Document Summary

Discuss the different hypotheses about the origin of modern amphibians. Contrast form and function of the three groups of living amphibians. The main characteristics of lissamphibia and the distinguishing features between the three extant orders. The problems relating to the origins of modern amphibians. Describe adaptations that enabled successful colonization of the terrestrial habitat. Describe the changes in the skeleton that helped with terrestrial locomotion in tetrapods. The main adaptations associated with terrestrial life in amniotes. Describe the characteristics of mammals and how they helped them succeed as a group. The trends in synapsid evolution that led to mammals. Highlight the diversity of extinct and living sauropsids. Describe the adaptations that enabled flight, crawling and gigantism within sauropsids(sauropsids (reptiles and birds)) Amniote: the amniotes are a group of tetrapods (four-limbed animals with backbones or spinal columns) that have a terrestrially adapted egg. The key adaptations that enabled sauropsid evolutionary radiations.
