Explore how the violent and war-like behavior of chimps is similar to that of humans, and what that tells us about our evolutionary psychology.
The ability for primates to create and use tools is a key factor in their intelligence. The anticipation of felt and unfelt needs is also important for evolution towards higher intelligence in human ancestors.
The development of capital punishment has significantly changed the power dynamics in human societies, paving the way for a surplus of resources and raising questions on how human aggression might have adapted to these changes.
Humans needed to cooperate in order to fend off their territory and access new forms of food, leading to evolved biocultural morality based on moral emotions, norms, and reasoning. Chimp societies have higher incidents of violence but are less lethal compared to humans.
Women tend to be more cooperative in mixed-sex interactions, whereas men become more cooperative than women over repeated interactions in same-sex interactions. This may be due to women's tendency to engage in tit-for-tat behaviors and their emphasis on interpersonal loyalty.
