Morphological adaptations to climbing (a scansorial mode of quadrupedal, arboreal locomotion practised on twigs and small branches) are identified by relating anatomical details of limb bones to a sample of 6,136 instantaneous observational recordings on the positional behavior and support uses of 20 different free-ranging, adult red howlers. Our findings are used to infer the original habitat in which proto-red howlers may have acquired such adaptations and to hypothesize that climbing and its related anatomy are a primitive condition for anthropoids.
通过将四肢骨骼的解剖学细节与对20只不同的自由放养成年红吼猴的位置行为和支撑用途的6136次即时观察记录样本相关联，确定了对攀爬（一种在细枝和小树枝上进行的四足树栖运动的扫描模式）的形态学适应。我们的研究结果用于推断原始红吼猴可能获得此类适应的原始栖息地，并假设攀爬及其相关解剖结构是类人猿的原始条件。
