Who is Sapolsky's Baboons from A Primate's Memoir and what is their importance?

Sapolsky's baboons are a major feature of A Primate's Memoir though they mostly show up at the beginning of each part and their personalities are not explored as deeply as many of the human characters. But the baboons are nonetheless among the most important characters, despite their large number. The most notable baboons are mentioned separately but the most important feature of the baboon tribe is their hierarchical social structure and the way that it develops over time and in particular the way that male and female baboons of various rankings handle the stress associated with those rankings.
