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] “

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.
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.
