According To A Study The Human Race Was Near Extinction

The number of people from the planet has been reduced drastically in the latter by 70,000 years, and the human race has been threatened with disappearance. An extensive genetic study shows that, because of the drought, in that time people lived in small groups and isolated in Africa, the total number of people was only of 2,000 individuals.

70,000 years ago , people lived in small groups and isolated. East Africa has been passive to a hard drought ago 135.000-90.000 years and climatic conditions probably have produced changes in the number and type of men organization.

Researchers have reached these conclusions after having analysed the genetic material of some populations of southern Africa. "The study shows the extraordinary power of genetics to remove some light on key events for our species," said Sepncer Wells, a researcher of the National Geographic Society.

Today, around the world live more than 6.6 billion people.
