Explanation:

Acoording to Bergmann's and Allen's rules, the appearance of the humans directly depends on the environment in which they live. The main reason for this rules are that the humans have to develop certain advantageous traits in order to be able to survive in certain type of environment. The Yupik people of Alaska are a nice example of this. The climate in Alaska is very cold. There's lot of snow and long winters with freezing temperatures. The winds are also strong and cold. This has resulted in the Yupik people developing shorter bodies. They also became stockier, with wider chest, larger lung capacity, and also preserving fat below the eyes. These adaptations have been result of the environment, as the type of body they have helps in preserving the heat. The fat below the eyes helps prevent damage to the eyes from the cold, and the larger lung capacity helps them in breathing in colder air.
