The clever ways Neanderthals got their fat long before modern humans

Neanderthals at Neumark-Nord, Germany, systematically transported and processed the bones of at least 172 large mammals to extract nutrient-rich "bone grease" nearly 125,000 years ago. This finding rewrites the timeline for large-scale fat processing, revealing unexpectedly complex resource strategies among Neanderthals.
