Yawning is a reflexive, instinctive behavior that appears to characterize all vertebrates. The cause and purpose of yawning are not yet fully understood. In addition to purely physiological causes, a communicative purpose plays an important role. The work includes large-format photographs of yawning humans and primates at Pongoland, at Leipzig Zoo, that is runned by the Wolfgang-Koehler Primaten Zentrum of the Max Planck Institute for Evolutionary Anthropology in Leipzig.
