Neanderthals ran 'fat factories' 125,000 years ago (2025)

Scientists discovered evidence that Neanderthals 125,000 years ago had a diet rich in fat, suggesting they had a 'fat factory' to process it. This finding matters as it challenges previous assumptions about Neanderthal diets and lifestyles. The research has implications for understanding human evolution and the origins of modern human diets. Engineers may be interested in the application of this research to modern food processing and nutrition.
