Beyond Difference: A Biologist's Perspective

This piece addresses some of the challenges to social scientific thought originating from the field of evolutionary psychology and from social scientists committed to making biological arguments an important component of the sociological discussion of gender. I provide my own biological perspective on these contemporary discussions, noting especially the different kinds of explanatory value one can expect from particular kinds of argument. I also call for the application of stricter scientific standards to arguments about the evolution of sex differentiated human behaviors. I introduce some basic genetic concepts, such as the norm of reaction, which focus attention on the interaction between genes and environment during intra‐generational development. Finally, I challenge the idea that there is a necessary correlation between hormone levels and reproductive behavior in vertebrates.
