  Practitioners of feminist philosophy of biology use gender as an analytic category to conduct philosophical investigations of the biological sciences. Feminist philosophy of biology deploys feminist philosophical methods to examine the categories of sex and gender (sex and gender will be explained below) and its focus can range from considerations of particular biological knowledge claims to considerations of foundational concepts and methodologies in biology, the philosophy of biology, and the philosophy of science. In doing so, feminist philosophers of biology often show that the philosophical investigations of a particular science are intertwined with both ethics and politics.
