Not only did we inhabit the AMERICAS first, We inhabited Asia as well.
At about 35,000 B.C. a group of these African Chinese; later known to us as the Jomon, took this route and entered Japan, they became the first Humans to inhabit the Japanese Islands. Later, another group; Known to us as the Ainu, followed.
Although we do not have “Ancient life-like” depictions of the Jomon and Ainu, we do have pictures of members of their former migratory group – their genetic cousins, the Andaman Islanders of the Indian Ocean, (Just off the coast of Burma and Thailand). Oddly Indians were Not part of this group. Today, their genes can still be found in 40% of modern Japanese, as well as Mongolians and Tibetans. Genetic testing, specific to Xia, Shang and Olmec, as far as we know, has not yet been done.
