The vicuña is considered more delicate and gracile than the guanaco and smaller. A key distinguishing element of morphology is the better-developed incisor roots for the guanaco. [8] The vicuña's long, woolly coat is tawny brown on the back, whereas the hair on the throat and chest is white and quite long.
Primate sociality is an area of primatology that aims to study the interactions between three main elements of a primate social network: the social organisation, the social structure and the mating system.

[15] Within sociobiology, a social behavior is first explained as a sociobiological hypothesis by finding an evolutionarily stable strategy that matches the observed behavior. Stability of a strategy can be difficult to ...
