New 'Molecular Clock' Aids Dating Of Human Migration History

Researchers at the University of Leeds have devised a more accurate method of dating ancient human migration -- even when no corroborating archaeological evidence exists.

Estimating the chronology of population migrations throughout mankind's early history has always been problematic. The most widely used genetic method works back to find the last common ancestor of any particular set of lineages using samples of mitochondrial DNA (mtDNA), but this method has recently been shown to be unreliable, throwing 20 years of research into doubt...

The new method has already yielded some surprising findings. Says archaogeneticist Professor Martin Richards, who supervised Soares: "We can settle the debate regarding mankind's expansion through the Americas. Researchers have been estimating dates from mtDNA that are too old for the archaeological evidence, but our calculations confirm the date to be some 15,000 years ago, around the time of the first unequivocal archaeological remains.

"Furthermore, we can say with some confidence that the estimate of humanity's 'out of Africa' migration was around 60-70,000 years ago -- some 10-20,000 years earlier than previously thought."

alas, can't use the following one because of copyright restrictions. I'm sure a quick web search will turn up many copies of it though, just not on FR or other conservative websites. Y'know, because that's usually what those restrictions are all about.

These finding have been confirmed by the last remaining survivor of the Americas original inhabitation.

Yawn. I’m still waiting for someone to unearth the Atlantis exit visas.

[SunkenCiv]

There were never any exit visas, alas. Atlantis sank under the weight of a massive wave of illegal immigration.

Oooooooh...

You'll be waiting a long time. Atlantis had an "open border" policy that eventually led to its demise.

[CholeraJoe]

I’ll bet they issued Chariot driver’s licenses to the illegals and let them vote for Proconsul and Senators, too.

[coconutt2000]

Yes. If only the conservative Atlanteans had built that wall, it may have saved them.
