Is that now > considered to be incorrect? They are trying to define different species by genetic distance. They want to claim that limited gene flow that produces two populations as different as modern humans and Neanderthals should be designated as different species. This allows geographically separated populations to be called different species if they are different enough in their population genetics. It would likely be good news for racist segregationists. Just think of how close to being a different species the New Guinea populations are that are over 7% Denisovan and 3% Neanderthal compared to African Modern humans that never left Africa. Denisovans are even less genetically related to African modern humans than Neanderthal. Both Neanderthals and Denisovans left Africa around 800,000 years ago, but Neanderthals interbred with Africans a couple of ice ages ago, so they were already more closely related to the modern humans that made it out of Africa during the last ice age.
