New evidence suggests Neanderthals gathered clam shells and volcanic rock from the bottom of the Mediterranean , which they forge into tools . The study is yet more evidence that Neanderthals often ventured into the water , and it add to the body of research showing that they were nothing like the unintelligent , uncoordinated clods they ’ve long been portrayed to be .
Researchers have previously uncovered evidence of Neanderthals tap marine resources , namelyfish . The full extent to which these primitive humanity occupy reward of the sea , however , is not full know .
A newpaperpublished in PLOS One offer further evidence that Neanderthals did n’t shy away from the water , showing they gathered buck shells and volcanic rock music from a beach in what is now Italy . The author of the new sketch , led by Paola Villa from the University of Colorado , say a significant portion of the clam shells were compile as unrecorded animals , which postulate the Neanderthals to wade or even plunge in shallow water . These artifact date back some 90,000 to 100,000 years to the Middle Paleolithic , predate the reaching of anatomically forward-looking homo to Europe by around 60,000 years .

These artifacts were found at the Grotta dei Moscerini situation in Italy , which was once a cave that overlooked the Mediterranean Sea . Found in the 1930s , Grotta dei Moscerini is one of two sleep with Neanderthal sites in Italy , and it undergo all-encompassing mining after the Second World War . Sadly , the cave is no longer approachable because highway structure work in the seventies buried the entrance .
Thankfully , the artifacts and fossil pull in from the site , include mollusk , animal tooth , and sediment , allowed scientist to see the site during the former 1990s . For the unexampled study , Villa and her colleagues re - visited some of these artifacts , include 171 modified shells , where are kept at museum in Anagni and Rome .
cheeseparing inspections of these clam shell , all go to the Mediterranean species Callista chione , suggests they were fashioned into scrapers . Many of these shells were collected from the shore , but a significant portion were pucker immediately from the seafloor . The research worker know this because beach specimen are distinct from specimens that were collected as live animals ; telltale signs include the degree of refulgency on the outer valve , the degree of saving as seen on both the interior and external surfaces , trace of encrust marine organisms , and sign of abrasion on the hinge . This method acting was spring up by Carlo Smriglio , a atomic number 27 - author of the young field of study and a researcher at the University of Rome .

In an email to Gizmodo , Villa provide further details .
“ The outer shells of live animals living in the sea are shiny , ” she said , whereas the “ beach specimens exposed to the Sun have an opaque and patinated [ glossy ] surface . ” Earth’s crust inside the shell valve left behind by marine organism “ intend the brute was dead , ” and the “ two valve were opened so the shellfish was deadened in the ocean and later taken by undulation and thrown on the beach , ” say Villa . “ If incrustation are on the outer case , it means that they imprint when the animate being was alive in the ocean , ” she add together .
In total , 40 of the 167 clam case identified as tool were gathered by Neanderthals from the seafloor , which number to almost 24 percentage .
The same sedimentary bed also give volcanic pumice gem , which could have also been used as scraping tools . The authors decipher the geographic lineage of these pumice stone stones to catch fire volcanoes in the Gulf of Naples , which is site 70 km ( 43 miles ) from Moscerini beach . Strong sea flow likely transported the stones to the Moscerini beach website , according to the paper .
In this case , it ’s likely that Neanderthals either waded or plunk powerful into the water to seek for and get together clam shells .
These lolly “ tunnel in the sand , but their syphon , which they postulate for course , excreting , and reproducing , ” is visible , Villa tell Gizmodo . “ If you see the siphon , then you know that there is a shellfish and you’re able to use your hired man to scoop out the sand . ” And by putting their heads under water supply , the Neanderthals would ’ve been better able to see what they were doing , she enounce .
That Neanderthals expend a portion of sentence underwater is not all lurid . Evidencepresented in 2019 exhibit that some Neanderthals had abnormal bony growths in their ear canal , a precondition sometimes referred to as swimmer ’s spike or surfer ’s pinna . This is often seen in mass who partake in body of water sport in colder climate .
The young sketch “ confirms that Neanderthals had the broad cognition of environmental imagination by and large attribute to modern humans only , ” said Villa .

Interestingly , the sedimentary level turn back the clam shell was surprisingly free of traditional stone shaft . Villa said the Neanderthals may have opt the clam shells , as they are comparatively slight and sharp and well-heeled to re - sharpen , unlike flint tools . Another possibility is that the material need to build stone tools were scarce and Neanderthals twist to clam shells as an alternative , but Villa does n’t think this was the case , saying it was fairly well-to-do to just scoop up the shells from the seafloor .
The image of Neanderthals as hulking animal is now firm in the rearview mirror . archaeologic enquiry has replaced these outdated notions with a more nuanced scene , in which we can now conjure images of Neanderthalsfashioning jewelry from eagle talons , caring for individuals with physical disabilities , encounter in the mud as children , and now , complimentary - diving Neanderthals searching for clam shell . Archaic or not , they were decidedly human .
