▼ A prehistoric, broken skull is revealing the secrets of ancient humans, divulging that early modern humans left Africa much earlier than previously thought, a new study finds.
The skull, found in Eurasia and dating back 210,000 years, is the oldest modern human bone that anthropologists have discovered outside Africa, the researchers said.
This skull, however, had an unusual neighbor: a 170,000-year-old, possibly Neanderthal skull that was found resting next to it, in a cave in southern Greece. Given that the Neanderthal skull is a solid 40,000 years younger than the modern human skull, it appears that this particular human's early dispersal out of Africa failed. There are no living descendants of this enigmatic human alive today, and this person's group was replaced by Neanderthals, who later lived in that very same cave, the researchers said.
"We know from the genetic evidence that all humans that are alive today outside of Africa can trace their ancestry to the major dispersal out of Africa that happened between 70[,000] and 50,000 years before present," study lead researcher Katerina Harvati, a professor of paleoanthropology at the University of Tübingen in Germany, told reporters at a news conference.
Other earlier modern-human dispersals out of Africa have been documented at sites in Israel, including one based on the discovery of a 194,000- to 177,000-year-old modern human jaw from Misliya Cave and others tied to early human fossils dated to about 130,000 to 90,000 years ago at the Skhul and Qafzeh caves. But "we think that these early migrants did not actually contribute to modern humans living outside of Africa today, but rather died out and were probably locally replaced by Neanderthals," Harvati said. "We hypothesize this is a similar situation with the Apidima 1 [the newly dated modern human skull] population."

Discovery in Greece
The two ancient skulls were unearthed in the late 1970s by researchers at the Museum of Anthropology at the University of Athens. Given that the skulls were found in Apidima Cave, the researchers named them Apidima 1 and Apidima 2.
Both skulls, neither of which had a lower jaw, were found side by side in a block of breccia, angular pieces of rock that were cemented together over time. However, (▪ ▪ ▪)
