Baboons form orderly queues, researchers say

Baboons form an orderly queue for access to a patch of food, waiting until a dominant male has investigated it, research has shown.
The order in which the animals queue is probably based on their position in the social hierarchy, according to lead researcher Dr Alecia Carter from the University of Cambridge.
Baboons live in complex societies, with close bonds that are strengthened by activities like play and grooming. Scientists want to understand these primate societies in order to understand the evolution of our own.
