Answer:
Explanation:
If people indigenous to cold areas increase heat production in response to cold exposure to a larger extent than people from the tropics, they can be considered metabolically cold adapted. Metabolic adaptation, can go hand in hand with higher mean skin temperature without an increase in body core temperature.7 Metabolic cold adaptation is indeed present in people from temperate and arctic regions, since the shivering response to cold is considerably higher compared to African people. This, however, does not answer the question if those adaptations are phenotypic of genotypic. Adams and Covino36 subjected nude Negro, Caucasian and Eskimo males to an air temperature of 17°C. After 55 minutes of exposure, both the Caucasian and Eskimo subjects demonstrated an average rise in metabolism of 26 W/m2 body surface area above control levels of 46 and 64 W/m2, respectively. Negro subjects showed an increase in body heat production of only 12 W/m2 after 85 minutes in the cold room.
