Humans were once on verge of extinction, with less than 1,500 people left, reason will leave you shocked

The study is based on a computer model developed by a group of scientists from the USA, China and Italy.

People lived in all corners of the world today. But there was a period in which humanity was almost erased because of the world. According to a new study, it was when the global human population reached only 1,280 reproductive people. The study, published at Science Journal, is based on a computer model developed by a group of scientists from the USA, China and Italy.

How was the work carried out?
The findings of the study show that the human ancestors in Africa came before the existence of Homo Sapiens, also called modern people long before existing species. For the study, researchers received genetic information from more than 3,100 human genome using a statistical method. The analysis revealed that 98.7 percent of human ancestors disappeared. “This bottleneck is compatible with an important chronological gap in the existing African and Eurasian fossil record.”

What was the reason?
Although the exact cause of the sharp population fall is unknown, scientists say that Africa’s climate may be accused of decreasing. The continent witnessed excessive air, known as the transition of the middle-pleistocene, and became much more cool and more dry. The glacier periods have become longer and more intense, which led to a decrease in temperatures and very dry climatic conditions, which makes it more difficult to survive.

What do the researchers say?
Senior research writer Yi-Hsuan Pan said that the findings of work have opened a “new area in human evolution”.
“These individuals live in places where these individuals have experienced disaster climate changes and natural selection does not accelerate the evolution of the human brain during the bottleneck,” Yi-Hsuan Pan, an evolutionary and functional genomicist in East China Normal University in Shanghai. He said.
