As in humans, some studies have also found sex biases in play type among primates. Brown and Dixson (2000) studied infant rhesus macaques in the first 6 months of life and found that males initiated play and engaged in more rough‐and‐tumble and chasing play than females. The propensity for males to exhibit more rough‐and‐tumble play has also been found among blue monkeys (Forster and Cords, 2005), patas monkeys (Rowell and Chism, 1986), Japanese macaques, and olive baboons (for review see Brown and Dixson, 2000).

Immature chimpanzee males were found to engage in more object‐oriented play than females (Koops et al., 2015), but female youngsters at one study site perform a specific behavior called “stick carrying,” in which a stick is cradled and carried in a form of play mothering, significantly more often than young males (Kahlenberg and Wrangham, 2010). Female biases in other forms of play parenting, such as interest in or attempting to interact with and carry other infants, are also widespread (e.g., western lowland gorillas, Meder, 1990; rhesus macaques: Lovejoy and Wallen, 1988; bonnet macaques: Silk, 1999; blue monkeys: Cords et al., 2010). Thus, there are diverse lines of evidence for sex differences in play behavior in many primate species. Indeed, these sex differences in play may represent evolved predispositions that reflect patterns of mating competition and parental investment that are shared by most mammalian species.
