African Australians in the Amazon TODAY as ancient origin of humans in the Amazon hunting Mastodon

Although the Aboriginal Australians aren't technically considered Melanesian, the groups that initially populated Papua New Guinea and Australia probably arrived from Southeast Asia at roughly the same time.
So you have that. Then you have this:

Indigenous peoples in the Amazon and Australia share some ancestry

Strewth – Australian genetic link to founding of the Americas

strewth. (Britain, Australia, New Zealand) A mild oath expressing surprise or generally adding emphasis.

In other words - Africans spread around the world.... from our original human culture - the San Bushmen culture....
 The genomes show this “Australasian signal” is more than 10,000 years old. So where did it come from?

 There was an earlier dispersal out of Africa - into Australia all the way back to 70,000 years ago - vid - BEFORE humans went into Europe

  how can you say that genetics is better than cranial metrics? he is asked....

  Crap in a Cave older than Clovis!

  Native Americans...are not very closely related to Siberians...there's no really very good traces of them in the Old World... Well, basically, by chance, we were working on a skeleton close to the Mal'ta,.. Here we sequence the draft genome of an approximately 24,000-year-old individual (MA-1), from Mal'ta in south-central Siberia.. which is 24,000 years old. What was very surprising about the genetics here is that this individual is very close, genetically related to Northern Europeans and also very closely related to Native Americans.... But NOT very closely related to East Asians... This was of course very exciting results because it showed us that the distribution of human groups in the past, ...very different than today! 

Approximately one third of all living Native Americans seems to be very closely related to this Mal'ta group... a Siberian Upper Palaeolithic population related to modern-day western Eurasians.

  could explain why several crania from the First Americans have been reported as bearing morphological characteristics that do not resemble those of east Asians.

  Professor Kelly Graf from the Center for the Study of the First Americans (Texas A&M University), who together with Professor Willerslev did the sampling, adds, "Our findings are significant at two levels. First, it shows that Upper Paleolithic Siberians came from a cosmopolitan population of early modern humans that spread out of Africa to Europe and Central and South Asia. Second, Paleoindian skeletons with phenotypic traits atypical of modern-day Native Americans can be explained as having a direct historical connection to Upper Paleolithic Siberia."

  People have been in Europe for about 45,000 years....so the further northeast you go, the more hunter-gather you go, genetically speaking, so the most hunter-gather like today is Russians or Finns...and then for the farmers it's just the opposite - the larger interpretation here is where there's a movement of people here from the south into the north, that is having a lot of sex with southern Europeans and less sex with Scandinavians [hunter-gatherers] and when they reach Eastern Europe, they don't want to have any sex at all...

  Hunter-gathers of Europe probably look a little bit like this guy here, very dark skin, blue-gray eyes - seems to be dominant. It's really first with the Yamnaya expansion [circa 3000 BCE] you get this light skin and brown eyes...and the height - before that we were really short,...

  Climate is a really important driver of change for these big animals [mega-fauna]. .. there's definitely an impact of climate. In several cases, humans do not overlap at the time where these animals go extinct - [muskox for example]...what seems to be the major driver here is the climate. What about the climate? The vegetation changes...I went and drilled more than 200 permafrost samples, we dated them and retrieved the DNA and reconstructed the vegetation changes... Between 30,000 years - you have much more diverse vegetation..... around 20,000 years ago at the coldest period of the Ice Age you see a massive drop in diversity...the last glacial maximum....but still a dominance of these forbs. But then it becomes warm again and people thought it would return to the previous vegetation. No, shrubs instead and these forbs declined dramatically. One of the key arguments...they had survived before...so what was so special? the vegetation had changed. We also got access to stomach contents and could DNA of the composition of the diet and the dominant part of this diet is these forbs...

So it's really the vegetation change and decline of the forbs that's causing the major problems and driving extinction...
