Modern fossil discovery rewrites human history

Modern fossil discovery rewrites human history”

That timeline was completely upended by recent fossil discoveries in Morocco that revealed the origin of our species actually dates as far back as 350,000 years.

"This finding changes our view on modern human dispersal and is consistent with recent genetic studies, which have posited the possibility of an earlier dispersal of Homo sapiens around 220,000 years ago, "the researchers say in the paper's abstract.

It was one of these terraces where they could overlook the landscape in front of them", says study co-author Rainer Grün, director of the Australian Research Centre for Human Evolution at Griffith University in Queensland".

On Thursday archeologists announced the finding of a fossilized human jawbone in a collapsed cave off the Northern Coast of Israel that is threatening to rewrite the lineage and narrative of human migration out of Africa. The work puts our ancestors' initial trek out of Africa even earlier in human history, pushing it back by more than 40,000 years, according to an global team of researchers. "We were not expecting to find a modern human so early in time". Israel Hershkovitz of Tel Aviv University's Anatomy and Anthropology Department.

The fossil could indicate that Israel and the rest of the Arabian Peninsula were part of a larger region in which H. sapiens evolved, says John Shea, an archaeologist at Stony Brook University in NY.

"There isn't very good evidence for these early humans being part of our gene pool outside of Africa", says Petraglia.

For early humans, the Levant was the gateway to everything beyond Africa.

The discovery, details of which were published in the journal Science, suggests there were multiple waves of migration across Europe and Asia, and could also mean that modern humans in the Middle East were mingling, and possibly mating, with other human species for tens of thousands of years. The revelation means early Homo sapiens left Africa at least 120,000 years earlier than we had previously thought.

It is a hefty contribution to the study of how humans populated the earth, because the previous weight of scientific evidence suggested that humans only began leaving Africa around 100,000 years ago.

And the latest genetic work hints that there may have been even earlier treks out of Africa-and into the midst of other human species, adds Hublin.

They made their stone tools using a technique called Levallois, which originated in Africa at least some 300,000 years ago and is known to have been used by both humans and Neanderthals.

The team has applied several dating techniques that places the jawbone between 175,000-200,000 ago, pushing back the applied date for human migration from Africa by at least 50,000 years.

Archaeologists discovered the jawbone at the Misliya cave site in Israel. Shea notes that from the standpoint of climate and environment, Israel and its neighbors were, in essence, a part of Africa, harboring mostly the same kinds of animals. It belongs to a homo sapiens species.

Recent developments in philosophy & material advancements in technology have provided a consensus that places Homo Sapiens first known whereabouts in Northwestern Africa nearly 300,000 years ago.

The entrance to Misliya Cave, one of several caves located on the west side of Mt. Carmel that hold evidence of prehistoric human activity.

The remains are unquestionably H. sapiens, says team member María Martinón-Torres, a palaeoanthropologist at the National Research Centre on Human Evolution in Burgos, Spain.
