Abstract
Tetrapods are vertebrate animals having four limbs. Amphibians, reptiles, birds and mammals are all tetrapods; even snakes and other limbless reptiles and amphibians are tetrapods by descent. The earliest tetrapods evolved from the lobe-finned fishes in the Devonian. They are now a dominant part of the terrestrial fauna, representing all known larger land animals. Some groups have even returned to an aquatic existence, including the largest animal known, the blue whale. The evolution of the first tetrapods marked the moment when the two basic forms of vertebrates, fishes and tetrapods, diverged. This transition, from a body plan for breathing and navigating in water and a body plan enabling the animal to move on land, involved a series of changes taking place throughout most of the 57 million years that make up the Devonian period. While it is one of the most profound evolutionary changes known, it is also one of the best understood, largely thanks to a number of amazing fossil finds in the late 20th century combined with improved phylogenetic analysis.
