A Skull Bone Discovered in Greece May Alter the Story of Human Prehistory https://www.nytimes.com/2019/07/10/science/skull-neanderthal-human-europe-greece...

Cool finding. And consistent with the emerging body of data that at least small groups left Africa much earlier. These are thought not to have “taken”, as there’s no doubt of the source of all non sub Saharan Africans being from the dispersal 70,000 years ago. Except a small few who argue for an earlier date for some Australasians, but that’s not genetically supported.
As Chris Stringer, renowned paleoanthopologist whose name is on the above paper says:
“'If these latest analyses are correct, H. sapiens entered Europe over 150,000 years earlier than we thought, raising a whole new range of questions and possibilities including where they came from and what happened to them,' explains Chris.
'The most likely route from Africa would have been through the Near East, and the existence of such early sapiens groups outside Africa has already been suspected from enigmatic signs of early DNA exchanges between Neanderthal and H. sapiens populations.'
The dating suggests that there may be further evidence for these modern human populations in Europe and the surrounding regions, and it could be just that researchers have not been looking for them.
'Unfortunately, there are no stone tools directly associated with either of the Apidima crania to help in establishing connections elsewhere,' says Chris. 'But if we have interpreted the Apidima evidence correctly then the handiwork of these early H. sapiens must be present elsewhere in the European record.'”
He could have gone on to add that it is not just DNA exchanges that constitute the evidence for earlier waves of ultimately unsuccessful dispersal, but also fossil finds in Arabia and the Levant over the last several years.

>2 stellarexplorer: Thanks for the extra info. "Unsuccessful dispersal" is such a nice term for what happened to these early waves.
