Neanderthals may have been shallow free divers, suggests a new study


Clams were useful as both food and tools.

There may be a little more evidence to suggest that Neanderthals waded, swam, and even dove to gather resources along the shores of the Mediterranean. A new study claims Neanderthals at a coastal cave in Italy waded or dove to get clamshells straight off the seafloor to make scraping tools.

Swiping seashells straight from the seafloor?
Neanderthals who lived at Grotta dei Moscerini around 100,000 years ago used the sturdy shells of Mediterranean smooth clams to make sharp-edged scraping tools. Clamshells wash up on beaches all the time, but University of Colorado archaeologist Paola Villa and her colleagues say that some of the worked shell tools at Moscerini look less like flotsam and more like someone scooped them off the seafloor while they were still fresh.

Shells that wash ashore after their former tenants die usually show signs of sanding and polishing, as they spend time being bounced along the sandy bottom by waves. Many also feature small holes where a marine predator drilled its way inside. But nearly a quarter of the 171 shells at Moscerini looked surprisingly pristine, aside from the changes made by Neanderthals.

If Villa and her colleagues are right, Neanderthals at Moscerini may have practiced free diving, and they certainly did a lot of wading. Mediterranean smooth clams usually live in at least half a meter (1.6 feet) of water, and usually more. They bury themselves just beneath the sand, and it’s easy to spot where their feeding siphons reach up to the water above. Neanderthals could have easily scooped them up by hand if they were willing to go deep enough.

Only makes sense that they would work to gather food from the ocean as well otherwise not much point cstanleytech Jan 2020 #1
