Tetrapods are vertebrate animals having four feet, legs or leglike appendages. Amphibians, reptiles, dinosaurs/birds, and mammals are all tetrapods, and even the limbless snakes and whales are tetrapods by descent. The earliest tetrapods radiated from the Sarcopterygii, or lobe-finned fish, into air-breathing amphibians. The first tetrapods are now thought to have evolved in shallow and swampy freshwater habitats, towards the end of the Devonian, a little more than 365 million years ago.
This documentary walks through our early understanding and discoveries regarding the evolution of tetrapods. The list of known fossils possessing transitional features continues to grow.
