We need to investigate the large historic African presence in Asia, especially in India where there are 100 million people of partly African descent. We need to investigate the African presence in the pacific islands. There are entire nations made up of people of African extraction. We need to investigate Australia before the British destroyed its black inhabitants. Tasmania was black before the British destroyed every man, woman and child on the island.
This one would be very interesting. I've been to many Asia countries and the physical make-up of Mongolians (Eastern China), nKoreans, and a few others (all those "...istans") has had me wondering just how far ancient explorers from Africa went.
Not only the physical similiarities but a lot of the cultural aspects as well. Even if you did the research, I doubt anyone would be willing to admit or except the findings.
