Certainly it is. An ape in a tree is much more mobile than a leopard. The
accessible space to a large carnivore with convergent pes and manus is
limited to the tops of some large branches, while a smaller ape with
grasping pes and manus could reach at least twice (prabably ten times) as
much volume.
