Connecticut: Archaeologists discover a Native American site
Native Americans are generally believed to have originated in Japan around 15,000 years ago. The theory, based primarily on archaeological evidence found at Native American sites, includes stone tools and other artifacts used by First Peoples. They bear distinct similarities to those of the Jomon people, a group that first lived in Japan between 14,000 and 300 BC.
Analysis of their migration across the continent has further added to the theory, with suggestions that Native Americans crossed the Bering Land Bridge until they reached the northwest coast of North America. .
However, the Bering Land Bridge was not a bridge as we know it.
The world was a very different place 15,000 years ago, with much more water locked away in frozen glaciers.
Many places where people once lived, worked and traveled are now under water.

Analysis of ancient teeth could rewrite Native American history.
The tools of the Jomon people (B, D, E, I, J & K) seemed to match the Native Americans (A, C, F, G & H)
The Bering Land Bridge was a strip of dry land, about as large as Australia, between eastern Siberia and western Alaska, making Asia and North America a continuous stretch of land.
He stretched 994 miles from North to south and 2,982 miles from east to west.
The new findings, published in the journal PaleoAmerica, did not rule out that Native Americans would still make this journey across the “Bridge”.
However, analysis suggests that the First Peoples are not descended from Japan.
Tooth analysis debunked the original theory.
Professor Richard Scott of the University of Nevada-Reno and his team of researchers analyzed the genetic and skeletal evidence. They concluded that the similarity of the tools was likely coincidental, as the evidence “does not match”.
The paper, which is set to rwriting Native American history books, analyzing the teeth of the Americas, Asia and the Pacific, including the Jomon people.
Professor Scott said: “We found that human biology just doesn’t match archaeological theory.
“We don’t dispute the idea that ancient Native Americans arrived via the Pacific Northwest Coast – only the theory that they originated with the Jōmon people in Japan.

Genetic analysis suggested little connection between the Jomon (IK002) and Native Americans
“These people, who lived in Japan 15,000 years ago, are an unlikely source for Native Americans. Neither skeletal biology nor genetics indicate a connection between Japan and America.
Professor Scott and his world premiere The team speculated that the most likely source of First Peoples “appears to be from Siberia.”
Only seven percent of Jomon tooth samples could be linked to First Peoples. Genetic analysis reports a similar trend.
Co-author Professor Dennis O’Rourke said: ‘This is particularly clear in the distribution of maternal and paternal lineages, which do not overlap between early Jōmon and American populations.
Footprints made over 21,000 years ago.
“Furthermore, recent studies of ancient DNA from Asia reveal that the two peoples split from a common ancestor at a much earlier time.”
Professor O’Rourke concluded the Jomon population represents “one of the least likely sources for Native American people of any non-African population”.
The team noted that caution is warranted because the only tooth and DNA samples available from the Jomon people are less than 10,000 years old, which does not predate the arrival of First Peoples in America.
They added, however, “We assume they are valid proxies for the nascent Jomon population or people who made stem stitches in Japan 16,000 to 15,000 years ago.”
Newly discovered footprints in an ancient lake bed have further bolstered the idea that Native Americans did not originate in Japan. Dating to between 23,000 and 21,000 years ago, the footprints were discovered in what is now White Sands National Park in New Mexico.
Dr Sally Reynolds co-wrote the team that confirmed the footprints were made by humans. She told IFLScience that the results confirm that the first migrations would have crossed the Bering Land Bridge.
The discovery sheds new light on the arrival of humans on the continent. Dr Reynolds said: “This means humans migrated to the Americas much earlier, but still by the same route.”
It remains to be confirmed if the footprints are definitely related to Native Americans, it should be noted.
The full results of Professor Scott’s team have been published in the journal PaleoAmerica.
