It used to be "settled" but there is some dissent. I was taught in college that the evidence supports three waves, as supported by linguistic, genetic, and physiological (like dental morphology) differences. First wave of Paleoindians (anywhere from 12000-9000 years ago), second wave of Athabaskans (don't remember, I think like 5000 years ago), and third wave of inuit type peoples relatively recently. The Athabaskans types are limited to northwest North American and pockets in the US Southwest (the Apache were Athabaskans, genetically distinct from other tribes of the area). The Inuit type is thought to have migrated by boat along the Arctic Circle. The first wave type is present across North and South America. I found this link that summarizes the debate, originally published in Science. unl.edu My main interest was in North American lithics, so I got pretty into origins as well. It's all really interesting, to me at least. :) Derek
