Did Native Americans Originate from Japan?

The biological evidence "simply does not match up" 

with archeological finds.

Native Americans may not have originated in Japan as previous archaeological evidence has suggested, according to a new study of ancient teeth.

For years, archaeologists had predicted that the first people to live in North America descended directly from a group called the Jomon, who occupied ancient Japan about 15,000 years ago, the same time people arrived in North America around 15,000 years ago via the Bering Land Bridge, a strip of land that previously connected Russia to North America before sea levels rose above it. This theory is based on archaeological similarities in stone tools, especially projectile weapons, found in Native American and Jomon settlements.

However, the authors of the new study say this scenario is highly unlikely because the biological evidence "simply does not match up" with the archaeological findings, according to a statement from the researchers.

"The Jomon were not directly ancestral to Native Americans," lead author G. Richard Scott, an anthropologist at the University of Nevada, Reno, told Live Science. "They [the Jomon] are more aligned with Southeast Asian and Pacific groups than with East Asian and Native American groups."

Instead, the researchers suspect that Native Americans descended from a different group living somewhere in East Asia, although a lot of uncertainty remains about exactly where and when those ancestors lived.

An archaeological theory

Scott and his colleagues began their study because they were unconvinced by the main argument linking Native Americans with the Jomon — the stone tool similarities, they said.

"The artifact similarities between ancient Jomon and at least some of the earliest known Native American sites lie in the stemmed projectile points," co-author John Hoffecker, an archaeologist at the Institute of Arctic and Alpine Research at the University of Colorado Boulder, told Live Science. These similarities led previous researchers to suspect that the knowledge to make those tools had been passed down from one culture to the other, he added.  READ MORE...
