Molar size sequence in the great apes: gorilla, orangutan, and chimpanzee
P. E. Mahler
In ape dentitions the common molar size sequence is assumed to be MC
greater than M2 greater than M1. This sequence is held in contrast to the
assumed human sequence, M1 greater than M2 greater than M3. Using
mesiodistal, buccolingual, and cross-sectional area dimensions, this study
indicates that the molar size progression in all three great ape species
varies extensively from the assumed sequence.
