Systematic mapping of developmental milestones in wild chimpanzees

  • Patterns of milestone emergence in wild chimpanzees are broadly comparable to observations in the human literature.

  • As in humans, chimpanzee gross motor traits emerge on average before communication, social interaction and fine motor traits.

  • Later emerging milestones demonstrate greater inter-individual variation in the timing of the emergence.
