Female chimpanzees prefer to play with objects and use them as tools more than male chimpanzees overall. Most often, female chimps are observed using them as play weapons.[1]

On one single occasion, some female chimps were observed carrying some logs and "slapping" them. This was interpreted as playing with dolls and then it was all over the news that female chimps play with dolls.[2]

Humans aren't the only primates with culture. Chimp behaviour varies significantly according to the culture they are in, just like human behaviour does.

Tangentially, I think I read somewhere once that there's more genetic variance between two random chimps from two chimp tribes in the same forest than between two random humans from opposite sides of the planet.
