Abstract and Biographical information

Abstract: A Process Theory of Biological Sex

My first thesis is that the statement ‘this species has n sexes’ is properly a statement about a species, a set of populations united in a pattern of ancestry and descent. It is a statement about the role that the number of sexes (n) plays in modelling the evolution of that species. Choosing the right n lets us explain and predict many other features of the species. Each animal species studied to date each uses one or more of three systems for making new individuals: two sexes in discrete individuals, two sexes combined in one individual, and asexual reproduction. So no n greater than 2 has yet been observed. My second thesis is that the number of sexes is not a distributive property – it does not apply to the individuals that make up a species. This is because the biological sex of an individual is a process, and a process which can follow many different trajectories. By way of illustration, the Eastern Blue Groper has two sexes, and a life cycle in which individuals first become female and then later switch to male, but it does not follow that for a specific fish on a specific day there is a definitive answer to whether that fish is male, female or neither. In conclusion, I will suggest that the number of biological sexes in humans is a matter of little if any relevance to the many pressing ethical and political questions about sex and gender in contemporary society.”
