Cultural artifacts give 100% support for Klevius theory.
Keep in mind that "out-of-Africa" babblers refer to pre-human genes! We are also genetically related to monkeys, fishes, grass etc, but what's the point of mentioning it all the time while confusing it with what made us truly humans, i.e. the single species we are today?! Yes, we are all out-of-Gondwanaland aren't we! Btw, due to late tectonic movements there was no African continent when the hominids evolved! Africa was part of Asia!

The Denisova cave is within the range of what reasonably might be interpreted as the mainland of M45 divergence.

Note that all the Homos that already occupied Africa/Eurasia had a low capacity brain structure as is evident from cultural comparisons. Even the barely one meter high "Homo" floresiensis (which isn't a Homo at all because of, among other reasons, its much more effective brain) with less than a third of Homo erectus brain size, used fire & tools etc!

Note what Klevius terms the grey "bastard belt" where the Northern mongoloids genetically clashed with archaic sapiens!
The continuing & unsubstantiated but politically correct babbling of Africa as the cradle of human evolution is an equally scientifically disturbing phenomenon as was Eurocentrism a Century & so ago! Yes, "Africa" or let's say the Congo river system, may have played an important role in the ape, as well as the Homo eviolution. However, humans evolved outside Africa (because Africa wasn't cold enough) & entered Africa from the North, if we are to believe genetics & physical anthropology glued together with some intelligence!
Btw, although Africa's Rift Valley etc. is an all time open superstore for anthropological finds (ask Richard Leakey - I did) the really interesting part of Africa, the Congo river, hasn't hardly been touched upon so far!
Klevius first comment on the mtDNA report from the 40,000 yr old child finger found at the Denisova cave in the Altai region of Siberia:
With the exception of Neanderthals the number and genetic relationships of other hominin lineages are unknown. However, for the first time a complete mtDNA sequence has been retrieved from a bone excavated in 2008 in Denisova Cave in the Altai Mountains in southern Siberia. It represents a hitherto unknown type of hominin mtDNA that shares a common ancestor with anatomically modern human and Neanderthal mtDNAs about 1.0 million years ago. It may appear to derive from a hominin close to that of the ancestors of Neanderthals and of modern humans. However, more probably it belongs to, or may even be the sole late ancestor lineage of us. When the new human spread from Southern Siberia to East and West they got diluted by already existing Homos so that the eastern branch kept its more mongoloid characteristics while the western branch mixed with more Caucasoid like Homos.
The stratigraphy of the cave where the bone was found suggests that the Denisova hominin lived close in time and space with Neanderthals as well as with modern humans.
This all fits well in the overall pattern of Klevius theory Out of Africa as "pygmies" and back again as "mongoloids"! This theory which is neither out of Africa nor out of Asia, is the first to unlock a rigid speciation stalemate that has made us steer at Homo's big skulls all the time instead of checking if they really did anything worth mentioning proportional to their brain size. Even before Homo floresiensis was repoted Klevius went the other way & introduced the combination of hybridization & a smaller albeit more sophisticated brain developed in a more jungle like environment among apes & was transmitted via hybridization to small ape like Homo relatives whose genes were then slowly transported to the North where they filled bigger heads in a much more challenging albeit also much more protein rich environment.
Did you know that we don't have any usable fossils from chimpanzees, only a few 500 kyr teeth found in the East African Rift Valley?!
Sally McBrearty commenting on what she thinks is some chimpanzee teeth found way outside their normal habitat: "This means we need a better explanation of why and how chimps and humans went their separate evolutionary ways. The discovery that chimps were living in semi-arid conditions as well as in the jungles seems to blow apart the simplistic idea that it was the shift to the savannah that led to humans walking upright."5
Klevius comment to Sally McBrearty's comment: Maybe it wasn't a chimp ancestor after all but rather a "chimp" descendant!
