Reptiles first arose from amphibians in the swamps of the late Carboniferous. Increasing evolutionary pressure and the vast untouched niches of the land powered the evolutionary changes in amphibians to gradually become more and more land-based.

Environmental selection propelled the development of certain traits, such as a stronger skeletal structure, muscles, and more protective coating scales became more favorable; the basic foundation of reptiles were founded.

The evolution of lungs and legs are the main transitional steps towards reptiles, but the development of hard-shelled external eggs replacing the amphibious water bound eggs is the defining feature of the class Reptilia and is what allowed these amphibians to fully leave water.

Another major difference from amphibians is the increased brain size, more specifically, the enlarged cerebrum and cerebellum. Although their brain size is small when compared to birds and mammals, these enhancements prove vital in hunting strategies of reptiles.

The increased size of these two regions of the brain allowed for improved motor skills and an increase in sensory development. Early reptiles[ edit ] An early reptile Hylonomus Mesozoic scene showing typical reptilian megafauna: The origin of the reptiles lies about — million years ago, in the swamps of the late Carboniferous period, when the first reptiles evolved from advanced reptiliomorph labyrinthodonts.

One of the best known early reptiles is Mesosaurusa genus from the early Permian that had returned to water, feeding on fish. The earliest reptiles were largely overshadowed by bigger labyrinthodont amphibians, such as Cochleosaurusand remained a small, inconspicuous part of the fauna until after the small ice age at the end of the Carboniferous.

The other branch, Sauropsidais itself divided into two main groups. One of them, the aforementioned Parareptilia, contained taxa with anapsid-like skull, as well as taxa with one opening behind each eye see above.

Members of the other group, Diapsidapossessed a hole in their skulls behind each eye, along with a second hole located higher on the skull. The function of the holes in both synapsids and diapsids was to lighten the skull and give room for the jaw muscles to move, allowing for a more powerful bite.Learn reptiles and reptiles biology amphibians with free interactive flashcards.
