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 modelsTo 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.

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 6030 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] “

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.
AKA who pays the piper calls the tune.
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.
26 miles across the sea?

Would you mind expanding on your catty remark. I don't know what to make of it except you may be trying to cut off debate on the subject, but I'm speculating. As one who has appeared to be generally skeptical of much of what the Scientific Community spews, you make short shrift of a skeptical comment from another Freeper. What's up with that???
