The incidence of the different degrees of expression of Carabelli's trait in the deciduous and permanent dentitions was obtained on 651 skulls of three human prehistoric aboriginal samples from Gran Canaria (n = 329), Tenerife (n = 297) and La Gomera (n = 25) Islands. In the Gran Canaria sample, the total trait frequency for the permanent first molar was slightly greater in males, who also showed a higher degree of expression than females. However, in this sample, as well as in the Tenerife sample, the differences between the two sexes were not statistically significant. A high concordance regarding the presence and grade of expression of the trait was found between right and left sides, as well as between the deciduous and permanent dentitions. Marked differences were observed with respect to the incidence of the diverse degrees of expression of the trait between the Gran Canaria and Tenerife populations, whose cultural and anthropological differences are well established. The findings suggest that Carabelli's trait could be useful in establishing phylogenetic relationships between closely related populations.
从大加那利岛（n = 329）、特内里费岛（n = 297）和拉戈梅拉岛（n = 25）的三个史前人类原住民样本的651个头骨中，得出了乳牙列和恒牙列中不同程度卡氏特征表达的发生率。在大加那利岛样本中，恒牙第一磨牙的总特征频率在男性中略高，男性的特征表达程度也高于女性。然而，在该样本以及特内里费岛样本中，两性之间的差异无统计学意义。在该特征的存在和表达程度方面，左右两侧以及乳牙列和恒牙列之间存在高度一致性。在大加那利岛和特内里费岛人群之间，观察到该特征不同程度表达的发生率存在显著差异，这两个群体在文化和人类学方面的差异已得到充分证实。研究结果表明，卡氏特征可能有助于建立密切相关人群之间的系统发育关系。
