A fairly common number given for the rate of mutation in our DNA per generation is approximately 200.Ok now take that 200 and divide it by the 20,000 genes (lower limit) in the human genome (you're gonna get a small number).
Quote:Given our split with chimpanzees was about 6 million years ago that means our DNA has changed about 1% in those years. Chimpanzees DNA accumulates mutations at the same rate of 200 per generation (as does all DNA based life - all life except Christian fundamentalists). That would mean our DNA should be approximately 2% different. The difference is measured at 1.4% but why the difference? Natural selection has weeded out the "bad" mutations and kept those that are either beneficial or neutral.Don't let your imagination run too wild on you buddy. They say we are 96% related to apes BUT we do not even know the function of over 97% of the human genome. So their "proof" that we are relate is that we have 46 chromosomes and they have 48 chromosomes (46/48 is about 96%). Gee talk about intellectual dishonesty.
Quote:BTW, if you don't think 3800 million years is enough time to evolve a "50 trillion cell" creature, you are woefully misinformed. For example, from a naked retina to evolve a complex eye can be done in 400000 steps. Given just one small step made each generation, that would take 4 million years given a 10 year generation.But if you consider the amount of negative mutations vastly outweighing the positive ones you cannot even demonstrate how this process happen other than imagination. Even if that was enough time, there is no evidence to corroborate this narrative.
Do yourself a favor and learn evolutionary theory before making yourself look even more foolish.

All we have been able to prove is that variation whether through natural selection (which extracts form existing mutation) or mutations is limited to producing variation of a certain kind of species resulting in different kinds of that species (never anything totally new even with the alleged time you claim).(April 21, 2012 at 12:02 am)Abishalom Wrote: You're right that probability does not disprove anything. But the main point is that we have no evidence to support infinite variation of a species (that eventually transcends the species barrier) and all the evidence proves that there are clear limits on variation so let's not get off track. Infinite variation is just man's imagination run wild because there are no facts to support it.None of what you are saying makes any since, mostly because of the fact you keep spouting the same thing about infinite variation over and over again. Did you not read anything else that I or Phil wrote in the previous posts about natural selection? Mutation itself is variation and with time and enough mutation there will be infinite variation. It is simple probability. Evolution is proven with very simple probabilistic math and with very simple algorithm called natural selection. There will be a certain point when genes passed on will not be compatible with the parent species. This is when a new species is formed. I said this previously.
