  1. All measurements in cm except Total number of teeth (TEE) and Number of teeth in 10 cm2 (TEE10) these amount. Different capital letters in bold among populations indicate significant differences according to ANOVA and Tukey test (*p ≤ 0.05, (**p ≤ 0.01). The last columns show eigenvectors of the first (PC1) and second (PC2) principal components according to PCA, and the Discriminant Functions 1 and 2.
