Question

Explain the adaptive value of a larger body size in a colder climate

Answer 1

It's colder the higher you go, the bigger you are the more heat you can retain not to mention that your lungs also get bigger so you can obtain more air cause the higher you are the less air there is.

Answer 2

To minimize heat loss

Step-by-step explanation:

Most mammals in colder climates have large body size to minimize heat loss. The smaller the surface area to volume ratio, the less the heat loss to the environment. Hence a large body size helps the organisms to conserve heat. This is known as Bergman rule.

Most mammals in cold climates have large compact bodies and shorter extremities than mammals in hotter climates.
