The use of brown fat to generate metabolic heat is mostly limited to small mammals. What is the basis of this adaptation?
A. Small mammals cannot grow enough fur to insulate their bodies.
B. Because of their large surface area to volume ratio, heat loss across the body surface is higher in small animals.
C. Small mammals do not have enough muscle to generate heat by shivering.
D. Large mammals have lost their brown fat through the course of their evolution.

The use of brown fat to generate metabolic heat is mostly limited to small mammals the heat loss over the body surface is greater in small animals due to their huge surface area to volume ratio.

Brown fat converts fat molecules and blood sugar (glucose) into heat and contributes to the regulation of body temperature. Brown fat is activated by cold temperatures, which causes a number of metabolic changes in the body. But the majority of our fat is white fat, which may store extra energy.

Heat loss over the body surface is greater in small animals due to their huge surface area to volume ratio.

Additionally, exposure to cold temperatures activates brown fat. Obese people cannot just start taking cold showers to lose weight without altering other aspects of their lifestyle. However, having a cold shower two or three times per week might help to boost metabolism.
