Thinking about human kinds: Gender

An editor inserted an error into this piece -- it refers to the Y chromosome as a ``gene.'' (Overconfident editors are an occupational hazard of science writing.)

Otherwise, I think it has held up pretty well since it was written in 1996. The court tussles it predicted over the definition of male and female did, in fact, arise.
