Abstract:

Objective To determine the characteristics of dermatoglyphics ridge line direction of the palms of Taihang Macaca mulatta. Methods A total of 52 (37 females and 15 males) Taihang Macaca mulatta were examined in this study.The model of dermatoglyphics ridge direction of the palms was established, and compared with Macaca fuscata. Results At the population level, in interdigitalⅡ, the end of dermatoglyphics ridge lines were mainly in area 2, 5 and 6, and most frequently ended in area 6. In interdigital Ⅲ, dermatoglyphics ridge lines ended in area 6. In hypothenar 1, dermatoglyphics ridge lines were in 12/4/2 direction. There was no statistical difference when left and right palms(P>0.05) were compared. The two sides were symmetrical. Significant difference was detected between female and male Macaca mulatta in ridge line direction of palm angle 1(P<0.05), but not in that of palm angle 7(P>0.05) or Palm angle 8 (P>0.05). The dermatoglyphics ridge line direction of palms showed significant difference between Taihang Macaca mulatt a and Macaca fuscata (P<0.01). Conclusion Dermatoglyphics ridge line direction of the palms is one of the criteria characteristics to detect interspecific differences.
