You Can Spot More Aggressive Men By Their Faces
According to Canadian scientists, men with wider faces are more aggressive. Men have wider faces than women, and the differences start emerge at puberty when testosterone levels increases. Testosterone is tied with aggression, which led to a link between aggression and wide faces. But the face width is not linked with aggression in women. The size of the faces have been shaped by evolution to signal aggressiveness to others.
Female Domination
Male domination is common among primates including monkeys. But when the number of males increases, females become more strong and dominant. According to researchers, this new finding could true with humans. Male primates are usually larger than females, and it is easier for them to be stronger. But there are times where females dominate, for instance lemurs in Madagascar and macaques.
Findings support that these females are not larger than males, but they dominate due to odds. Chances of wining a fight by a female increases when male aggression is more intense and more males are defeated by other males. Therefore high-ranking females may be victorious over these losers. When females win a fight by chance, they grow more confident and win more fights, and eventually they dominate.
