Is it a happy accident, or an adaptation?
On the one hand we have the “Professor of Anthropology and Biology”:http://anthro.rutgers.edu/faculty/trivers.shtml at Rutgers University, who says — or will say, in some future issue of the _Guardian_ — that “If Steve Gould thought the female orgasm was a byproduct, you have to wonder how close he had ever been to that blessed event.”
On the other side, we have a “really fine piece of reasoning”:http://philbio.typepad.com/philosophy_of_biology/2005/06/lisa_lloyds_vie.html from the Arnold and Maxine Tanis Chair of History and Philosophy of Science and Professor of Biology, at Indiana University. I’m not being ironic. It’s a beautiful piece of argument; and I am interested that none of the papers here seem to have picked it up, or “her book.”:http://www.hup.harvard.edu/catalog/LLOCAS.html
The first person to comment that “more research is needed” will have a long time in which to consider the self-restraint that all the rest of us showed, when we didn’t leap to that conclusion.
