Adjustments of Limb Mechanics in Cotton-top Tamarins to Moderate and Steep Support Orientations: Significance for the Understanding of Early Primate Evolution

Early primate evolution is connected to the efficient exploitation of the terminal branch habitat. Mammals that forage in this habitat constantly encounter flexible thin branches that bend under the weight of the animals and thus form steeply inclined and declined supports. This study was aimed to gain insight into how cotton-top tamarins – a previously proposed modern analogue for a hypothetical stage in early primate evolution with prehensile...
