The eggs could also "breathe" and cope with wastes, allowing the eggs and the amniotes themselves to evolve into larger forms. The amniotic egg represents a critical divergence within the vertebrates, one enabling amniotes to reproduce on dry land—free of the need to return to water for reproduction as required of the amphibians.

Amniotic eggs are the evolutionary separation between amphibians and reptiles. Amphibians lay eggs that must remain moist. Lacking a protected fluid-filled cavity requires the non-amniotic eggs of amphibians to remain in water. With the development of the amniotic egg, reptiles were able to lay their eggs on land.

Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. But thanks to the amniotic egg, reptiles can lay their eggs nearly anywhere on dry land.

Amniotes evolved during the late Paleozoic era. The characteristic that sets amniotes apart from other tetrapods is that amniotes lay eggs that are well-adapted to survive in a terrestrial environment. The amniotic egg generally consists of four membranes: the amnion, the allantois, the chorion, and the yolk sac.

Amniota: Amniota, a group of limbed vertebrates that includes all living reptiles (class Reptilia), birds (class Aves), mammals (class Mammalia), and their extinct relatives and ancestors. The amniotes are the evolutionary branch (clade) of the tetrapods (superclass Tetrapoda) in which the embryo develops
