Some races/subraces of men have already gone extinct in the distant and not-so distant past, including such groups as Caucasians in China and Central Asia, Australoids in Southeast Asia and many other groups around the world.

Let me know your thoughts on these lost races of Homo Sapiens, who, although no longer existing in their pure form, still have varying degrees of influence on the modern people groups that succeeded them. Thanks for watching!
