biscuit7:I was saying it was false that non-humans are less related than we are
well... i thought it was true
as i understand it, most animals have far more DNA variety than humans. humans are pretty narrow when it comes to DNA (we went through a heck of a bottleneck about 70,000 years ago).
cheetas went through a heck of a bottleneck about 10,000 years ago, much worse than that of humans (it's possible that only one female chettah is responsible for the survival of the species).
so, yes, cheetahs have less DNA variance than we do, but we have a lot less DNA variance than most animals.
i could be wrong. as i said, i'm not an expert on this stuff.
