Margie Profet
Margaret J. "Margie" Profet (born August 7, 1958) is an American evolutionary biologist with no formal biology training who created a decade-long controversy when she published her findings on the role of Darwinian evolution in menstruation, allergies and morning sickness. She argued that these three processes had evolved to eliminate pathogens, carcinogens and other toxins from the body.
