“It is likely that there were at least eight different species of humans on Earth (perhaps even more) between 150,000–30,000 years ago—and they sometimes exchanged genetic material through inter-breeding.”
I would think that if you can exchange genetical material through inter-breeding you would be the same species.
So we have 8 species/subspecies(?). I know sapiens sapiens, neanderthal, denisovan, and flores. What are the other four called, and where were they known? My son had his genetic testing done by Ancestry. He also had me and my husband back analyzed by them. Ancestry does not do Neanderthal. I have shoveled lateral upper incisors as does that son which is suppoed to be a Neanderthal trait. Apperently I have about about 6 to 9% far,far, eastern European (probably from my East Prussian upper class ancestors). Descendents of The Golden Hoard (Mongol). Might I have Denisovan rather than, or in addition to Neanderthal? Does any ancestry service test for both of these?
