They were used in the same ways, and in precise specific contexts, such as play, grooming or competes. For example, some(prenominal) chimps and bonobos scream when threatened or attacked, a gesture that is luck by many other primates.
This suggests that these signals are an evolutionarily ancient nub of communication, and were probably used by the common ancestor that we divided up with both chimps and bonobos.
