Alfred Romer was born in White Plains, New York, and studied at Amherst College and Columbia University. In 1934 he was appointed professor of biology at Harvard University. In 1946, he also became director of the Harvard Museum of Comparative Zoology.
Romer was very keen in investigating vertebrate evolution. Comparing facts from paleontologyPaleontology (palaeontology is the British spelling) is the study of the developing history of life on earth, of ancient plants and animals based on the fossil record, evidence of their existence preserved in rocks. This includes the study of body fossils, comparative anatomyAnatomy (from the Greek anatome from ana-temnein to cut up), is the branch of biology that deals with the structure and organization of living things; thus there is animal anatomy ( zootomy) and plant anatomy ( phytonomy). The major branches of anatomy in, and embryologyEmbryology is the science of the early development of organisms, between the one-cell stage (generally, the zygote) and the beginning of free living. Embryology therefore deals with the various steps necessary for the correct and complete formation of the, he taught the basic structural and functional changes that happened during the evolution of fishAtlantic herring, Clupea harengus one of the most abundant species in the world Photo A fish is a poikilothermic (cold-blooded) water-dwelling vertebrate with gills. There are over 27,000 species of fish, making them the most diverse group of vertebrates.es to primitive terrestrial vertebrates and from these to all other tetrapodSynapsida Sauropsida Amphibia A tetrapod ( Greek tetrapoda "four-legged") is a vertebrate animal having four feet, legs or leglike appendages. Since amphibians, reptiles, dinosaurs and mammals are all tetrapods, and even birds and snakes are tetrapods bys. He always emphasized the evolutionary significance of the relationship between the form and function of animals and the environment.
