And the scientific website “Life Sins” said, on Wednesday, that this study sheds light for the first time on how humans have expanded around the world.
The study was published in the scientific journal Nature Communications on Tuesday.
The study stated that the Arabian Peninsula, which currently includes Saudi Arabia, the UAE, Oman, Qatar, Bahrain and Kuwait, has always been a major crossroads between Africa, Europe and Asia.
The results of the study, which examined archaeology, fossils and DNA, show that the Middle East and its peoples can reveal more about the exodus of modern humans from Africa towards the rest of the world.
The Arab fairies have not been adequately studied, as the scientific website says, which explains the new findings of the study.
In the new study, the researchers examined the DNA of 6,218 adults in the region, and compared it with results from others in other regions of the world, as well as the DNA of ancient humans who lived in Africa, Asia and Europe.
This is the first large-scale study on the Arab population, said the study’s lead author, Yunus Mokarrab.
The scientists participating in the study concluded that the human groups that inhabited the Arabian Peninsula made a significant genetic contribution to the societies of Europe, South Asia and even South America.
This is due to the emergence of Islam and its spread around the world more than 1,400 years ago, and people from there intermarried with people from different regions around the world.
Muqreb said that the Arabian Peninsula was the cornerstone of the early migrations out of Africa
He added that he viewed the Arab population as descending from the Europeans.
After modern humans left Africa, they interbred with some extinct human lineages, such as Neanderthals and Denisovans, whose ancestors left Africa long before and traces of them have been found in Asia and Africa.
Muqreb explained, “The timelines that were discovered in our study on the Arabs explain why the DNA of Neanderthals is rarer in the Arab population than in the population groups that later mixed with the ancient hominins.”
Moreover, after comparing the modern human genome with the ancient, scientists discovered that a unique group of Arabs in the peninsula may be the oldest among all the groups of the modern Middle East.
The researchers said that members of this group may be the closest relatives of the early farmers, hunters and gatherers known who occupied the ancient Middle East.
They pointed to divisions in Arab populations between 12,000 and 20,000 years ago, and researchers said this coincides with the way the Arabian Peninsula became drier, with some groups moving to more fertile areas.
