In so doing, it adapts to its new environment and becomes different from the parent species. If a new population of the parent species, 2, moves into the area, it too will try to occupy the same niche as 1. However, the niche rule states that only one of a group of closely related species may occupy the same niche in a given habitat. Competition between species 1 and 2 ensues, placing pressure on both groups to adapt to separate niches, further distinguishing them from each other and the parent species. As this happens many times in a given habitat, several new species may be formed from a single parent species in a relatively short period of time. Darwin's finches are an excellent example of adaptive radiation....
