Answer:
Based on the current theories and research on the sexual division of labor, four critical aspects of hunter‐gatherer socioecological led to the evolutionary origin of the SDL in humans:
(1) Long‐term dependency on high‐cost offspring
(2) Optimal dietary mix of mutually exclusive foods
(3) Efficient foraging based on specialized skill
(4) Sex‐differentiated comparative advantage in tasks.
Explanation:
These combined conditions are rare in nonhuman vertebrates but common to currently-existing populations of human foragers, which gives rise to a potential factor for the evolutionary divergence of social behaviors.
