Why baboon males resort to domestic violence. Duke Today, Jan. 18, 2017. Some baboon males vying for a chance to father their own offspring expedite matters in a gruesome way — they kill infants sired by other males and attack pregnant females, causing them to miscarry, researchers report. Infanticide has been documented in other animals including baboons, lions and dolphins, but rarely feticide. The perpetrators are more prone to commit domestic violence when forced to move into a group with few fertile females, the study finds.
