[Aztlan] THE BULK OF THE AMERICAS POPULATED BY ONE SIBERIAN GROUP

[Matt Velasco]

Hello all,

I just read the Science review on Late Pleistocene dispersal and I had a
question.  The general conclusion is that humans migrated into the New World
around 15 ka (p. 1501).  Goebel et al. then cite Monte Verde as evidence of
human presence in the Amercias around 14.6 ka.  My question: under a rapid
dispersal model, how likely is it that humans moved from Beringia to South
America in such a short amount of time.  The authors seem to overlook this
detail, as I remember Monte Verde being used as evidence for an pre-LGM
movement into the Americas based on its early date alone.  Any insight?

Thanks,
Matt
