COLLEGE STATION, TEXAS — Scientists forth Buttermilk Brook arctic of Austin accept begin flint knife blades, chisels and added beastly artifacts lying in a clay band about 16,000 years old — a analysis they say will re-write a above affiliate of age-old beastly history.
For one thing, it is now the oldest and arguably best aboveboard armpit of beastly activity in Arctic or South America — but there's more.
The discovery, by Texas A&M archaeologist Michael Waters and others, pushes aback by 2,500 years the time back acceptable science anticipation bodies entered the New Apple from Siberia and accustomed the built-in populations of Arctic and South America.
"This analysis care to be like a baseball bat to the ancillary of the head," to accomplished theories, Waters said. Added age-old sites in the Americas usually aftermath alone handfuls of artifacts, in soils with ages that scientists altercate about. This armpit independent accoutrement in band afterwards band of soils ample like band cake, the youngest from avant-garde times, the oldest band absolute 15,000 artifacts anachronous to 15,500 years ago.
While Waters is at Texas A&M, abundant of the assignment involving age-old Americans is demography abode in Kansas.
Two able theories
The analysis strengthens the case for two theories that acceptable archaeologists laughed at not continued ago — that the aboriginal Americans came beforehand than 13,000 years ago, and that they didn't airing over a acreage arch into Arctic America from Siberia, but came by bark boats at atomic 16,000 years ago (or continued before) littoral forth coastlines of the Aleutian Islands off Alaska, and again bottomward the bank of Arctic America.
Waters believes they came by boat, hunting seals beside Ice Age glaciers a few afar at a time, actual Ice Age weather, bringing families and pet dogs. He thinks the aboriginal colonies in America sprouted tens of bags of years ago forth the Columbia River basin amid Washington and Oregon, a arena he said archaeologists should re-explore with renewed vigor.
This chance is important to all of us, he said: Best Americans anticipate Columbus should be accomplished in schools, but the aboriginal analysis of America was added ballsy than his voyage, and far older.
