Secret discovery of half a million years changed the history of humanity

The Great Rift Valley, the world's most enigmatic and mysterious valley, has just revealed to the way it motivates species to evolve and produce smart people.

The multinational archaeological team led by Richard Owen, a scientist from Hong Kong Baptist University, has deciphered the interesting secret related to the modern human source .

The periods of terrible droughts that lasted for hundreds of thousands of years in the "cradle of mankind" - the Great Rift Valley in East Africa - caused a mass extinction of many mammals but promoted hominins. (Human ancestors) evolved dramatically because of their instincts of survival.

Thanks to that evolution, about 315,000-320,000 years ago, a new species was born (wise people or modern people) , gradually hegemony the world and become the only race that exists. of Human species, due to its ability to adapt to outstanding living conditions and labor skills.

This secret was first revealed through the sediment that archaeologists collected at the lake of Magadi in the Great Rift Valley. The arid phase began 575,000 years ago, occurred in several phases, interspersed with easier time to live. However, there was an extension of more than a hundred thousand years, as it happened from 525,000 years to 400,000 years ago.

Another wave occurred after the 350,000 mark and was a direct hormone for the Middle Stone Age - when the wise man appeared. The artifacts of this period were determined to be 320,000 years old. Previously, the oldest man's bones were found in Morocco in 2017, dating to 315,000 years.

"Under the hypothesis of selective transformation, the rapidly changing environment creates natural selection pressures, making species change quickly. According to that scenario, the larger evolutionary brain will allow Our ancestors adapted to an increasingly unpredictable world " - Mr. Owen analyzed.

Not as fortunate as humans, many other ancient creatures became extinct during this difficult period.

The research has just been published in the scientific journal Proceedings of the National Academy of Science.

The Great Rift Valley is the largest rift valley in the world , spanning about 5,000 km and is estimated to be formed 35 million years ago, a large fissure on the surface of the earth. The valley is surrounded by many dangerous volcanoes, possessing green carpets interspersed with barren land and deep-bottomed lakes.
