People from North America moved into South America in at least three migration waves, researchers report online November 8 in Cell. The first migrants, who reached South America by at least 11,000 years ago, were genetically related to a 12,600-year-old toddler from Montana known as Anzick-1 (SN: 3/22/14, p. 6). The child's skeleton was found with artifacts from the Clovis people, who researchers used to think were the first people in the Americas, although that idea has fallen out of favor. Scientists also previously thought these were the only ancient migrants to South America.
But DNA analysis of samples from 49 ancient people suggests a second wave of settlers replaced the Clovis group in South America about 9,000 years ago. And a third group related to ancient people from California's Channel Islands spread over the Central Andes about 4,200 years ago, geneticist Nathan Nakatsuka of Harvard University and colleagues found.
One mystery produced by the research was genetic markers were found in remains in Brazil that are shared with Australian Aborigines, but by no remains found between them in the Americas.

people trying to make their god be like themselves is not very related to this story. Just because propagandists say that *all* "native americans" or even more presumptuous "first nations" peoples were from Mongoloid migrations doesn't mean it's true. 11k yrs? that's all you got? there could have been worldwide near extinctions of humans in previous thousands or even millions of years for all we know(ancient aliens style). or less fantastically, there very well could have been migrations of Caucasoids that predated the Mongoloid migrations and/or coexisted with said migrations. Caucasoids might have been sailing the seas/coasts setting up shop globally while the mongoloid races were still dependent on land bridges. (pyramids everywhere that have since been claimed by subsequent populations or their slaves and/or a mixture that remained. none of the scientists depending on establishment money for their research/propaganda look into/talk about any of that shit) the PC version of history is that these mongoloid peoples were here in their "native homeland" minding their own business when evil Uncle Cracker showed up to slaughter them. who's to say that the mongoloid migrations didn't find Caucasoid populations (maybe only in pockets and rarely?) and either breed them out over time, or defeat them in war as well? Who's to say that kings of european countries taking over "native american" land didn't have knowledge of previous wars? maybe it was partially about revenge? it wouldn't be the first time. maybe it was revenge for the hun invasion/near destruction of europe? the fact is, that the Aryan race (specifically) is trying to be disappeared from history and the future (usually by brainwashed white people), and this "europefying" is many times a response to that, not necessarily the other way around. there are also "black nationalists" (any black "nut" who questions their history according to some, i'm sure) who claim that there were "Native Americans" of African decent. i don't rule that shit out either. in fact, i have questions, but no time to research it. there's a lot we don't know (purposely?) about ancient human history and dates of things to be such a douche.
