Comparative phylogenetic methods are commonly used to investigate the evolution of primate adaptations including behaviour. Therefore it is crucial to establish robust phylogenies to directly incorporate the evolutionary history of a species into behavioural analyses. Furthermore, behaviour is not only influenced by genes but in turn can also shape the genetic structure of natural populations. Investigating this link is of great importance, because the alterations of genetic diversity induced by behavioural processes affect the material that evolution acts on. In this context gene flow between pop-ulations and species (hybridization) was found of particular importance in primate evolution.
