Abstract/OtherAbstract:
This is the first report of foot preference during locomotion in Old World monkeys. Foot preferences during the quadrupedal walking action and the bipedal shifting action of a naturalistic group of Sichuan snub-nosed monkeys (Rhinopithecus roxellana) in Zhouzhi National Nature Reserve in the Qinling Mountains of China were investigated. Twelve of 21 individuals tested on quadrupedal action and all 21 individuals tested on bipedal action exhibited a significant foot preference. Both significant right- and left-footed preferences were observed; sex affected neither direction nor strength of foot preference in both actions. The finding that 61.90% of focal R. roxellana showed a right-foot preference, both in quadrupedal action based on the footed index and in bipedal action based on the z-score, is in partial agreement with the postural origin hypothesis on footedness. Foot preference was significantly stronger in bipedal action than in quadrupedal action, supporting the view that posture could be a crucial factor influencing foot preference as well as hand preference in this species.
