Is Betsy merely an overly picky girl destined for spinsterhood? No. Betsy is just observant — observant enough to preserve her species. You see, Betsy is a Sprague Dawley rat, a variety commonly used in biological experiments and the very kind used by Andrea Gore and David Crews of the University of Texas, Austin and Michael Skinner of Washington State University, Pullman, who have found something amazing and scary in a mate-selection experiment very similar to Betsy’s speed-dating scenario.

In the experiment, female Sprague Dawley rats were exposed to potential male suitors, some of which were descended from one great-great-grandmother rat who had been given a high dose of the fungicide vinclozolin when she was pregnant. Vinclozolin, used worldwide on a variety of agricultural products including wine grapes, is banned in Scandinavian countries, but the EPA continues to allow its use in the United States on certain crops.
