The adaptation of the sled dog best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.
Explanation;
-The bodies of sled dogs are covered with two coats of hair that work together to provide a double layer of warmth. The under layer is very short and the dog sheds it in the spring to keep from overheating during warmer temperatures.
-During the colder winter months, this under layer works as an insulator against the dog's skin to keep his body warm and his core body temperature consistent.
