DNA SUPPORTS EARLY EVOLUTION OF HOMO SAPIENS

A new study has been discovered which breaks apart all the notions. It is suggests the timeline of homo sapiens. The paper was made public in Science on 28th September, where the researchers concluded that the homo sapiens has first existed almost 2,60,000 to 3,50,000 years prior. The new fossil found in Morocco dates back to 3,00,000 years ago. This pushes the timeline of homo sapiens a further back.

THE STUDY

So far, the earliest known fossils of homo sapiens from Ethiopia were lesser than 200000 years old but in June, a fossil had been discovered in Morocco which suggested the species of humans to have originated around 300000 years ago.

 

The skeleton of a young boy who had lived 2000 years ago in South Africa was taken and compared with the DNA from the Stone Age Neanderthals and Denisovans. As per the reports in Science, the West African humans had migrated 2000 years ago to Eat Africa but the new findings seem to have reshaped the entire genetic pattern.

 

Since the DNA of the young boy showed no hints of any migration, the question arises on when humans originated in Africa. The discovery of a 300000-year-old fossil further cements the pushing back of the date. It is still a hazy matter concerning the emergence of homo sapiens.

 

The mixing and mating of different cultures had a genetic impact on the human population. Stone Age humans are said to have mated along their way to Africa’s regions. There has been evidence of shared ancestry between the DNAs of 16 Africans ranging from 8100 to 400 years ago.

 

The researchers have even observed that the genetic diversity between Khoisan and other Africans had taken place more than 260000 years ago which made the Khoisan people diversify into two types of populations with the genetic split between them. The scientists even compared DNAs of ancient humans with modern humans to understand when the split occurred.

 

The study was conducted to understand the population split and time period when it all occurred. The scientists are gauging the time period to understand the actual origin of our species. The splits pay a vital role in understanding the origin of human species.

THE END STORY

The study provides an insight into the timeline of the origin of homo sapiens. Unlike the previously known timeline of homo sapiens being 2,00,000 years old, the latest discovered fossil has pushed the date back to further.
