Neanderthals spent a surprising amount of time underwater [View all]

HUMANS 14 August 2019

Bony growths found in Neanderthals’ ears suggest that aquatic foraging was a big part of their lifestyle. This adds to evidence that Neanderthals adapted to life in several landscapes, including those near water.

Erik Trinkaus at Washington University in St Louis, Missouri, and his colleagues investigated the well-preserved ear remains of 77 ancient humans that lived in western Eurasia in the mid-to-late Pleistocene period.

They looked for dense, bony growths in the ear canals known as external auditory exostoses. These are often found in modern surfers and others who spend time in cold, wet and windy conditions, leading to the condition’s other name, “surfer’s ear”.

Trinkaus and his colleagues were surprised to find that around half of the 23 Neanderthals they studied had signs of these growths, which is at least twice as prevalent as in any of the other groups of ancient humans the team studied. This suggests that Neanderthals foraged in water for food and other resources – something that hasn’t been obvious from other archaeological evidence.
