Hierarchy steepness and social inequality in non-human primates
Texte intégral
1Non-human primate species, similarly to human societies, display a wide variation in hierarchy steepness. I will present data showing that dominant individuals tend to have greater fitness than subordinates (i.e., greater infant survival). However, a comparative analysis on 27 primate species showed that hierarchy steepness is not significantly correlated with the extent to which individual dominance affects the acquisition of fitness-related benefits. This finding may be due to the counter-strategies employed by subordinates to gain access to fitness-related resources. In the final part of my talk, I will discuss potential differences and similarities between the formation and maintenance of a social hierarchy in non-human primates and in human societies.
