Here's a set of two pictures I got done by KingKevZilla: https://www.deviantart.com/kingkevzilla
Sometime ago I read that an earlier version of the first Planet of the Apes film's script involved a scene with evolved baboons, in the cornfield scene. I've been fascinated by that for awhile so I got KingKevZilla to draw what one of those baboons could have looked like, considering the limitations of makeup at the time. This first picture is of a baboon in what would've been the typical outfit for them, throughout the series.
