Some articles reporting these new datings of Iberian Neandertals placing them 10,000 years earlier then they were previously are also insisting then there is no way modern humans interacted with Neandertals as modern humans were not in the same place at the same time. (That Nature article isn’t one of them, but this EurekAlert does.) That’s nice, but the genetics studies already show Neandertals and humans did interact, perhaps not in Iberia, but somewhere. I reckon that it’s just science journalists who haven’t accepted the genetics proofs are just ahead of the curve of the fossil evidence.
There’s another study arguing earlier dates for modern humans out of Africa than 60,000 years ago, in multiple dispersals. (via Dienekes.) Even if Neandertals all went extinct earlier than thought, not just the ones in the Iberian peninsula, they still had the opportunity to interact with modern humans, as they were already in Europe.
When the agricultural revolution swept into Europe, the area around the western Mediterranean was a lot more humid than it is today. The chemistry of snail shells from Mediterranean caves dating from 2,500 to 9,000 years ago are proving this.
Aha. A confession…. Because I’m just winging this, learning this much of mateiral through independent research, I wasn’t precisely clear on the development of the bow & arrow, and how the technology dispersed. Apparently it came about 64,000 years ago in South Africa. Apparently this date and place was nailed down when I was slacking back in 2008. A new paper walks through the steps that led to the bow & arrow.
So why are people like Paul Mellars of Cambridge still arguing that humans left Africa only after Toba explosion 60,000 years ago? In this Nature article, he states humans followed the coastlines rapidly with their new technologies, including bow and arrows, all of the way to Australia. As far as I’m aware of, the Australian aborigines didn’t even have the bow and arrow. That technology wouldn’t have been arbitrarily dropped at the Wallace Line. It seems obvious that there were human waves of dispersal both before and after Toba.
However, the other side of the argument in that Nature article is Petraglia, whose argument seems stronger to me until he states, “no one has ever argued for Neanderthals in India, ever,” in arguing that whatever artifacts he finds in Jurreru Valley must be made by modern humans.
Okay. How about Denisovans? Or another archaic human? The funny thing is towards the end of the article, which feels a little exciting. Petraglia has sympathizers who are proposing just that.
The pre-Toba artefacts from the Jurreru Valley look nothing like the Arabian ones, says Anthony Marks of Southern Methodist University in Dallas, Texas, who studied the Jebel Faya material. And the archaeologist who analysed the oldest relics from the Jurreru Valley and provided key support for the claim that they are the handiwork of modern humans is no longer so sure. Chris Clarkson of the University of Queensland in Brisbane, Australia, a frequent collaborator of Petraglia’s, now thinks they might be the work of an unidentified population of archaic people.
This is definitely something to be followed.
yeah, yeah…. old news, but it’s nice to see this is turning more mainstream view. Stone tools dated to 127,000 years ago in United Arab Emirates and 75,000 years ago in central India are the bits used as leverage against the old modern humans exited Africa 50,000 years ago theory… which doesn’t seem that popular anymore.
It’s Clovis all over. It’ll be a theory that gets toppled over and over for the next decade.
67,000 year old human fossil is found in cave in Philippines. It’s suspected that it’s an earlier species than Homo sapiens, but they are still looking for more bone fragments. That could just be some nationalist/nativist posturing though.
A new radioactive dating method places Peking Man at 200,000 years older than previously thought, moving its period from 500,000 years ago to 780,000 years ago. I wonder how this is going to shift the map of the dispersal of Homo erectus.
Also, remember how on Flores, the same team that discovered Homo floresiensis, also claimed to find evidence of Homo erectus there dating to 840,000 years ago? It’s probably irrelevant, but…
Tim at Remote Central notes an article from an Iranian news agency that states rather blandly that artifacts “very similar to those found in East Africa” are being excavated by Iranian teams from caves near Damavand.
Know what would make that cooler? If fossils turned up looking like Homo georgicus.
