It's official: Native Americans and Siberians are cousins February 23, 2016 Aram Ter-Ghazaryan, special to RBTH After more than a century of
speculation, an international group of geneticists has conclusively proven that the Aztecs, Incas, and Iroquois are closely related to the peoples of
Altai, the Siberian region that borders China and Mongolia.
Land bridge from Asia Scientists already know how humans traveled to the Americas from Altai. "Instead of the Bering Strait there was a land
bridge [30,000 years ago], because during the Ice Age much water was locked in glaciers and the level of the world's oceans was lower," Dr. Balanovsky
Sorry, there was another land bridge other than Bering Strait that I just found out about.
Hey, I just wanted to point out that the land bridge referenced in your citation was indeed Beringea. That's what it means by "instead of the Bering
Strait there was a land bridge". It just means that instead of the Bering Strait, a body of water separating Alaska and Siberia, that there was land
above sea level connecting both continents.
It was actually a pretty temperate ecological niche at the time that there was land there. Edible plants, thriving. Ecosystem and herds of animals
migrating back and forth between the 2 continents. People actually set up shop there and we've found the remains of a couple of sites underwater
showing what appears to be a lengthy period of human occupation of the area.
It was likely the rising sea levels that prodded the people to migrate either east or west and when the more narrow areas of the middle of Beringea
were finally inundated, there was no turning back so South they went. Genetic data seems to show that a little earlier than this, as well as while
Beringea was being inundated and people were moving south into the Americas, there was also a water born migration along the coast via boat.
So while the story is certainly still expanding and the time frame that people made that way into the Americas keeps getting pushed back with new
evidence, it all still appears that the northern entrance to the Weatej Hemisphere was indeed the route taken. Interestingly though, there is
evidence that some people headed down the coast to S. America first and then later back migrated North.
The story keeps getting more interesting and more detailed, but the basic facts at the crux of it still hold true and are reinforced and corroborated
by new archaeological finds as well as recent genetic data from recently deceased people to ancient DNA from people like the "Kennewick Man" adding
some new details by uncovering his MtDNA and Y haplogroups.
