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.Walk This Way What exactly does the fragment finger fossil of Al Wusta tell us?Well, well, well…you could say a new and highly significant fossil is really giving the finger to the human evolution and migration timeline once considered all but carved in stone.A discovery in the Arabian desert confirms Over the past few years, a number of separate research teams have been turning up evidence, including fossils, artifacts and genetic data, that have toppled the crusty old timeline for human evolution and dispersal beyond Africa.Direct dating of the finger bone suggests it is at least 85,000 years old, making it one of the oldest fossils ever found outside Africa.Authors of the study call AW-1, as it’s formally known, “the oldest directly dated fossil of our species outside Africa and the Levant,” and it’s an important distinction to make, since older fossils, controversially described by other researchers as , have been found in China.Petraglia, however, distanced today’s paper from that suggestion.

Yes, other teams have managed to extract genetic material from much older hominin fossils, such as those at Sima de los Huesos in Spain, which clocked in at 430,000 years old, but ancient DNA preservation requires both precise conditions — including cold — and a ton of luck.But, although previous digs had turned up stone tools pointing to a human presence there during this early Out of Africa period, a “smoking gun” human fossil had eluded researchers. The Dating Game In a study published in , researchers detail an intermediate phalanx, or finger bone, that was found at the Arabian desert site of Al Wusta.And yes, according to study co-author and University of Oxford archaeologist Huw Groucutt, addressing the media last week, “We think it’s the middle finger.” Sophomoric joking aside, what’s really important about the finger find is that its size and shape are consistent with rather than Neanderthals.Well, a lot, and not all of it fits into the new model of human migration.Let’s take another look at that new model of human dispersal proposed last December — one of its co-authors, Michael Petraglia, is also co-author of today’s AW-1 paper, and one of the leading voices in the recent push to focus on previously ignored areas, including Green Arabia, that may hold clues to a greater understanding of human dispersals out of Africa.
