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.

    dark indians(dots not feathers) have australoid dna(and look like them too). modern science says that this is because of an early migration out of africa with some people passing through india and ending up in australia(basically). the australian aborigines say they have been their since the dawn of the world. if you look at a map of pangea, india is right next to australia. makes you wonder...
