Response to: Who’s Tooth is it Anyway?
Julie Kazimiroff, dental professor at NYU College of Dentistry, attempts to cover the issue of cusp patterns with respect to relatedness among the hominoids. She starts off by posing a question regarding the 5 cusp (Y-5) molar pattern present in extant primates. To begin with, she emphasizes the importance of teeth to phylogenetics, as they are often times all that survives from an organism. DNA is brought into …showed first 75 words of 487 total…

…showed last 75 words of 487 total…stated all mammals developed their cusp patterns from this pattern. What this paper ends up doing is answering the question by stating that all cusp patterns originated with this group of reptiles. It basically provided an overview of the tritubercular theory and traced primate cusp patterns back to reptilian origins and eventually to the first time the familiar Y-5 pattern shows up, with the finding of an early hominoid, Dryopithecus ( according to this paper).
