well, if kennewick man was japanese, and if the other first americans were australian aborigines (as other threads have said), i guess we should split the country in 2 and give half to the japanese and half to the australians.
the whites and native americans will all have to go back to wherever.
Ummm... That makes zero sense. If you took a sample of my DNA, since I am Iroquois, you'd find that my ancestry comes from the Jomon, the prehistoric people of Japan... However, if you sampled Seminoles and other Floridian indians, you'd probably find they shared similar ancestry as Eskimos - they both are a later stock of the Jomon.
Then, you study some of the Athabascan groups, yo'd find they are decended from a prehistoric peoples from what is now China, and maybe if you checked Algonkian peoples you'd find they may actually have some Prehistoric European ancestry...
However, since the ancestry is thousands of years old, what you say makes absolutely no sense... :0)
