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

All four involve out-of-Africa, and for a model to be parsimonious with the available data, it's clear that the out-of-Africa/Replacement/master race bias has to be dumped on its ass.

Dispersed Out of Africa Earlier Than Thought

A staff member of mine was from Kenya. I remember him saying "in Africa, like is hard." I suppose that could explain it all.

It’s a jungle out there.

This is the kind of thing I frequently point out to people in debates about global warming. How often do we see news items where scientists are surprised at some new discovery that “turns everything we thought we knew on its head?” Therefore, how can there be such a things as “settled” science, or a “consensus?”

Just out of curiosity, how did the early “beachcomber” humans get from “Africa”to the Arabia Peninsula? Once there, how did they survive the journey?

Following the Nile makes a lot more sense. Just the small matter of food & water, you know.

Probably got one look at Meryl Streep and Robert Redford and said “We’re outta here!”

“”It is really exciting that our results point to the possibility of a multiple-dispersals model of modern humans out of Africa,” Harvati said. “A multiple-dispersals scenario, with earlier modern humans leaving Africa as early as 130,000 before present, can perhaps account for part of the morphological and genetic patterns that we see among modern human populations.”

That’s the hypothesis I like. Part of the problem with evidence is likely caused by the fact that a lot of the coastal route is under water now. There is a lot out there to yet be discovered.

Booted out by Harry Reid, the EPA and the BLM, no doubt.

a "beachcomber" route

Now sit right back and you'll hear a tale, a tale of a fateful trip...

Earliest recorded history of “white flight”.

Over the past several million years, the planet has had numerous, separate ice ages. Some of these, like the last one, were so extensive and had so much ice that world wide, sea levels dropped over 300 feet!

At those times, the straights at the exit of the Red Sea would have only been a few miles across, and the distant land could be easily seen from either side. I can image people, just like they are now, were very curious as to just what was on the other side. Logs float, and can be tied together to make rafts.

The rest, as they say, is prehistory!

Just what is the proof that humans began in Africa???? Maybe they earlier came TO Africa from somewhere else.....

I just do not buy all this history channel and scientific claims. People can make studies turn out the way they want and manipulate data.

I won't post this, because it is pretty big, however, here is a map of the Earth with a sea level 394 feet (last glacial maximum) LOWER than it is now.

Ice Age Sea Level Map

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 used to have a map of the same but 5 times larger on my old web server, but I cannot remember the link, and gave the server to someone else to administrate!

And besides the fact that the ancestors of everyone in the world spent most of the last two million years on dry land that is now below sealevel, there’s no reason to think these hypothetical routes had a bunch of one-way signs along them.

Everyone who takes the time to read it and post a reply does.
