Some sexually dimorphic traits that were unrelated to pubertal timing in our data may have been less relevant to our male ancestors’ mating success and hence to a fast LH strategy.).If these time-dependent effects of hormone exposure are present in humans, then pubertal timing may also partly explain individual differences in sexually differentiated human psychobehavioral traits (Zehr et al. Some evidence suggests that earlier puberty contributes to greater psychological sex typicality in humans.Because a faster male LH strategy emphasizes mating over parenting, earlier puberty may lead more generally to greater masculinization of traits that increase in sexual dimorphism at puberty and function in mating competition.In other words, we suggest that decreasing sensitivity to androgens represents a proximate mechanism that facilitates the development of mating-related adaptations in men with fast LH strategies. Consistent with our hypothesis, earlier recalled pubertal timing predicted greater adult male body mass index, facial dominance, biceps circumference, and, to a lesser degree, systemizing and mental rotation ability.
In some laboratory rodents, males’ brains and behavior become less sensitive to the organizing effects of androgens across the time window surrounding puberty.We have all type of personals, Christian singles, Catholic, Jewish singles, Atheists, Republicans, Democrats, pet lovers, cute Conway women, handsome Conway men, single parents, gay men, and lesbians.Free online dating in Conway for all ages and ethnicities, including seniors, White, Black women and Black men, Asian, Latino, Latina, and everyone else.Later puberty in human males has also been associated with less male-typical psychology and behavior, such as lower performance on mental rotation tasks and lower risk of substance abuse and delinquency.
Here, we propose that life history (LH) theory provides a useful theoretical framework for understanding such relationships between pubertal timing and phenotypic masculinization.Forget classified personals, speed dating, or other Bryant dating sites or chat rooms, you've found the best!
