Although we call erections "boners", anyone who has basic familiarity with human anatomy knows our slang deceives us — for unlike most mammals, men have no penis bones. For decades scientists have wondered, "Why no penis bone?" A new study published in Proceedings of the Royal Society might finally answer the mystery of what killed the penis bone: Monogamy.
