This is an example of Morphological and structural adaptation
Explanation:
The morphological and structural adaptation is an anatomical adaptation, where living beings exhibit some characteristics that allow them to survive according to the environment in which they are, either promoting a camouflage, or resembling animals that are dangerous to frighten possible predators.
An example of this can be seen in the question above, where the hare, in order to survive and reproduce, allow the hair to become white as snow, and can camouflage themselves in the environment in which they are.
There are now many small soay sheep in Scotland because the winters are not as brutally cold as they use to be. The climate in Scotland has been warming therefore the sheeps of small stature can easily survive now in Scotland, which was not possible in earlier years.
