The amazing discovery of human ancestors inflates the theory in practice

According to the study, its results were published in the processes of the National Academy of Sciences. Time with their relatives in East Africa. Africa.

After scientists estimated the age of a skull known as “Mrs. Plus”, one scientist said it was the most complete Australopithecus skull found in South Africa in 1947 between 2.1 and 2.6 million years ago. Geography French, Laurent Brussels, that is not true.

Scientists have compared the age of “Miss Plus” with the skeleton of the “Little Food Astrolopithecus” 3.67 million years old, based on the analysis of sediments near the site of her discovery.

The researchers used a technique called “cosmic nuclide dating,” which looked at the levels Isotopes It is rare to form when there are rocks Quartz For high speed particles.

According to Daryl Granger of the University of Purdue in the United States, the lead author of the study, Radiation analysis According to “Ms. Plus” and fossils found near her, she is between 3.4 and 3.7 million years old.

Granger explained that the South African “Australopithecus” was previously thought to be the smallest ancestor of the “Australopithecus” species.Homo‘, I.e. Lucy’s homeland in East Africa was believed to be the most viable location For the evolution of the human raceBut new research shows that it took South Africa almost a million years to become the ancestor of the Australopithecus Homo sapiens.

He added: “Our family tree is really like a bush. In millions of years, just 4,000 kilometers apart, these species had plenty of time to travel and reproduce with each other, so we can imagine a parallel. -Evolution across Africa.” , According to the British newspaper, The Guardian.
