What is "exactly even?" Homo Sapiens went through a genetic bottlenecking event sometime in the last 100K years, with the population reduced to a couple of thousand breeding individuals, so we're going to be fairly close genetically. Up to about 50K years ago, there were at least three human species on the planet (Homo Erectus, Homo Neanderthalensis and Homo Sapiens). If the Flores Man thing turns out to be another species then we're up to four (I doubt it will, though, but one must keep an open mind). Unfortunately, all Homo species had pretty much come to fill the same niche in each of their environments; as Homo Sapiens spread out he displaced the others who eventually went extinct.
Not that I expect you to actually assimilate the information in this post, but at least the lurkers will see it.
Do you believe in a global "near extinction" theory?
