This might reflect limitations in the ability of this method to detect diet-related differences, but is also consistent with a lack of differences in functionally relevant aspects of occlusal morphology among chimpanzee subspecies. Although differences were noted between wear stages within subspecies in surface slope, relief, and angularity, none were found to distinguish the subspecies from one another in these attributes. High-resolution casts from museum collections were examined by laser scanning, and resulting data were analyzed using GIS algorithms and a two-factor ANOVA model. skull of a medieval man, the jaw of an orangutan, and chimpanzee teeth. How do the size and shape of human canines compare with chimp. They are distributed from about 10 degrees N to 8 degrees S. How many teeth are found in each species maxilla Pan troglodytes: 16 Homo sapiens: 16. The diagram at the right provides a basic vocabulary used in. Chimpanzees (Pan troglodytes) inhabit the tropical forests of central Africa. On the extreme left, there is a label that says Common Ancestor. Also, earliest proto-human forms, like other primates, had far larger canine teeth than we have. The text box below it shows the set of derived shared characteristics for the branching tree. This study uses dental topographic analyses shown to reflect diet-related differences in occlusal morphology among primate species, to assess within-species variation among chimpanzee subspecies. BRAINLIESTThe diagram below shows the branching tree diagram for humans. And in fact, observations to date of the diets of chimpanzees have not revealed consistent differences among subspecies. Chimpanzee subspecies have been reported to exhibit differences in molar dimensions and nonmetric traits, but these have not been related to differences in their diets. The nearly identical teeth do not only generate familiar smiles in our primate cousin. Molar tooth morphology is generally said to reflect a compromise between phylogenetic and functional influences. The dental structure of humans and chimpanzees is strikingly similar.
