Sperm-female coevolution: mechanisms, models and theoretical implications
Currently, the primary interests of the Pitnick Lab include: (1) understanding how and why postcopulatory sexual selection drives evolutionary diversification of sperm and female reproductive tract traits, (2) exploring the extent to which ejaculate-female incompatibility contributes to reproductive isolation and species formation, (3) using comparative methods to examine the relationship between reproductive and life history evolution, (4) the evolution of sperm cooperation, (5) the evolution of genitalic form and (6) the causes and consequences of variation in brain size.
