The New York Times reports that stone tools discovered on the Greek island of Crete, and reported last month at an academic conference, are strong evidence for rethinking the maritime capabilities of early humans. The researchers who found the tools (hand-axes, cleavers, and scrapers) estimate them to be at least 130,000 years old; if they're right, humans have been traveling long distances at sea (Crete is 200 miles from the northern African coastline) for at least several tens of thousands of years longer than earlier believed.
