New path for early human migrations through a once-lush Arabia contradicts a single 'out of Africa' origin
The Conversation ^ | October 4, 2023 | Michael Petraglia, Mahmoud Abbas, Zhongping Lai

...we find the now inhospitable and hyper-arid zone of the southern Jordan Rift Valley was frequently lush and well-watered in the past.

Our evidence suggests this valley had a riverine and wetland zone that would have provided ideal passage... out of Africa and deep into the Levant and Arabia...

Our findings from sedimentary sections ranging 5 to 12 metres in thickness showed ecosystem fluctuations over time, including cycles of dry and humid environments. We also found evidence for the presence of ancient rivers and wetlands.

Luminescence dating showed the sedimentary environments formed between 125,000 and 43,000 years ago, suggesting there had been multiple wet intervals...

Further evidence for a northward expansion comes from the famous Skhul and Qafzeh cave sites in Israel. Fossils of Homo sapiens and Levallois stone tools have been found here.

Towards the south, fieldwork in northern Saudi Arabia has also demonstrated a network of rivers and lakes was once present in the region. This allowed humans to penetrate a green Nefud Desert replete with savannahs and grassland...

Our findings from the Jordan Rift Valley indicate there were multiple early human migrations from Africa, and into Asia, during favourable conditions. This opposes the theory of a single, rapid wave of human movement out of Africa 60,000 years ago.

Our results also suggest, together with the Levantine and Arabian evidence, that hunter-gatherers used inland river and wetland systems as they crossed South-West Asia. This contradicts a popular model suggesting they mainly used coastal routes as super-highways.

Although ancient DNA evidence indicates Homo sapiens interbred with Neanderthals and Denisovans multiple times as they spread into Asia, on-the-ground evidence for these encounters has generally been lacking. Our findings provide further evidence this area served as the ground for these encounters.

So there goes my chance to say I am an “African-American” and collect reparations.

Sounds like the climate changed or something.

“Sounds like the climate changed or something.”

I know you are being sarcastic, but you are right about the “something”.

The earth’s axis tilted causing the equator to shift locations.

I'm becoming really tired of the term, "hunter gatherer," being certain that things were more complicated than that. If ants can manage which seeds they bring to the surface and plant, so aboriginal humans capable of making stone tools would be entirely capable of manipulating vegetation and animals to some significant degree. Caves would certainly be attractive for multigenerational habitation. One would think people would learn to manipulate plants for tools or food thereabout. Etc. Hell, I have found proto-agricultural plots on our land, and identified their likely purpose of arrangement just from making it possible for the seed to express.

IOW anthropology, botany, and archaeology need to work together on an experimental basis more than I have seen. The process might develop new means of identifying pre-historic land use patterns.

I agree, it’s a false division, or maybe more accurately an archaic and outdated one. Hunting and gathering is just part of being opportunistic feeders, and “Opportunistic Feeder” would be a great brand name for my next refrigerator. Toolmaking probably went from being for hunting or processing to being for self-defense really rapidly, and agriculture / gardening is probably so old we’ll never find out just how old it is.

The science is settled...

So come on baby, let’s start today, come on baby, let’s play

You might appreciate the site history chapter of our project as it contains a repeating excercise in making such inferences.

Sory, don’t know how that one happened.

Thanks! I’ve been having a lot of copy/paste problems. Could be the old computers I use, could be some CCP hack, or other gubmint police state surveillance.
