In contrast, homodont or isodont dentition refers to a set of teeth that possess the same tooth morphology. In invertebrates, the term heterodont refers to a condition where teeth of differing sizes occur in the hinge plate, a part of the Bivalvia .
Cast of a human upper jaw showing incisors, canines, premolars, and two of the three possible sets of molars. Dentition pertains to the development of teeth and their arrangement in the mouth . In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. [ 1 ]
Thus, comparisons between chimpanzees and Homo sapiens could be used to identify major differences. Major characterizing features of Pan troglodytes dental morphology include the presence of peripherally located cusps, thin enamel, and strong facial prognathism.
A horse can have between zero and four canine teeth, also known as tusks (tushes), with a clear prevalence towards male horses (stallions and geldings) who normally have a full set of four. Fewer than 28% of female horses have any canine teeth. Those that do normally only have one or two, and these may be only partially erupted.
The palatal teeth are broad and fit tightly together, an adaptation to consuming fibrous plants. This variation in tooth shape, known as a heterodont dentition, is common in mammals. While most other Permian therapsids had homodont dentitions (teeth of the same shape), Tiarajudens is one of the earliest therapsids to have a heterodont dentition ...

The difference between now and the past is that such a decision is available not simply to 16-to-18-year-old high school recruits, who are also easily swayed by things like jersey colors ...
Sexual dimorphism describes the morphological, physiological, and behavioral differences between males and females of the same species. Most primates are sexually dimorphic for different biological characteristics, such as body size, canine tooth size, craniofacial structure, skeletal dimensions, pelage color and markings, and vocalization.
