Is there a dominance hierarchy in humans?

In humans, dominance has been linked to heritable personality traits (Mehrabian, 1996); furthermore, superior status interacts with multiple neurotransmitter (Moskowitz et al., 2001) and neuroendocrine (Sapolsky, 2005) systems and can be automatically and efficiently inferred (Moors and De Houwer, 2005), indicating the …

Do humans form hierarchies?

Factors involved in determining dominance were size, sex and aggressiveness. Individual or role recognition or both may occur in this species.

What is the difference between a male and female chimpanzee?

Females also have a hierarchy within chimpanzee groups, led by the alpha female (though overall, an alpha male will almost always outrank an alpha female). The alpha female isn’t as likely to obtain rule through aggression and violence as a male would be, but instead through relationships and personality.
