Humans are genetically modified, disregarding a cold price of 30 degrees C

Although eating a lot of whale meat and seals, this ethnic group does not worry about obesity or heart disease.

For many people, the winter with freezing weather, the wind whistled constantly is extreme. But with the Inuit in Greenland Island, living with the winter for 6 consecutive months is too normal.

Dog tractors are the main means of transportation in Greenland.

For decades, anthropologists and biologists have studied the strange Inuit race when they can resist the cold winter. A study published in Molecular Biology found the cause of this extraordinary tolerance: unusual genetic changes in the Inuit.

The genes that exist in the Inuit originate from an ancient group of people living half a million years ago. Most people in the world do not have this gene. Because of the richness of the 'superman' gene, it is easy to understand why the Inuit can tolerate the cold of 30 degrees Celsius for several consecutive months.

The magic gene helps the Inuit to survive a mechanism of fat breakdown to warm the body. They can get more fat than usual without worrying about being obese or. Their favorite food is whale meat and seals. These are high-fat foods and provide a great deal of protein to the Inuit.

The Inuit carry the gene "superman" to resist the cold.

Rasmus Nielesel, a scientist at the University of California, USA, said: "The special Inuit gene helps them withstand cold weather in the polar regions." Professor Rasmus said he has done a lot of research on human genes, and found that in regions like South America and East Asia, there are also genetic changes to suit the living environment. However, no strain of humans has the same genetic variation as the Inuit.

Professor Rasmus hopes that better understanding of cold tolerance genes will help people solve the problem of climate change in the future when extreme weather events will become more and more.
