Abstract
A morphometric study on the lower carnassial (M1) of Ursus spelaeus from three european populations has been carried out. Multivariate statistic methods have been used for this purpose. It has been proved that the variability caused by the sexual dimorphism interferes to an important degree in the suposed interpopulational differences. Once the intrapopulational variability has been put aside, significative differences between the analized populations have been found. These differences are well-marked in the degree of development of the cusps, and specially in the metaconid.
