Ancient hominids may have been seafarers

Hand axes excavated on Crete suggest hominids made sea crossings to go ‘out of Africa’

By Bruce Bower, Science News, Vol.177 #3 (p. 14), January 30th, 2010 [here]

ANAHEIM, Calif. — Human ancestors that left Africa hundreds of thousands of years ago to see the rest of the world were no landlubbers. Stone hand axes unearthed on the Mediterranean island of Crete indicate that an ancient Homo species — perhaps Homo erectus — had used rafts or other seagoing vessels to cross from northern Africa to Europe via at least some of the larger islands in between, says archaeologist Thomas Strasser of Providence College in Rhode Island.

Several hundred double-edged cutting implements discovered at nine sites in southwestern Crete date to at least 130,000 years ago and probably much earlier, Strasser reported January 7 at the annual meeting of the American Institute of Archaeology. Many of these finds closely resemble hand axes fashioned in Africa about 800,000 years ago by H. erectus, he says. H. erectus had spread from Africa to parts of Asia and Europe by at least that time.

Until now, the oldest known human settlements on Crete dated to around 9,000 years ago. Traditional theories hold that early farming groups in southern Europe and the Middle East first navigated vessels to Crete and other Mediterranean islands at that time.

“We’re just going to have to accept that, as soon as hominids left Africa, they were long-distance seafarers and rapidly spread all over the place,” Strasser says. The traditional view has been that hominids (specifically, H. erectus) left Africa via land routes that ran from the Middle East to Europe and Asia. Other researchers have controversially suggested that H. erectus navigated rafts across short stretches of sea in Indonesia around 800,000 years ago and that Neandertals crossed the Strait of Gibraltar perhaps 60,000 years ago. … [more]
