What I was defending against was just that everyone was saying how genetically diverse we are as humans and how 50-60 thousand years can't explain this. What I was hoping to present was someone's opinion that we are not at all as genetically diverse as we should be if our human origins were say millions of years old.
As far as I know, the science bears you out on that, at least. We only have the genetic diversity of a species that experienced a bottleneck some 80,000 years ago, which is why I thought it was weird for JonF to claim that we haven't experienced any bottlenecks in a million years.
Aside from what I posted isn't it also true that modern humans only differ from one another by 6 or so base pairs?
I'm not sure what you mean. The difference between you and I is way, way more than six base pairs. On the other hand the difference between you and your parents may be less than 6, even.
The number of mutations (effacious or not) - which may be what you're talking about with base pair differences - for the average human, I've read here, is somewhere between 5 and 50, or something. (I've heard a
lot of figures, to tell you the truth.)
