Peter Klevius seems to be the only anthropologist today who isn't confused by incoming new data!
Modern intelligent humans evolved in cold and challenging but also extremely protein rich Siberia where big headed northern Neanderthals encountered (raped) smaller but proportionally more intelligent Homo floresiensis relatives from SE-Asia. As you hopefully already knew, Homo floresiensis resided at the very place where we now see most of genetic Denisovan ancestry. Moreover, what has puzzled all other anthropologists except Klevius, is the fact that despite its extremely small brain, Homo floresiensis managed to make tools, fire, and hunt in a similar way as Homos with more than double its brain size. And although its relatives on the way up through what is now China, became slightly bigger, it was only after having met with Nanderthals (and possibly other archaic Homos) the real intellectual explosion took place, as exemplified by the extremely sophisticated Denisova bracelet. And the reason why this cultural leap got a European bias is that there were 1) bigger Homos (arhaic Homos and Neanderthals), and 2) it was the natural extension of the Siberian protein steppe.
Since 1980, in a letter to George Henrik von Wright (Wittgenstein's successor at Cambridge) Peter Klevius has proposed Central/Northern-Asia as the real point of departure for what we reasonably may call modern humans. Since 2004 Klevius has also presented this view on the web (Out of Africa as bipedal apes and back as global mongoloids) for everyone to contemplate. And nothing has been added to that page since. Why? Because reality has made the job for Klevius. And the overall correspondence is so overwhelming that correcting small details has been unnecessary because it wouldn't have changed anything essential.
First came Homo floresiensis, then the Denisovan and the Neanderthal genome, and now the genetic relation between Europeans and native Americans. All in perfect line with what Peter Klevius has written all the time (1980, 1981, 1992, 1994, 1996, 1998, 2004 etc).
On top of this we have the newly proposed linguistic connection between American indians and Uralic languages. What can Klevius possibly say to all of this?
Well, he could say: Get rid of your bias stupid if you want to get closer to reality (yes, Klevius is an empiricist and not a realist - but that's an other topic - see EMAH)!
So what's the secret behind this theoretical success (also compare Klevius success on AI philosophy on what is consciousness and how the brain works)?
Well, a good brain doesn't hurt but is useless unless it's combined with a rigorous anti-bias approach (i.e. self criticism). To tell the truth, all of this then became quite obvious when applied to what we actually already knew about human migration etc.
Nothing, not even European paleo-art, beats the findings at the Denisova cave in the Altai region of Siberia. Moreover, Denisova is situated exactly where Wells placed the genetic split point from which modern humans spread all over the planet (incl. into Africa).
A modern male Homo sapiens sapiens*. This particular individual belongs to the bastard race that was the result when mongoloids mixed with archaic Homos.
* Peter Klevius contemplating human evolution, consciousness and sex segregation. His father was a Goth from Gothenburg (possibly Sweden's best chess player of his time) and his mother was from Finland and possessed some mongoloid features (she was extremely intelligent - just like her two brothers). Klevius himself may in this context be seen as a step downwards, i..e. in line with an overall progression towards a more diluted absolute intelligence. Klevius half sister (same mother but different father) follows the same trend and scored only 167 on an IBM IQ test long ago.
