ABSTRACT Behavioral contagion is widespread in primates, with yawn contagion (YC) being a well‐known example. Often associated with ingroup dynamics and synchronization, the possible functions and evolutionary pathways of YC remain subjects of active debate. Among nonhuman animals, geladas (Theropit...
