it could be for many different reasons, like food is scarce or weather
Because they are travlers
The animals adapt gradually and separately to their new environments on either side of the mountain
Animals move from one place to another in search of food and to protect themselves from their enemies.they also move to escape from the harsh climate. By -- jithin sunny
Animals can move when the environment changes. (The "environment" is always changing; it has never been static.) Plants can't move. Some plants, such as the kinds that have burrs, can send their offspring away; an animal brushes against the plant, the seeds attach to the animal's fur, and later on the animal scratches the seed off to fall in a new location.
Movement is an important adaptation of some animals because when environments that were home to the animals are destroyed or taken over the animal can move to another ecosystem.
Because they are travlers
Animals tend to move very quickly whereas plants do not. This is because plants are rooted into their environments and only their seeds can travel.

It depends on the type of animal. Different animals = Different environments! ~JJ
Tasmanian devils are completely wild animals. Humans cannot "adapt" them, but they can create new environments for them.
Mutations are changes in DNA. Most are neutral or beneficial. Mutations have allowed animals to adapt to new environments and new species to evolve.
Early humans were nomadic because they followed food sources such as animals and plants for survival. Moving to new areas also helped them avoid resource depletion and competition with other groups. Additionally, migration allowed them to adapt to various environments and develop new skills.
They prefer moist environments
this question makes no sense for other animals are not environments
they can travel over land because they do not need to lay eggs in water
