The genitals of male seed beetles are extraordinarily spiny, helping to anchor the males inside females as they attempt to impregnate them. Unfortunately, these spikes damage the females, potentially compromising the entire reproductive mission.  Now scientists have discovered an evolutionary arms race with these beetle genitalia, with female genitals growing tougher the spinier the male genitals are. The speed at which genitals change in this battle of the sexes could help shed light on how new species evolve.  A similar battle of the genitals  among waterfowl was announced in April. ...
