Infanticide, or murdering children of ones own species, is documented in a variety of animal species, including baboons: Lions and dolphins will both do it. We may infer that most monkeys and apes cry, particularly as newborns, if we define crying as vocalizations produced in response to painful conditions. Rejection was demonstrated through strong jets of air or blunt spikes forcing baby away. At any rate, infanticide and cannabilism are extremely rare among chimpanzees, says Hulme. The only thing that makes the work tolerable is that tamarin troops cooperate to rear young, but the conditions have to be right. Young males and females have oc- casionally been observed mounting their mothers; males sometimes intromit and thrust. The reactions of the babies were quite amazing actually, after rejection, the monkeys would cling again to the mothers even tighter than they did before. .

Diana monkeys, seen in Clever Monkeys, are some of the most clever monkeys when it comes to language. Monkeys are taught to forage for food, which is why they steal things like peanuts, crisps, and bananas. "This is the first study for any mammal that presents evidence that natural variation in available milk energy from the mother is associated with later variation in infant behavior and temperament," said Katie Hinde, the study's lead author and anthropologist at the California National Primate Research Center and the nutrition laboratory at the Smithsonian's National Zoo.
