Adaptation of mammals to different environmental conditions.

Mammals live in various ecological systems. They can be found in the desert, in the forest, in the sea and ocean, in the tundra and other places. They all have different adaptations to the environment. It can be a thick body coat that protects from the cold, or a streamlined body for swimming, or a skeletal structure for fast movement. Any part of the body, its features, can be considered as an adaptation to the environment. Their difference in different species is associated with evolutionary development.
