Petraglia, however, distanced today’s paper from that suggestion.He notes that, even with lower sea levels during various periods of the Late Pleistocene, the crossing at Bab el Mandeb would have required watercraft of some kind.

A deformity visible on one side appears to be an abnormal bony growth called an enthesophyte, which typically results from trauma or repeated stress to the bone at the location.The bone also appears to show signs of intense manual activity.Today’s fossil find comes from Al Wusta, however, deep in the interior and hundreds of kilometers across the Arabian desert from either of the hypothesized routes.Regardless of how humans arrived in Green Arabia, they would have found a veritable land of plenty.Based on paleoclimate research, the area around Al Wusta, in the interior of the Arabian Peninsula, would have been semi-arid grassland populated by mainly African animals — more than 800 vertebrate fossils were found in the vicinity.

The site included a freshwater lake that would have been a few meters deep year-round.Projects such as Palaeodeserts have allowed researchers to recreate the Arabian Peninsula’s past climate and determine that it was once a far more hospitable place, precisely the sort of environment that would attract our species.Satellite imagery and other methods, for example, have revealed that Arabia was once home to 10,000 lakes, some filled by monsoonal rains and only seasonal, but many others existing year-round.At the end of 2017, based on the piles of new evidence that have emerged from multiple disciplines, paleoanthropologists called for a new model of the human story to be embraced by the field (though, as with any scientific advance, holdouts remain).The revised timeline goes something like this: Humans emerged as a species more than 300,000 years ago (and probably even earlier) and began leaving Africa to explore Eurasia, starting with the Levant and sites such as Skhul and Qafzeh, at least 120,000 years ago.The process of extraction is also destructive to the fossil itself, so the team isn’t going to go grinding up the precious find knowing it almost certainly won’t yield any DNA.
