How Humans Landed In The Americas Might Not Be So Simple
New genetic research links tribes from the Amazon to natives of Australia and New Guinea.By Ryan Biek | July 22, 2015
New research from Harvard is putting a wrench in the prevailing theory about where native North and South Americans came from.
For years, many researchers believed a single large wave migrated through Eurasia and modern day Alaska to populate the Americas roughly 15,000 years ago.
But now, genetic analysis from skeletal studies shows some Amazonian tribes share more in common genetically with native populations in Australia and New Guinea.
