For long-term mating, however, the female is faced with the challenge of optimizing the combination of leadership and provider traits.Until now, scientists have not understood how humans evolved to prioritize pair-bonding over promiscuity, a critical development that laid the foundation for the modern family.Evolutionary biologists have struggled to explain how pair bonding and the nuclear family structure took root in humans, as primate groups typically establish dominance-driven hierarchies that restrict mating privileges to a few high-ranking males.…Using simple mathematical models, Sergey Gavrilets revealed that the most commonly proposed theories for human pair bonding are biologically unrealistic.Women also perceive very dominant males as more likely to cheat and divert resources away from the family.This may be of little or no concern to women who prioritize short-term mating.




On the other hand, women associate very masculine faces with negative traits such as coldness and dishonesty.

A new study proposes that it’s entirely attributable to female choice.

Women evolved to prefer cooperative, emotionally nurturing providers over physically dominant males: Pair bonding supplanted promiscuity in human evolution when faithful females began choosing good providers as mates, a study finds.



Men continually compete for dominance in social interactions with one another.
