    Modern humans left Africa many earlier researchers identified the remains of the oldest known modern humans who left Africa

    A new history of excavations from Israel indicates that our species (human sage) lived outside Africa about 185,000 years ago, about 80,000 years ago.

    Details appear in the journal Science.

    The study's co-author, Prof. Israel Hershkovitz, told BBC News that the discovery would radically change the ideas of recent human evolution.

    "We have to rewrite the whole story of human evolution, not only to our species but to all the other species that lived outside Africa at the time," says the researcher from Tel Aviv University.

    "The research finds an age-old limit of 130,000 years for modern humans outside Africa," said Professor Chris Stringer of the Natural History Museum in London, who did not participate in the study.

    "New dating suggests that there can be even older human sage finds to come from the West Asia region."

    New evidence dating from anthropology raises the possibility that modern humans can interact with other species that have now become extinct for tens of thousands of years. It is also consistent with the recent discoveries of genetic remains and studies that also point to the earlier departure from Africa.

    Researchers analyzed part of the jawbone with eight teeth, found in the cave of Meselia in 2002. The jawbone looked as if it were a modern human rather than one of the other species of humans that existed at the time.

    Not only that the international research team has shown conclusively that the initial gut feelings archaeologists were immediate.

    The researchers confirmed that the jaw belongs to the modern human by conducting a CT (CT) of it, building a virtual 3D model and comparing it with the ancient human fossils of Africa, Europe, and Asia - as well as modern human remains. Separate tests also enabled researchers to investigate tissues under the crowns of teeth, which were found to be uniquely associated with modern humans.

    Three separate methods of acquaintance, conducted in three separate laboratories unaware of the results of others, concluded that fossilized remains were between 177,000 and 194,000 years old.

    Prior to this, the oldest evidence of humans outside Africa from the sites of Saul and the archaeological jump in Israel, dating back to between 90,000 and 125,000 years ago.

    The remains of Meselia were found in a layer containing limestone vessels belonging to the Levallois type, which was used in the area between 250,000 and 140,000 years ago. If Levalua's tools are related to the spread of modern humans in the region, they suggest that our species may have traveled beyond Africa even before the Meselia materials.

    Until recently, the early evidence of trips outside Africa by the wise man was limited to the Levant. But in the past few years, recent discoveries of human fossils from Daoxian and Zirendong in China indicate that between 80,000 and 120,000 years ago, the first waves of migration have pushed Eurasia more than previously thought.

    In addition, genetic studies have turned into early signs of mating between African human beings and our evolutionary relatives Neanderthal.

    Last year, researchers published evidence of the German Neanderthal remnants of mixing that occurred between 219,000 and 460,000 years ago. In 2016, a team found signs that leading groups of Africa had overlapped with Neanderthal in the Altai region of Siberia some 100,000 years ago.

    "We had a lot of new evidence, and we did not know where it was installed," Professor Hershkovitz said.

    "Now with the new discovery, all the pieces are in place - possibly as early as 250,000 years ago, the history of the tools found in the cave of Myslaya."

    However, the first trips in Eurasia by the African-wise man represented in Meselia are generally thought to have ended in extinction. The results of genetics and archeology suggest that people currently living outside Africa trace their origins to migration only 60,000 years ago. Most DNA studies have failed to find evidence of these ancient migrations in our genes.

    Other discoveries have revealed how humans evolved in Africa to become anatomically modern. Last year, a team announced that fossils believed to be early versions of human sage in Morocco may have been about 315,000 years ago.

    This is long before the 200,000 years of generally accepted history of the origin of our species, which is based on genetic studies and fossil finds such as the 195,000-year-old Omo still from Ethiopia. Future discoveries are likely to push history even further.
