New Evidence Provides An Alternative Route 'Out Of Africa' For Early Humans

A team led by the University of Bristol shows that wetter conditions reached a lot further north than previously thought, providing a wet 'corridor' through Libya for early human migrations. The results also help explain inconsistencies between archaeological finds.

While it is widely accepted that modern humans originated in sub-Saharan Africa 150-200 thousand years ago, their route of dispersal across the hyper-arid Sahara remains controversial. The Sahara covers most of North Africa and to cross it on foot would be a serious undertaking, even today with the most advanced equipment.

World's Oldest Fossil Impression Of Flying Insect Discovered: Found In Suburban Strip Mall

While paleontologists may scour remote, exotic places in search of prehistoric specimens, Tufts researchers have found what they believe to be the world's oldest whole-body fossil impression of a flying insect in a wooded field behind a strip mall in North Attleboro, Mass.

During a recent exploration as part of his senior project, Richard J. Knecht, a Tufts geology major, and Jake Benner, a paleontologist and senior lecturer in the Geology Department, set out to hunt for fossils at a location they learned of while reading a master's thesis that had been written in 1929. With chisels and hammers, the team reached the shale and sandstone outcropping described in the paper. There they delicately picked away pieces of rock before reaching a section that yielded fossils. Just below the surface, they uncovered a fossilized impression of a flying insect.
