Our planet was very different 100,000 years ago, and if we could survey that time, we would be astounded by the human diversity across its surface. To enumerate what little we know with certainty, there were at a minimum: modern humans, Neanderthals, at least three to four varieties of Denisovans, and two pygmy Homo populations in Southeast Asia. Likely there were still remnant Homo erectus in Southeast Asia as well, and other diverged lineages within Africa, and a new Homo in Nesher Ramla, Israel, in the Middle East with affinities to Neanderthals.
