The evolution of the amniotic egg is significant because it allowed tetrapods (four-limbed animals, including reptiles, birds, and mammals) to reproduce away from water bodies, thus not tying them to aquatic environments for the purpose of laying eggs and embryonic development. This adaptation was crucial for the colonization of terrestrial environments.
