... chimpanzees, which is to say that humans and chimps carry exactly the same version of the gene. Another useful example is extinction, in which the frequency of all alleles in a species go from some to none. What the creationist is actually talking about here is something that would falsify evolutionary ...

... nerves speeds or brain speeds, if they had faster brains with low capacity; and if fast enough (relativity) then would they hear sound in a lower frequency? could it mean they can see light in a different colour? my question is; if the brain increased in speed, would everything looked like they ...
