Research on wild Assamese macaques

We aim to understand how the striking diversity in primate social structure evolved. What drives the variation in social relationships among and within species, populations and groups? Why are some species, populations, groups or individuals aggressive, individualistic and unforgiving, while others are friendly, peaceful and cooperative – and why do find on top of this variation across time or depending on the identity of the interaction partner?
