7,000-year-old mummy discovers not sharing DNA with modern humans

The Sahara Desert is a region where people do not exist, not to mention it flourishes today. But the Sahara desert looked very different thousands of years ago, when groups lived in the region and eventually merged with each other. But a group of people have been genetically isolated for thousands of years, as two 7,000-year-old mummies that do not share DNA with modern humans have recently been discovered.

One published in nature Revealed that a group called takarkori might have moved to the Sahara thousands of years ago. It is worth noting that unlike other people living in the area, Takarkori managed to maintain 50,000 years of genetic isolation.

In the tissues that discovered two mummies near the Takakori Rock, genetics was found in tissues containing extractable DNA, which is a rare discovery in itself. DNA sequencing shows that Takarkori does not share DNA with modern culture. So, this means that when the organization becomes uninhabitable and is forced to move out of the Sahara, the organization disappears, or their DNA becomes so diluted that only a small percentage can match those who live in North Africa.

The actual lineage of Takarkori remains a mystery. Takarkori is known to share the closest genetics with Taforalt in Morocco. But there are differences there too. According to the study, Taforalt’s “half of Neanderthal mixture” has a much higher Neanderthal gene than Tarkarkori, which has ten times less Neanderthal genes.

Takarkori has “significantly more” Neanderthal genes than the modern sub-Saharan genome. This means that despite possible contact with other groups during the humid African period of the Sahara, Takakori chose to keep himself alive, never genetically mixed for tens of thousands of years.

The Sahara is not always a desert

Today, the Sahara Desert is regarded as a hot sandy area, and even the most sturdy animals are difficult to survive. But, thousands of years ago, it was nothing more than a drought area like today. Instead, it is lush and supports herders and even agriculture.

Given that the Sahara Desert environment was in the opposite direction of today’s environment 6,000 to 4,000 years ago, the period when it thrived with today’s lakes, grasslands and savannas was called Wet times in Africa. During this period, the Sahara Desert was also known as the Green Oasis.

While conditions in this area were known in the past from more changes to less drought, things began to change when pastoralists came to the area. According to David Wright, lead author of a 2017 study, the author of David Wright, Earth Science Field,,,,, Overgrazing goats and cattle may change the landscape forever West Africa.

“By overgrazing grass, they are reducing the amount of atmospheric moisture (the plants emit the moisture that produces clouds) and enhancing the albedo.” – David Wright

Essentially, by having so many animals eat the grassland together with the spinning sheep and cattle, there is no longer enough moisture in the air to keep the ecosystem prosperous. As the area becomes drier, it is impossible to reverse the process as vegetation has disappeared in the past.

So sand started to replace what was once green, and the only residue of the remaining time today is the underground aquifers that support the oasis in the desert Due to climate change, seasonal lakes occur more frequently and last longer This form in the monsoon season.

Due to the different environments in the Sahara

When the Sahara desert flourishes with mountains, wetlands, forests, etc., people can live in many environments without having to contact each other unless they want.

believe Takarkori does come into contact with others in farming, trading, etc.According to Savino Di Lernia, another author of the study. This is how to learn about herders among all the groups living in the Sahara Desert.

“We now know that they are genetically isolated, but not culturally isolated. From several parts of the continent, we know a lot of networks because we have pottery from sub-Saharan Africa. We have pottery from the Nile Valley, etc.” – Savino di Lernia

“They have this lineage, which is ancestral, and (this) points to some kind of Pleistocene legacy that needs to be explored,” Di Lernia explained.

There was never any confusion in the Sahara desert with other crowds. In short, it makes it more meaningful to stay as different environments make it difficult to travel where a group of people live. This means that genetics remains the purity of Takarkori until the Sahara no longer exists after the Sahara resides.

This means, unlike the assumptions previously claimed Green Sahara is the gateway for the community to come togetherwhich is more like a “block” than anything else.

After the Sahara desert was uninhabitable in human life, Takakori seemed to no longer exist. Despite the genetic similarities of modern North African people, more people need to be discovered to determine when Takakori went from a genetically distinct population to a population that eventually confused with the rest of Africa.

Takarkori is not a nomad, but is longer in one area than most other groups. This also prevents the group from mixing genes with others. As a result, Takarkori retained more Neanderthal DNA than other groups that lived in the Sahara at the time.
