Summarize How Evolution Is Related To Geologic Change The evolution of amphibians. By the Devonian period two major animal groups dominated the land: the tetrapods (4-legged terrestrial vertebrates) and the arthropods, including arachnids and wingless insects. The first tetrapods were amphibians, such as Ichthyostega, and were closely related to a group of fish known as lobe-finned fish e.g. Eusthenopteron. This self-guided field trip
