Genital coevolution in vertebrates and the overlooked female
Dr. Brennan studies the functional morphology of genitalia in vertebrates to understand their complex evolution. She is interested in coevolution because the mechanical interaction of genitalia suggests that male and female must fit together to make copulation possible, however, her work has highlighted the gaps in our understanding of female genitalia. She has worked with birds, dolphins, bats, sharks, skates and more recently alpacas and snakes, discovering amazing adaptations in all these groups.
