Why Bonobos ?
The Bonobo (/b??no?bo?/ or /?b?n?bo?/), our closest living relatives, are highly tolerant and, in the wild, are capable of having affiliative interactions with strangers.
The research show that bonobos will forego their own food for the benefit of
interacting with a stranger.
Their prosociality is in part driven by unselfish motivation, because bonobos
will even help strangers acquire out-of-reach food when no desirable social interaction is possible.
