Organismal and Evolutionary Biology
Evolution is the guiding force that generates the particular anatomy and physiology
of every species. Studies of evolutionary biology help us to understand the mechanisms directing
the development and divergence of species, and how changing ecosystems impact the
genetic regulation of form and function, health and disease, survival and reproduction.
PCOM’s interdisciplinary group of researchers studies multiple subfields of comparative
vertebrate morphology, including biodiversity and systematics (nomenclature and relationships),
evolutionary developmental biology, paleobiology (anthropology and paleontology) and
physiology. The investigators utilize model organisms to understand factors that both
drive and impact the divergence and evolution of many species, including humans.
