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.
A graduate of Harvard University, where she received a political philosophy degree in 1980, and University of California, Berkeley, where in 1985 she received a bachelor's degree in physics, Profet returned to school in 1994, studying mathematics at the University of Washington in Seattle, where she was awarded a "visiting scholar" position in the astronomy department, an allied discipline. Several years later, she returned to Harvard, once again to study math.
When Profet won a MacArthur Fellowship in 1993, international media took notice. New York Times reporter Natalie Angier called Profet's theory that menstruation protected the female mammal's reproductive canals a "radical new view".Scientific American, Time, Omni, and even People Magazine all followed with in-depth profiles of the 35-year-old "maverick" scientific prodigy.
Profet went on to publish two equally controversial bestselling books, 1995's Protecting Your Baby-To-Be: Preventing Birth Defects in the First Trimester and a 1997 follow up, Pregnancy Sickness: Using Your Body's Natural Defenses to Protect Your Baby-To-Be. Supporters—including U.C. Santa Barbara anthropologist Donald Symons and U.C. Berkeley toxicologist Bruce Ames—considered her work a pioneering analysis of evolutionary theory in a never-before-studied, everyday context.
