Well of course! I am surprised that someone admitted the truth about the biggest lie in north american anthropology and it just goes to show you how politicized the scientific community has become. Its why any remains are immediately re-buried or cremated so that any anthropoligical evidence that points to anything other than indians being of victimhood class.
"Native American" isn't really a term that identifes race. I'd say it's quite likely that BOTH groups of people were here at the same time. Hell,one or both could have originated here,and the while ones migrated to what is not Japan."The Americas" is one big-ass piece of real estage.
