This course considers the evolution and diversity of amphibians and reptiles, emphasizing detailed discussions of aspects that illustrate general principles of organismal and evolutionary biology. As such, the course explores the volution and diversity of amphibians and reptiles (origins and phylogeny; diversity and systematics of extinct and modern forms), reproduction (development, metamorphosis, neoteny; phenotypic plasticity), communication and social behaviour  (Vocalizations, acoustic communication, sensory systems, reproductive behaviour, social behaviour and parental care). physiology (hibernation and cold tolerance; venoms and toxicology, defensive strategies), biomechanics (jaw mechanics; Locomotion, limblessness, arboreality, fossorial life, swimming), genetics (sex determination; Parthenogenesis and hybridization)  and ecology (predator/prey relations, population ecology, conservation and endangered species. The laboratories emphasize structure and identification of representative forms, especially local and North American species.
