It ain't easy bein' top dog. Or, for that matter, top monkey. Sure your underlings would pay to gaze at your pictures, but being alpha baboons come at a high price:
A new study, "Life at the Top: Rank and Stress in Wild Male Baboons," published in the July 15 issue of the journal Science found that in wild baboon populations, the highest-ranking, or alpha, males have higher stress-hormone levels than the highly ranked males below them, known as beta males -- even during periods of stability. The findings have implications in the study of social hierarchies and of the impact of social dominance on health and well-being, a subject of interest among researchers who study human and other animal populations.
