Ancient human lineage thrived in Sahara’s once lush landscape

The Song Single is one of the drought and most barren regions of the earth, which is spread in most North Africa. It covers parts of 11 countries and covers the size of China or the United States. But it has not always been so unhealthy.

During the period of about 14,500 to 5000 years ago, it was a lush green sauce that was rich in water bodies and was found with life. And, according to the DNA obtained from the remains of two people, who were now living almost 7000 years ago, it had a mysterious lineage of people isolated from the outside world.

Researchers analyzed the first genome of people called “Green Sahara”. They obtained DNA from the bones of two women buried in a rocky shelter called Takrori in southwestern Libya, remote. He was naturally gambling, representing the oldest well -known forbidden human remains.

“At that time, Takorkori was a lush savan, unlike the scenes of today’s barren desert,” said Johannes Craws, an archaeologist at the Max Planck Institute for Evolution, a study published this week in a journal published in the journal.

Genomes have revealed that the Takori people were part of a separate and first unknown human lineage who, for thousands of years, had been separated from the Sahara and the Eurasian population.

“Amazingly, the people of Takkuri do not show any particular genetic influence from the sub -sacred populations in the south or near the east and the north, in the eastern and north, to the sub -sacred populations. This shows that they remain genetically isolated despite practicing animals.”

Archaeological evidence suggests that these people were pastoralists, raising rare animals. The site found on the site includes stones, wood and animal bones, kerosene, woven baskets and tools made of sculptures.

The lineage of the two people was found to be derived from the North African lineage 50,000 years ago, which was separated from the sub -salaw population. At the same time, it is compatible with when other human beings spread out of the continent and in the Middle East, Europe and Asia – become the ancestors of all people outside Africa.

“The takori lineage represents the remains of genetic diversity in North Africa, potentially 50,000 to 20,000 years ago in North Africa,” Craws said.

“20,000 years ago, genetic evidence reveals the arrival of groups of the East Mediterranean, followed by 8,000 years ago from Iberia and Sicily. However, for unknown reasons, the active lineage was longer than expected, because it was only 15,000 years ago.

Before Sahara became uninhabited again, his lineage was isolated in most of his existence. At the end of a hot and wet climate phase called the African humid period, the Sahara converted to about 3,000 BC into the world’s largest desert.

Members of our species Homo Sipins, who spread from Africa, encountered them and interfered with the already existing nendathetic populations in some parts of Eurasia, which today left the genetic legacy of non -African populations. But the green supporters only detected the amount of Nandarthal DNA, which made it clear that they had little contact with the external population.

Although the African humid period ends and returns to the desert, the population of Takarkori has disappeared 5000 years ago, but today their lineage marks are among the North African groups.

“His genetic heritage offers a new approach to the deep history of the region,” said Craws.
