Evolution's new wrinkle: Proteins with cruise control provide new perspective

But Darwinian evolution was doing fine in terms of explaining things before this "feedback" was found. Darwinianism fine with or without the find.You can hardly loose!Edited by iano, : No reason given.

Science progresses, and formulates increasingly accurate explanations as new data arise.Why do you have a problem with that?

Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.

Actually, it would be quite easy for "Darwinism" to lose! If physically similar species had significantly different genetic codes, or if they even used different tRNAs to transport amino acids to the protein making ribosomes, or if a breed of horses was found that had PVC pipes for transporting blood and a plastic bellows for lungs, or if it were found that the so-called Cambrian explosion really did happen in a few years, or even in a few thousand years (it occurred over a period of several tens of millions of years), then the Darwinian theory would have to be rejected, or at least radically modified.Iano, I know that as an evolutionist yourself you detest reading the dimwitted crap posted on creationist sites, but if you could overcome your aversion to that nonsense for a few minutes, you will find a large number of proposed tests and purported facts to challenge the Darwinian theory of evolution, showing just how easy it would be to disprove that theory if it in fact wasn't valid. That the theory has met all these challenges, and many more intelligent ones put forward by real scientists, explains its broad acceptance in the scientific community.

Hey Coyote, It seems to me that about a year ago, a topic on diversity discussed the question of the rate of mutation evolving. The idea was that there would not be too much variation (interferes with finding mates) nor too little (reduces survival in hard times), and that this was variable due to environment - the Goldilocks solution (and part of the why everything seems perfectly made to suit life as we know it).We also know that bacteria can change rates of mutation when under stress, so this just moves the concept into multicellular systems.Enjoy.
