Social status motivates much of human behavior. However, status may have been a
relatively weak target of selection for much of human evolution if ancestral
foragers tended to be more egalitarian. We test the "egalitarianism hypothesis"
that status has a significantly smaller effect on reproductive success (RS) in
foragers compared with nonforagers. We also test between alternative male
reproductive strategies, in particular whether reproductive benefits of status
are due to lower offspring mortality (parental investment) or increased fertility
(mating effort). We performed a phylogenetic multilevel metaanalysis of 288
statistical associations between measures of male status (physical formidability,
hunting ability, material wealth, political influence) and RS (mating success,
wife quality, fertility, offspring mortality, and number of surviving offspring)
from 46 studies in 33 nonindustrial societies. We found a significant overall
effect of status on RS (r = 0.19), though this effect was significantly lower
than for nonhuman primates (r = 0.80). There was substantial variation due to
marriage system and measure of RS, in particular status associated with offspring
mortality only in polygynous societies (r = -0.08), and with wife quality only in
monogamous societies (r = 0.15). However, the effects of status on RS did not
differ significantly by status measure or subsistence type: foraging,
horticulture, pastoralism, and agriculture. These results suggest that traits
that facilitate status acquisition were not subject to substantially greater
selection with domestication of plants and animals, and are part of reproductive
strategies that enhance fertility more than offspring well-being.
