Early Man In Australia Even Earlier

In an alluvial deposit in Western Australia, Mance Lofgren and John Clarke have discovered more than 30 stone tools dating back more than 100,000 years. Previously, the first men were thought to have invaded Australia only 40,000 years ago.

Comment. A similar situation exists in North America, where many discoveries of tools in ancient geological deposits are hotly debated.
