But why are men and women so different from one another? Although sex can be fun, and is necessary for reproduction, there are costs associated with sex, such as time, energy and even potential exposure to pathogens. Many other species have evolved sexual recombination as a method of reproduction, and most species have two sexes. What are the implications of this kind of system?

McMaster psychologists Mel Rutherford and Sigal Balshine will ponder the evolution of sexuality, and muse about why we aren't all hermaphrodites at McMaster University's inaugural meeting of MACafi Scientifique. The Cafi Scientifique approach complements more traditional lecture series, such as Science in the City, providing a forum for discussion that gives non-academics a chance to weigh in on science-related topics. It is intentionally informal (which is why it's held in a bar or cafi) to engage the public. For the price of a cup of coffee or a glass of wine, you can argue the latest scientific talking point with some of Canada's leading scientists. It's like the salons of Paris, without the corsets and the big hair.

McMaster's Cafi, sponsored by the Faculty of Science, is one of the first in Canada. MACafi Scientifique will premiere at The Bean Bar in Westdale, on Wednesday, March 16, beginning at 5:30 p.m. There is no admission fee. Organizers hope the event will become a monthly series starting in September.
