Natural selection

In wildlife there are many different types of natural selection. For example artic foxes' coats turn brown in the summer and white in the winter. If the coat would remain brown then predators would find it easier to see the foxes. A lot of species need natural selection to survive. Every animal has a variety of traits that are necessary for their survival. If you put a polar bear in the forest with a brown bear, the hunters would find it easier to hunt the polar bear because of their coats. Then the brown Bears will have offspring and the polar bears would try to evolve to adapt into the forest.
