Making Space for Permanent Molars in Growing Baboon (Papio anubis)
and Great Ape (Pan paniscus and P. troglodytes) Mandibles: Possible Ontogenetic Strategies and Solutions
(a) Total mandible length (MANDL) grew at similar rates in Papio and Pan troglodytes, but more slowly and to shorter adult lengths in Pan paniscus. (b) Posterior corpus length (POSTL), where the permanent molars develop, grew to the longest adult lengths at the fastest rates in Papio. The inverse was seen in P. paniscus. (c) In all three species, POSTL grew to about half the length of MANDL. Red squares, Pan paniscus; teal triangles, Pan troglodytes; blue diamonds, Papio anubis.
