Scientists have found early human migrants left Africa for Eurasia, across the Sinai peninsula and on through Jordan, over 80-thousand years ago. Researchers have proved there was a 'well-watered corridor' which funneled hunter-gatherers through The Levant towards western Asia and northern Arabia via Jordan.
An international team of scientists has found early human migrants left Africa for Eurasia, across the Sinai peninsula and on through Jordan, over 80-thousand years ago.
For this latest research, the team conducted fieldwork in the Jordan Rift Valley where they uncovered hand tools, known as 'flakes', on the edge of wadis -- now dry river channels which, tens of thousands of years ago, were full of water. The scientists used luminescence dating techniques to help establish the age of the sediment the tools were buried in. This method estimates how long it has been since sediment was last exposed to light.
Paul Carling, Professor of Geomorphology at the University of Southampton, comments:"It's long been thought that when the sea level was low, humans used a southern crossing, via the Red Sea from the horn of Africa, to get to southwestern Arabia. However, our study confirms there was a well-trodden passage to the north, across the only land-route from Africa to Eurasia.
"The paleohydrological evidence from the Jordan desert enhances our understanding of the environmental setting at that time. Rather than dry desert, savannah grasslands would have provided the much-needed resources for humans to survive during their journey out of Africa and into southwest Asia and beyond."Mahmoud Abbas, Zhongping Lai, John D.

Human disease simulator lets scientists choose their own adventureScientists have developed a device smaller than a toddler's shoebox -- called Lattice --that can simulate any human disease in up to eight organs (cell cultures from a human organ) or test new drugs without ever entering -- or harming -- the body. It is a major advancement from current in vitro systems, which can only study two cell cultures simultaneously.
