What is the main conflict in A Primate's Memoir by Robert M. Sapolsky?

A Primate's Memoir combines the autobiography of Robert M. Sapolsky's journey to his doctorate in Neuroendocrinology with the story of one baboon troop. Sapolsky shares a frank look at the life of a researcher in the field of Africa as he describes the life of his baboon troop and the outside factors weighing on them from environment, Masai tribes, local government and finally bovine tuberculosis.
