Question

How do inuits protect themselves from the biting cold weather?

Answer 1

The Inuit, the natives of Greenland, and their ancestors have been living in the extreme conditions of the Arctic for thousands of years and have been exposed to both cold annual temperatures and a traditional high-fat diet. We discovered that the Inuit genome has mutations in genes controlling how fat is metabolized, allowing them to physically adapt on a diet rich in omega-3 polyunsaturated fatty acids from marine mammals.
