A niche, on the other hand, reflects an organism's behaviors and other variables like wind or temperature that affect those behaviors. Evolution helps species adapt over time until it evolves to successfully fill a place within a certain environment. Some species evolve so well, however, that it may no longer be suited to another environment. It is also possible for similar environments to help similar species evolve that do not live close together. For example, cattle in North America and wildebeests in Africa are similar because they evolved in similar niches in their environment
