Neanderthals 'dived in the ocean' for shellfish

New data suggests that our evolutionary cousins the Neanderthals may have been diving under the ocean for clams, BBC reports.

It adds to mounting evidence that the old picture of these ancient people as brutish and unimaginative is wrong.

Until now, there had been little clear evidence that Neanderthals were swimmers.

But a team of researchers who analysed shells from a cave in Italy said that some must have been gathered from the seafloor by Neanderthals.

The findings have been published in the journal Plos One.

The Neanderthals living at Grotta dei Moscerini in the Latium region around 90,000 years ago were shaping the clam shells into sharp tools.

Paolo Villa, from the University of Colorado, Boulder, and colleagues, analysed 171 such tools, which all came from a local species of mollusc called the smooth clam (Callista chione). The tools were excavated by archaeologists at the end of the 1940s.
