The theory of evolution provides a number of insights:
-it tells us how the species are related

The niche is considered an animals role in an environment. It describes not only the habitat that the animal lives in, but what the organism does within the habitat. All abiotic and biotic factors are included in a niche, including abiotic factors like the temperature the organism can survive in, as well as the amount of sunlight and water needed for the organism to survive. Biotic factors include what the food source is for the organism, and the predators of the organism.
