State
Primates share traits supporting an arboreal ancestry: forward-facing eyes for depth perception, grasping hands, and, in most lineages, nails rather than claws.
Show
A primate's forward-facing eyes give overlapping visual fields, supporting the depth perception useful for judging distances between branches.
Watch for
These traits reflect an arboreal history — not every living primate species spends most of its time in trees today.
