Americas settled 15,000 years ago

A consensus is emerging in the highly contentious debate over the colonization of the Americas, according to a study that says the bulk of the region wasn't settled until as late as 15,000 years ago.

Researchers analyzed both archaeological and genetic evidence from several dozen sites throughout the Americas and eastern Asia for the paper.

The article, which is published in tomorrow's issue of the journal Science, shows that the first Americans came from a single Siberian population and ventured across the Bering land bridge connecting Asia and North America about 22,000 years ago. The group got stuck in Alaska because of glacial ice, however, so humans probably didn't migrate down into the rest of the Americas until after 16,500 years ago, when an ice-free corridor in Canada opened up.

That is a long time (5500 years) to be stuck in Alaska in a pcoket between the glaciers. It is interesting that they did not evolve into a sub-species of human during such a long time of isolation.

Since you use the term "subspecies" don't you mean "devolve." Sorry, just nitpicking.

But anyway, that's not nearly long enough to develop a new species. There may be some "genetic drift" but even that would take much longer -- and, manifestly, there was no genetic drift because no such abberations exist, or have been found.

I alway find this subject fascinating. I still think there is some debate about sea-faring people who may have landed in south america, bring in new people from some other way than the Siberian land bridge.

I think 5,000 years is enough time to get a good running start on a population becoming a new species.

I also believe that people got to the New World (Americas) through many different paths. It is just that Most of the people who are called Native Americans are decended from those Alaskan travelers. Genetic sampling supports it.

Stop the "consensus" garbage. If you are not 100 percent sure then shut your pie holes! Listen to me, even my voices agree that none of thes scientiests are listening ... it's a consensus!!!!

There is nothing that is 100%. It is not even 100% that you or I are even alive. It is all a matter of perspective.

In just about everything in life we have to decide what to do and "The Concensus" is usually the easyest and fastest, and usually... the most correct.

Fortunately, the actual scientific consensus predates the modern think tank's version. I was up in Old Crow Flats in 1991 and I met some of the archaeological teams performing studies up there. A few of the guys even believed that 60,000 years seemed more accurate.

Thanks for that link Digital.....I've never liked the "official" version of homo sapeins in the Americas....

I can understand that they may have come over at 'different stages' or times(?) But...

All off the original link/site bar one sub-link...

...according to a study that says the bulk of the region wasn't settled until as late as 15,000 years ago.

...so humans probably didn't migrate down into the rest of the Americas until after 16,500 years ago...

Some geneticists had also previously suggested that the migration across the land bridge could have occurred as early as 30,000 years ago.

Modern humans spread across the land bridge about 22,000 years ago, according to the new article.

"New World Settlers Took 20,000-Year Pit Stop"

Siberian population and ventured across the Bering land bridge connecting Asia and North America about 22,000 years ago.

According to the new theory, humans heading east after leaving Asia about 40,000 years ago were blocked by two huge glaciers that met at present-day Alaska.

''For example, there are some "puzzling anomalies" in the Alaskan archaeological record dating back to before the glacial melt, he pointed out.''

lol!!!

Just a crazy thought, why don't the (Scientists/Archaeologists/Researchers) try & work side by side with the Native American Elders/Historians They may actually know more than we think? The they might finally resolve this once & for all, or at least get the figures a little more accurate?...
