Neandertals dove and harvested clamshells for tools near Italy’s shores
Often typecast as spear-wielding mammoth killers, some Neandertals were beachcombers and surf divers, researchers say. At Moscerini Cave, located on Italy’s western coast, Neandertals collected clamshells on the beach and retrieved others from the Mediterranean Sea, say archaeologist Paola Villa of the University of Colorado Boulder Museum of Natural History and her colleagues. Our close, now extinct evolutionary relatives waded or dove into shallow waters to collect shells that they sharpened into scraping or cutting tools, the researchers report January 15 in PLOS ONE. Of 167 clamshells with sharpened edges that previously were excavated in the cave, 40 displayed shiny, smooth surfaces characteristic of living clams taken from the seafloor, Villa’s team says. The remaining shells featured dull, worn surfaces, indicating that these finds had washed up on the beach and were gradually ground down before Neandertals used them as tools. Earlier dating of animal teeth unearthed near sharpened clam shells in Moscerini Cave suggested that Neandertals lived there roughly 100,000 years ago, at a...
