Good post.
Another example: SW cliff dwellings were a direct defensive response to cannibal invaders from the south, via the meso-American diaspora. Evidence of this is confirmed in genetic analysis of coprolites in southwest middens of the time of invasion. The last I visited there is still no mention of this at Chaco Canyon. Further, certain native American tribes currently still deny this science.. They consider themselves direct ancestors to the Anasazi, who 'survived' the invasion .
