Archaeologists working in a seafront cave in Portugal have discovered the remains of various shellfish, including numerous brown crabs, where Neanderthals lived around 90,000 years ago. The finding suggests that Neanderthals were cooking and eating crab and shellfish meat.
More specifically, according to the new study published in Frontiers in Environmental Archaeology, the Neanderthals living on the Iberian Peninsula hunted and ate mostly larger adult crabs. This suggests Neanderthals knew larger crabs provided more sustenance.
