: How would an evolutionist explain this? Remine postulates that in 10,000,000 yrs the human species can substitute 25,000 expressed neutral mutations, about .0007% of the genome. If this is true, given the 2% difference between humans and chimps, then our common ancestor lived about 20,000,000,000 yrs ago. ***I think that the calculations are based upon averages of mutation rates, however, I have heard of an offshot theory I guess you call it that hypothosises that there are times in which some of the mutations are gigantic, and that the effect is like bypassing millions of the "everyday" common distance of a mutant change. Also, it may be that environmental changes speed up the mutation rate at times as well as create conditions for the mutation to occur in many individuals along the same lines (if not identical) thereby multiplying the application of the mutation geometrically compaired to the common single mutant/generational adaptation system. And there is always the chance that both that the mutation is both great in itself (amount of change) at the same time that it is widespead in individuals which would increase the effect outragiuosly. Anyway, what exacly is it that you propose, what are we and how did we get here in your opinion? |
