Partner choice and the evolution of human cooperation: Evidence from hunter-gatherers
Humans cooperate to an unparalleled scope and degree in the animal kingdom. How did this propensity to cooperate with strangers evolve?

I will present data from Hadza hunter-gatherers that cast doubt on the partner choice hypothesis.
