Surveys development in a range of vertebrate and invertebrate systems to reconstruct the common bilatorian ancestor, and elucidate the developmental genetic changes underlying animal diversification. Lab focuses on vertebrate embryos and explores key methods in evolutionary developmental biology including in situ hybridization, embryo microinjection, and transgenesis. Prereqs., EBIO 1210, 1220 and 2070, or MCDB 1150 and 2150. EBIO 4440, EBIO 5440, MCDB 4441, and MCDB 5441 are all the same course. Prerequisites: Restricted to Graduate Students only.
