Scientists: Stone tool find shows humans walked through Red Sea | Earth Times News   Leave a comment

Tuebingen, Germany – A stone tool found in an Arabian archaeological dig has revealed that human beings spread out of Africa twice as long ago as earlier believed, scientists said Thursday.

The find shows not only that humans migrated out of Africa, the cradle of humanity, 125,000 years ago, but also that they probably walked through what is now the Red Sea. Dry land would have connected Africa and the Arabian peninsula at the time.

The tool is a hand adze, a primitive stone chopper held in the palm of the hand. It was found in Jebel Faya, east of Dubai.

The research, led by archaeologist Hans-Peter Uerpmann of Tuebingen University in Germany, was published Thursday in the journal Science.

Past theories assumed humans did not leave Africa till 60,000 to 70,000 years ago, spreading to the mouth of the Nile.

The team argued for a new hypothesis about how humans spread through fertile zones without crossing deserts or seas.

Sea levels were still 100 metres lower at the time because water was locked up in glaciers, so jumping the southern Red Sea 140,000 years ago would have been easy. Humans then spread to Dubai.
