An April 4 New York Times Magazine piece examined the science and the controversy surrounding the long-wondered question of whether homosexuality exists in lower species. One expert quoted in the piece was Dr. Marlene Zuk, a biology professor at the University of California at Riverside, author of “Sexual Selections: What We Can and Can’t Learn About Sex From Animals.” Dr. Zuk joins the Petcasters to discuss.
