Arboreal mammals face unique challenges to locomotor stability. This is particularly true with respect to juveniles, who must navigate substrates similar to those traversed by adults, despite a reduced body size and neuromuscular immaturity.…
Locomotor features shared by arboreal marsupials and primates are frequently cited as a functional complex that evolved in the context of a "fine branch niche." Adaptation to a fine branch niche cannot be understood without considering that small and…
Recently proposed ancestral locomotor and morphological 'stages' leading to the evolution of primates have emphasized small body size, and a transition from a clawed non-grasping stage, to a clawed, grasping stage with clawless opposable hallux, to a…
