A Study of Selected Physicomechanical and Histological Parameters of Hair Originating from Three Primate Species.

The aim of this study was to determine selected characteristics of hair originating from adult females of three primate species: lar gibbon, crested black macaque and common chimpanzee. The research material consisted of 300 hairs collected from the top of the head. The analysis included the length, diameter, strength, breaking load, elongation and cross-section area of the hairs, and the hair index. Additionally, the scale number per 1 mm of hair length was determined using scanning electron microscope images. Lar gibbon hairs were the thinnest and the longest, while common chimpanzee hairs were the thickest and the shortest, and concurrently the least resistant. Hairs from various primate species differ in terms of their morphological structure and histological features and thus can be used for differentiation and identification of species.
