The struggle for springs has played an important role in human evolution

One of the main drivers of human evolution could be competition for the springs is the only source of fresh water during the millennial ages arid climate in Africa.

To such conclusions scientists have come, considering the geological and hydrological history of Olduvai gorge (Tanzania), where they found the remains of a skillful person.

A study published in the journal PLoS ONE, and briefly its contents stated in the press release of the University of New South Wales.

1.8 million years ago, is extremely significant for the evolution of hominin era, suitable for drinking water in lakes and rivers of the basin, Olduvai actually was not (ponds have dried up and became salty). However, as recognized scientists, keys, fed by underground waters, never exhausted a large number of centuries, even in conditions of constant drought. These informants were the main water resource. During periods of high humidity springs could be used as a transit point, where hominini stayed during travels in Africa and beyond.

For springs group hominin struggled both with each other and with other animals. Specifically, limited access to water has created the necessary conditions for natural selection, which was won by individuals, which turned out to be better ready to find sources and to ward off rivals, said study co-author Gail Ashley (Gail Ashley).
