Abstract

"The paper's rough consensus attributes the SDoL to differential variance in food returns across male- and female-typical foraging domains, sourcing this primarily to Bird and Codding (2015) and Kelly's (2013) reframe of the classic 'hunting vs. gathering' axis as 'risky vs. non-risky foraging.' Indeed, the data show that males more often pursue large game and honey, resources that yield higher caloric returns but with high unpredictability, injury risk, and failure rates. Females, especially those with dependent young, more often target plant foods and small game that produce steadier, lower-variance returns. But variance-buffering is a proximate ecological account, not a life history account. It describes what the division of labor looks like without explaining why it is selectively stable, why it is age-structured within sexes, or why extensive male investment in offspring, rather than mate competition, is part of the human adaptive complex at all."
