Why are reptiles important?

Answer 1

Some eat insects, which is beneficial to humans that live in undeveloped Nations, because insects eat crops and are a problem in rain season as that's when a lot of them come out.. I actually use to live in one, and they were important for that.. Some Reptiles eat rodents like rats(rodent) which is beneficial to humans, because, rats go all over people's houses.

Answer 2

is especially important for two reasons. First, the class Reptilia lies at the center of vertebrate history; the reptiles evolved from the amphibians (which themselves had originated from the fishes), and both birds and mammals evolved from the reptiles. Thus reptiles are concerned in three of the four major "jumps" (the class-to-class transitions) in vertebrate evolution. The distinction between the living representatives of two successive classes is always very clear, being based on a number of features of their anatomy, physiology, and embryology; the distinction between their fossil members, however, is inevitably less clear, not only because the distinction must be based almost entirely upon characters of the skeleton but also because there must have been animals with a mixture of the characters of both classes during the transitional period. These help elucidate the reasons for the jumps and the precise mechanism by which each occurred. Second, the Reptilia were the dominant class of land vertebrates (and were also important in the sea and in the air) during a very long period of the Earth's history. Knowledge of the extinct reptiles, their morphology and their habits, is vital to an understanding of the life of those times, of how the animals and plants and the physical environment reacted upon each other (paleoecology).
