At one primate center when caretakers arrive with food the
chimpanzees start to hoot and holler and jump around in
what appears to be a dance. This can be seen as as a celebration
to reaffirm the group's hierarchy between the dominant and
submissive members. When the food is laid out "negotiations
over food distribution then begin, as chimps who want food
approach those with enough to share. Food changes hands
about half the time; the rest of the requests get rejected.
Chimps most often get food from individuals whom they have
groomed that day". Sometimes fights occur, but that is rare.
Usually fights break out when someone doesn't give up food
after receiving grooming or takes food without performing
some kind of service. After a fight, chimpanzees usually
hug, kiss, or make up in some way. Chimps are very much
like us.
Chimpanzees belong to large groups or communities. But,
they also go in small groups for much of the time looking
for food and socializing. Chimps can show much affection
but can also be very aggressive when necessary. Most chimpanzees
have a nervous temperament, which is also the case with
human beings.
