings, detailed in a recent issue of the online journal PLoS ONE, counter arguments by anti-evolutionists that evolution can only eliminate traits and cannot produce new features, the authors say.
“Our paper shows that such claims are simply wrong," said co-author Todd Oakley, also a UC Santa Barbara biologist. "We show very clearly that specific mutational changes in a particular duplicated gene (opsin) allowed the new genes to interact with different proteins in new ways. Today, these different interactions underlie the genetic machinery of vision, which is different in various animal groups.”
