Humans are almost extinct

With more than 6.6 billion people living on the planet today, who knows that 70,000 years ago, harsh droughts continued to dramatically depress human populations and push us to the brink of extinction. A study published April 25 identified this question.

Analysis of these studies shows that 70,000 years ago, the human population declined to only about 2,000 people, living as separate small groups in Africa before returning to the beginning of the Stone Age.

'But it is also the harsh environmental conditions that bring people together, increase population and emit residence all over the world. A human epic epic has been recorded faithfully on our DNA, 'said Spencer Wells, director of the Genetic Graph Program.

This study uses a special gene complex called mitochondrial DNA, which is transmitted from mother to child, to trace from the modern man about a single person called 'Mitochondrial Eve' living in Africa about 200,000 years ago. .

At the same time, this study looked at the mitochondrial gene complex of the Khoi and San people in Africa, who may have separated others around 90,000 - 150,000 years ago.

Mr. Spencer further explained that this study clarified the extraordinary power of genetics and has since uncovered some of the key facts in human history.

After 'resurgence', humans began migrating from Africa to reside on the rest of the world about 60,000 years ago. However, humanity is in the period between 'Eve' and this migration has not been decoded much.
