Africa was once home to many different types of people, says new study | Science | news



Until recently, the common belief was that Homo sapiens originated in the East African Rift Valley 200,000 years ago, before leaving the continent and populating the rest of the world 60,000 years ago.

Recent discoveries, however, presented a challenge This simplistic view shows not least that our ancient ancestors mingled with Neanderthals and the mysterious Denisovan hominids at different times.

A study conducted by a team of German and British experts led by Drs. Eleanor Scerri has been carried out, already pointing to Africa The situation was much more complicated than previously thought.

Their report, published on the scientific website cell.com, said: "We question the belief that our species Homo sapiens has evolved within a single population and / or region of Africa."

The in Diversity detected in Pleistocene human fossils indicates "morphologically distinct" populations that, according to the study, lived throughout Africa.

It ad ded: "Genetic studies also suggest that today's population structure in Africa extends into deep times, parallel to a paleoenvironmental record of shifting and fractured habitable zones."

"We argue that these fields support an emerging view of a highly structured African primal history that should be considered in human evolutionary inferences and generate new interpretations, questions, and interdisciplinary research directions. "

Early Human Fossils Dateed to 500,000 Years" It has not shown a simple linear evolution, as we have said in the study.

She stated, "Along with the recent archaic archaeological and genetic lines of evidence, these data are strongly in line with the view that our species originated and diversified within and outside their species revealed populations, probably across Africa, that were linked by sporadic gene flow. "

The concept of" African multiregionalism "could also include the hybridization between Homp Sapiens and divergent hominins in different regions.1

9659002] It said," The next decade of research will be crucial to solving these emerging resolutions on Earch themes , Human present genomes are now available across the African continent along with an increasing number of ancient genomes.

"The expansion of paleoanthropological studies into neglected areas of Africa will undoubtedly reveal new data that will significantly refine the parameters of recent human evolution."

Darren Curnoe, an Associate Professor at the University of New South Wales who specializes in evolutionary biology.

He said, "A few years ago, it all seemed too easy, the matter was settled."

"Homo sapiens had developed in the East African Rift Valley about 200,000 years ago and left the mother continent to about 60,000 years ago to colonize the remaining planet.

"As someone who has been closely monitoring the developments in and indeed actively researching our evolution, I realize that something is going on here, change is in the wind!"
