Among the Hadza, males are dominant over females and adults over sub-adults, but even in these two respects, the difference is slight compared to more complex societies. Some men are clearly much better hunters than others, but this does not result in a dominance hierarchy. Hunting reputation does seem to come closer than anything else to capturing what little status variation there is. There is also no clear hierarchy among adult females, although older women are afforded a little extra respect, as are older men.
