Eskimos have a remarkable ability to work in the cold without gloves and not suffer decreased skin blood flow. Does this prove that there is a genetic difference between Eskimos and other people with regard to this characteristic?

Answer 1

• The Eskimos are able to work in the cold weather without gloves. Their skin does not suffer from a decrease in blood flow. This enables them to continue working in the cold, without losing sensation in their hands.
  
• Moreover, it could be a genetic difference between the Eskimos and other people, but it is not proof of a genetic difference.
  
• In addition, another possible reason could be that the Inuit Eskimos have adapted to their environment is that they have undergone acclimatized to the cold weather.
