It's complicated: New research reveals more about the social networks of baboons and African monkeys‎

Like people, nonhuman primates live in groups that vary in size and shape depending on the species. Some primate groups are small and simple; others are large and more layered. Over the decades, primatologists have observed that baboons and other closely related monkeys, the African papionins, typically live in two types of social groups: single-level and multi-level societies.
