The Uto-Aztecan premolar among North and South Amerindians: Geographic variation and genetics.

American journal of physical anthropology - 1 Dec 2010

Delgado-Burbano Miguel E, Scott G Richard, Turner Christy G

Abstract excerpt

The Uto-Aztecan premolar (UAP) is a dental polymorphism characterized by an exaggerated distobuccal rotation of the paracone in combination with the presence of a fossa at the intersection of the distal occlusal ridge and distal marginal ridge of upper first premolars. This trait is important because, unlike other dental variants, it has been found exclusively in Native American populations. However, the trait's...
