* ''The strongest associations with mating outcomes were seen in terms of body masculinity (r= .133, 95% CI: [0.091, 0.176]), voice pitch (r= .132, 95% CI: [0.061, 0.204]), and testosterone levels (r= .097, 95% CI: [0.070, 0.125]); moderation analyses showed that these three effects did not significantly differ from each other (p> .05).

Height and 2D:4D were also significant predictors of mating success, but showed significantly smaller effect sizes than body, voice or testosterone levels (height: r= .057, CI: [0.027, 0.087]; 2D:4D: r= .034, CI: [0.000, 0.069]). The relationship between facial masculinity and mating success was not significant (r= 0.080, 95% CI: [-0.003, 0.164]).'' | ||
* ''In the second set of analyses, we tested the hypothesis that masculine traits and testosterone levels positively predict reproductive success.

* ''As the only trait in our analysis that is consistently (and most strongly) correlated with fitness outcomes across populations, body masculinity is the only trait we can conclude appears to be under present selection in naturally fertile populations [...] Since traits such as strength and muscularity are associated with formidability, this finding lends support to the male-male competition hypothesis.'' | * ''As the only trait in our analysis that is consistently (and most strongly) correlated with fitness outcomes across populations, body masculinity is the only trait we can conclude appears to be under present selection in naturally fertile populations [...] Since traits such as strength and muscularity are associated with formidability, this finding lends support to the male-male competition hypothesis.'' | ||
