Fossil found in Israel suggests Homo sapiens left Africa 180000 years ago

Collectively, the results indicate the fossil is somewhere between 177,000 and 194,000 years old. DNA analysis of remains from mysterious people known as the Denisovans suggests an ancient world that looked like Tolkein's Middle Earth - except instead of hobbits, elves and dwarves wandering around, our planet had many species of interacting, interbreeding hominins. If humans had barely begun to exit Africa 60,000 years ago, how can we explain these other findings? These early evolutionary ancestors are recognized as belonging to the human family mainly because their bones reveal clear signs of bipedalism: They walked on two feet. Once there, humans probably encountered and interbred with Neanderthals, Hershkowitz says, pointing to a 2017 ancient-DNA study that suggested interbreeding had occurred before 200,000 years ago. An global team of researchers dated the fossil to between 175,000 to 200,000 years ago.

That date was based on fossils found in Skhul and Qafzeh caves in Israel, which were dated to between 90,000 and 120,000 years ago.

Weinstein-Evron has worked at the Misliya site for almost two decades, uncovering scores of discarded tools, animal bones, even evidence of fire - discoveries that span the 100,000 years in which the cave was in use. He and his colleagues have previously said that 175,000-year-old stone tools from other sites in the Middle East resemble those used by H. sapiens in East Africa.

An worldwide team that includes Tel Aviv University, Binghamton University and the University of NY has announced the discovery of the earliest modern human fossil to be found outside of Africa dating from 50,000 years ago.

Most past efforts to confidently pinpoint a time our more immediate ancestors have primarily come down to using art and artefacts, which had left us with a rather recent departure date of just over 40,000 years ago.

While geneticists have traced the modern human's emergence from Africa back around 60,000 to 80,000 years, "skeletal information excavated by archaeologists has told a much older story", Professor Hiscock said.

An intriguing sidenote about the Levallois method is that the artifacts it produced, found in Europe as well as Asia and Africa, tend to be more uniform from one to the next than those of earlier technologies.

After establishing the jaw-owner's species, it was time to find out how old it was. In 2015, he announced finding a 55,000-year-old skull in the Levant.

The cave had been occupied for several hundred thousand years, she says. But scientists say that it is unclear whether the fossils represent a brief incursion or a more-lasting expansion of the species. We micro-CT scanned and made 3-D virtual models of the specimen to visualize the internal structures of the teeth and quantify their shapes more precisely.

But the Misliya fossil also has researchers theorizing that modern humanity evolved alongside - intermingling with - other hominin groups, such as Neanderthals, Hershkovitz told the Times.

The dating seems solid and the fossils are H. sapiens, says Huw Groucutt, an archaeologist at the University of Oxford, UK. The latter method was also employed on nine burnt flints near the fossil.

Our study found these teeth lack several features that are found in earlier human species, including the Neanderthals. Anthropologists call this trait shoveling.

"It implies that our species didn't evolve in isolation". Now we see how right we were to give it such a promising title...

But the new discovery provides further evidence to support the theory that Homo sapiens first trekked out of Africa through a northern route along the Nile river and not through a mid-continental route across the Bab al-Mandeb strait into the southern coast of Saudi Arabia, India and then Asia.
