Abstract

Sleep is a fundamental biological process.1,2 The amount and quality of sleep individuals get can impact various aspects of human and non-human animal health,1 ultimately affecting fitness.3 For wild animals that sleep in groups, individuals may disturb one another’s sleep,4,5 but this aspect of soc...

We propose that this hierarchy effect is explained by higher-ranked baboons resting closer to more group members, which leads them to exert a greater influence on each other&#x2019;s nighttime behavior compared with lower-ranked individuals.
