If you ask "what did men evolve to do that women didn't?", math, politics, philosophy and engineering would be wrong answers, because for most of human history (and all preindustrial history) only a tiny fraction of people did those things, and in some societies they were women. By contrast, war is fundamentally human -- it has been with us for as long as records are available, and societies often conscripted large fractions of the population -- and historically it was almost entirely performed by men. The only more masculine activity than war is peeing while standing up.
