New path for early human migrations through a once-lush Arabia contradicts a single 'out of Africa' origin

...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.

How many times over that period was the Red Sea either mud or sand? I’d say more than a few.

Since these dates are “between 125,000 and 43,000 years ago”, just once or twice.

[snip] There were at least 17 cycles between glacial and interglacial periods. The glacial periods lasted longer than the interglacial periods. The last glacial period began about 100,000 years ago and lasted until 25,000 years ago. Today we are in a warm interglacial period. [/snip]
