Chimpanzees: research first started with chimps in 1960s, jane goodall. Females mate with multiple males; child not associated with a father. Child-rearing is a learned behavior; chimps raised by humans don"t know to take care of their offspring. Using a wrist-flicking technique that took even humans a few times to try and imitate properly. Takes a young bonobo 6-8 years in order to learn: both males and females rear children technique. Exclusively nurse until 2 years of age; at 2, they begin to eat solid food. 4-6 years old, weaned; less nursing and more solid food. Optimal size for environment they live in. Social rules learned within the family, but extended to members of the troop. Grooming: not for pulling parasites, rather to touch. Humans use language rather than grooming to interact. To get the attention of the entire troop all at once. Danger, food, scared/upset, reassurance, sexually receptive female. Bonobos have much more complicated vocalizations/calls than chimps.
