High-fat diet made Inuits healthier but shorter thanks to gene mutations, study finds

For evolutionary biologists, the best experiments are those already going on in nature. The different conditions in which humans have lived for tens of thousands of years have made us adapt and change. Now a new study published in Science shows that such adaptation has led to genetic mutations in Greenlandic Inuits that help them counteract the bad effects of their high-fat diet, based heavily on fish and marine mammals.
