The outer extremities of this envelope are limited by muscles, ligaments and the acticular disc of the TMJ. A few skeletons from other chimpanzee field sites conform to the dental and skeletal growth in Taï chimpanzees. So, common origin of man and chimpanzee is best shown by chromosome number and not by binocular vision, cranial capacity and dental formula. These differences can not only be associated with different populations across space, but also change over time so that the study of the characteristics of teeth could say which population one is dealing with, and at what point in that population's history they are.
