Summary: | Tetrapod evolution spans the last 375 million years, beginning with the origin of limbed terrestrial vertebrates from finned fishes. The earliest tetrapods were amphibians that radiated during the Late Paleozoic; only three groups of highly specialized amphibians survive today. The development of an amniotic egg provided novel mechanisms to enhance embryonic growth and allowed eggs to be laid on land. Amniotes came to dominate Mesozoic and Cenozoic terrestrial faunas worldwide, generated powered aerial flight three times, reverted to aquatic habitats and the marine realm repeatedly, created endothermic temperature controls, evolved limbs for running, digging, and climbing, flew in water with |
