The world's oldest Homo sapiens (currently living human beings) of 315,000 years ago was discovered in Morocco, and as a result that the established theory overturned

Until now, the idea that "the oldest present-day human beings originated from East Africa 200 thousand years ago" was an established theory, but a fossil of the skull that reversed it was discovered in Morocco. The discovery of this time showed that the oldest present-day human beings were present not only in East Africa but elsewhere on the African continent about 315,000 years ago.

Oldest Fossils of Homo Sapiens Found in Morocco, Altering History of Our Species - The New York Times

The fossils newly discovered this time are Paleoanologists belonging to the Max Planck Evolutionary Anthropological Research Institute in Germany. This discoveryIt was announced at Nature dated June 7, 2017.

The oldest fossils confirmed so far are skulls from 154,000 to 160,000 years ago discovered by researchers working in Herto in Ethiopia in 2003, as well as the Omo- It was a part of the skull that was discovered in the place called Kibish 195,000 years ago. Because of the discovery of fossils in close proximity to Ethiopia, the idea that the oldest present-day human beings evolved in relatively narrow areas and then spread to various parts of the African continent, then moved to another continent It was an theory.

On the other hand, skulls and stone tools were found in Morocco in the place called Jebel Irhoud from around 1961, but at the time those fossils were presumed to be from the Neanderthal people around 40,000 years ago. However, in the 1980's, an anthropologist Jean-Jacques Hublin began a survey focusing on the jawbone of fossils. Although the form of the discovered teeth resembled the present mankind, I realize that it has a very primitive shape. As a result of further investigation, in 2004 discovered skulls from Jebel Irhoud strata and stone tools that are considered contemporary with skulls. As these stonewares had evidence of the use of fire, Hublin et alDating by thermoluminescenceAs a result of multiple measurements, etc., it was concluded that the stoneware was about 300,000 years ago. In other words, the skull that was discovered as a stone tool and the same period is also 300,000 years ago.

The living human beings discovered at Jebel Irhoud in Morocco have larger eyebrows, smaller jaws, flat and wider faces than modern human beings, but as a whole they are similar to the present human beings . "You look like you pass by the subway," Hublin says. On the other hand, the shape of the brain is very different from the current human beings, and it was an elongated shape like the early human family.

Fossils similar to fossils, which were deemed to be 315,000 years ago in this study, have been found in various parts of the continent of Africa, and researchers believe that the current human beings form a network throughout Africa We are discussing the possibility that it was doing.
