Humans May Have Dispersed Out of Africa Earlier Than Thought
LiveScience ^ | April 21, 2014 | Charles Q. Choi

Posted on 04/21/2014 4:04:04 PM PDT by SunkenCiv

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.

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.

“”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.

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!

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.

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

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?

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. :’)

Thanks for the map. Any idea if the “green areas”are accurate, i.e. no deserts? (except, of course, under the ice sheets.)

If there was a land bridge, that route from Northern Kenya & Ethiopia would be easier that through the mountains of Ethiopia.

Anyone have a map of what the Rift Valley volcanoes were doing at the time? Increased volcanic activity may have herded folks to the NE toward the Arabian Peninsila.

This is interesting:

“The coastal route around the western Mediterranean may have been open at times during the last glacial; speleothems grew in Hol-Zakh and in Nagev Tzavoa Caves. Comparison of speleothem formation with calcite horizons suggests that the wet periods were limited to only tens or hundreds of years.[6]

From 60–30 kya there were extremely dry conditions in many parts of Africa.[7]
Last Glacial Maximum

An example of the Saharan pump has occurred after the Last Glacial Maximum (LGM). During the Last Glacial Maximum the Sahara desert was more extensive than it is now with the extent of the tropical forests being greatly reduced.[8] “

Bingo! One of the problems with the out of Africa Theory is that it makes no sense. You find a few bones in the Afar region and we instantly originated there.

What happens if we find bones else where, which seems to be happening, and they don't relate to the bones found in the Afar region?

Then we find bones that belong to hominids that we had no clue that existed.

Years ago I read a book, “ The Washing Of The Spears”, about the Zulu, Bantu, in South Africa. It seemed that they arrived at the Orange about the same time as the Dutch.

The author stated that they had centuries to occupy a Continent but were to slow.

This peaked my interest and I did a lot of reading. The Pygmies where in Niger during Pharonic times, Herodotus, “The Histories”.

Another thing that caught my attention is that the Bushmen, the Hottentots, and the Adman Islanders, for example, seemed to have been pushed South West and West by pressure from the North East, I have no theory but it seems strange.

I don't know, Bwana... The straights of Gibraltar are really, really deep. My understanding is they are so deep Nazi subs could hug the bottom and slip thru to the Mediterranean even with the Royal Navy almost on top of them. According to Wikipedia they are from 980 to 2950 feet deep.

Still, I'll bet they could have used rafts.

The Australian Aboriginals were in Australia about 50,000 BC, and there was never a complete bridge. I think the closest land approach would still require a 26 mile water journey.

The Wallace Line explains it.

Walk up the eastern African coast to Suez, then down the Arabian coast. There have been points in history where the region probably had more rain than it has now, with good vegetation in what is currently desert.

The Red Sea being almost cut off like that jogs a memory — a hypothesis (antedates the “Noah’s Flood” thing of Ryan and Pitman) that there was an actual barrier during the lower ocean level, long-term, and the water wasn’t being replenished, the whole thing dried out, got rained on during the glaciation and the whole dried out basin became a warm, verdant paradise, which survived in myth as “Eden” and whatnot — and the Great Flood was actually when the earthen barrier gave away and/or the ocean level rose as the glaciers melted and ran off into the seas.

Yep. That's the problem with "science by media" which appeals to the egos of many current researchers. I think much of this "Out of Africa" stuff began with the Leakeys who hyped their work via National Geographic Magazine. NG, as we know, is as politically correct as it gets.

I look at the vast areas of Earth's surface that haven't yet been systematically investigated and common sense tells me we know only a little of the human origin story.
