Basques represent one of the few non-Indo-European populations in Europe. Ruhlen proposed a distant linguistic relationship between Basque and the Caucasian, Sino- Tibetan, and Na-Dene language families. Dentally, the first
language family is distinctly European while populations of the latter two exhibit Sinodonty. Some authors suggest Basques are the descendents of Upper Paleolithic peoples of Western Europe. Genetically, they have a high frequency of the Rh allele (r) and a low frequency of blood group B. Such differences set the Basques apart from their neighbors, but they still group with Europeans in world genetic analyses, suggesting a common origin but one with some time depth.
Little is known of Basque tooth morphology and size. To partially remedy this situation, observations were made on 29 crown traits in modern Basque and Spanish samples. We did not find any noteworthy differences in crown trait frequencies between Basques and either Spaniards or Europeans in general. Basques exhibit no incisor winging and low frequencies of shoveling, double shoveling, 3-cusped upper second molars, cusp 5, and cusp 7. Compared to Europeans, they exhibit fewer cusp forms of Carabelli’s trait and a higher frequency of deflecting wrinkle. The frequencies of four-cusped lower molars mirror almost exactly the frequencies of European populations. In a world-wide analysis, Basques cluster with Europeans although they separate at a higher level in the dendrogram. This does not, however, preclude a linkage between Basques and
Upper Paleolithic groups who also exhibit the dental pattern that sets Europeans apart from other world populations.
