Humans May Have Dispersed Out of Africa Earlier Than Thought

Scientists have suggested the exodus from Africa started between 40,000 and 70,000 years ago. However, stone artifacts dating to at least 100,000 years ago that were recently uncovered in the Arabian Desert suggested that modern humans might have begun their march across the globe earlier than once suspected.

Out of Africa models

To help solve this mystery, Katerina Harvati, a paleoanthropologist at the University of Tübingen in Germany, and her colleagues tested four competing out-of-Africa models.

• one involved a route northward, up the Nile River valley and then eastward across the northern end of the Arabian Peninsula into Asia
• the other involved a "beachcomber" route along the southern coast of the Arabian Peninsula into Asia
• Two other models involved multiple dispersals, with both models involving routes along the northern and southern ends of the Arabian Peninsula
  • one involved connections and gene flow between these routes
  • the other did not

...The researchers found that both the genetic and skull data supported a multiple-dispersal model involving several migrations.

Part of that is coverage, i.e., straw men, the rest is careerism. Science is a method, not a body of knowledge.

“You mean the Sahara Desert?”

“Sure — now!”

And thanks, I’m filing that again. :’) I think I lost it last time.

Political Science.

[dennisw]

I am suspicious of the out of Africa theories, They are too convenient for the left-politically correct.

There are other theories such as SE Asia also being a place for human origins. My opinion is these theories are based on thin evidence and are perpetrated to get Federale government grants

"Looks like the Red Sea was actually closed at the southern end, so theoretically people could have simply walked across from Africa into (present day Yemen) the Arabian peninsula."

I've often considered that the Red Sea was completely dry. The Mediterranen would have seriously decreased water levels then.

Eerything changed about 7,500 years ago

Thanks, me too!

The above average intellect gene. Who knew?

Bucky Fuller believed in the out-of-south-asia proposition.

And there are finds in Australia that come close to pre-dating anything in Africa...

[Bernard Marx]

Therefore, how can there be such a things as “settled” science, or a “consensus?”

There can't be. Science is open-ended and new discoveries or evidence can change a theoretical model in an instant. Consensus is a term that should never be applied to the scientific method.

I’ll let the “scientists” play around twisting their mustaches and batting each other’s arses.

Just takes a child looking at Google Earth to tell that there was once just one big Super Continent. Something happended and it was broken up and spread out.

Anything in our history books that might explain any of what is clearly seen?

[SunkenCiv]

Yeah, a child could come to that conclusion if sufficiently misled.

[SunkenCiv]

The problem with whole thing is, there’s nothing but morphology to go on, and the existence of fossils in a few places in Africa doesn’t mean there are no fossils elsewhere, nor does it mean that there was no one living anywhere else who just died and failed to leave fossils. :’)

Listen, Bub, it’s all roads lead out of Africa or you lose your funding and we strip you of all your degrees. Got it!?

[SunkenCiv]

AKA dance with the one whut brung ya.

[BobL]

Can you blame them for leaving, considering the Blood Diamonds, Ebola, AIDS, Colonialism, corrupt government, Islamic Slavery, and God knows what else, was on its way there?
