Negotiating sloping branches is a crucial aspect of arboreal life as animals must efficiently ascend and descend various supports. Climbing vertical supports likely played a major role in the acquisition of unique early primate specializations, but the functional and evolutionary interpretations of their locomotor, grasping, and visual adaptations, and their dependence on the arboreal environment remain unclear. Moreover, very little is known about descents in mammals. We investigated postural, kinematic, and grasping characteristics during ascents and descents on vertical supports in 22 small arboreal mammals, including 11 strepsirrhine and platyrrihine primates, 1 scandentian, 3 rodents, 3 carnivorans and 4 marsupials. We linked these behaviors to key morphological parameters to help reconstruct the paleoecology of extinct euarchontoglires. Vertical descents induced specific locomotor adjustments compared to ascents, notably increasing the proportion of asymmetrical gaits in all animals surveyed. Also, while all non-primate species preferentially employed headfirst descents regardless of their morphologies and body mass, primates exhibited specific upright strategies with strepsirrhines descending rump-first and platyrrhines descending in a side posture. Surprisingly, these upright vertical descents of primates were quite efficient compared to other mammals, allowing them to maintain higher speed and grasping postural diversity. Arboreal postural adaptations are highly influenced by the evolutionary history of mammals and result from a trade-off between body mass, limb proportions, grasping abilities and head size. We propose an ecological scenario of the sequence of acquisition of early primate grasping and locomotor specializations, constituting a hitherto unrecognized prerequisite for the origin of their encephalization.
