Abstract

We submit that wrinkling of molar crowns in Primates is a phenomenon of genetically controlled activity of the inner enamel epithelium that is grossly evident soon after initial calcification of the tooth occurs. The amount and pattern of this wrinkling are characteristic of the species before they are evident in the enamel surface itself.
