A number of natives of the Amazon rainforest may partly descend from peoples in the Pacific, researchers say.
It remains a mystery as to when and how this genetic signature from an Australasia group in the Pacific they call "Population Y" made its way to the Amazon, scientists added.
Most genetic studies have suggested that all Native Americans analyzedto date can trace much or all of their ancestry to a single common origin — a population from Eurasia that probably migrated to the Americas more than 15,000 years ago, back when lower sea levels exposed the Bering land bridge known as Beringia that connected
the continents. Some Native Americans from North America and the Arctic may also trace other parts of their ancestry to more recent waves of migration.http://www.livescience.com/51618-mysterious-population-y-bred-with-amazonians.html
