| OooSnap said: Some have brought up the Lenski experiment. It is emperical, empirical evidence for evolution, right? Not at all. Interesting example however recent research shows it is just another example of degeneration or "deevolution": "The gene that mutated to enable bacteria to metabolize nylon is on a small loop of exchangeable DNA. This gene, prior to its mutation, coded for a protein called EII with a special ability to break down small, circularized proteins. Though synthetic, nylon is very protein-like because inventor Wallace Carothers modeled the original fiber based on known protein chemistry. Thus, after the mutation, the new EII protein was able to interact with both circular and straightened-out nylon. This is a clear example of a loss of specification of the original enzyme. It is like damaging the interior of a lock so that more and different keys can now unlock it. This degeneration of a protein-eating protein required both the specially-shaped protein and the pre-existence of its gene. The degeneration of a gene, even when it provides a new benefit to the bacteria, does not explain the origin of that gene. One cannot build a lock by damaging pre-existing locks." http://www.icr.org/article/4089/ |
it's sad how you think these are real sources. the site you are viewing is not a science website. its sources are not peer-reviewed journals but blogs written by layman. even the author is a total idiot.
