Sigrid Metz-Göckel,Marion Kamphanson a comparative basis by Lucas and Stettenheim (1972). Brush (1974, 1975, 1980) and Brush and Wyld (1982) have used the biochemical composition of feathers in comparative and evolutionary studies of several bird species. In general, the body of most birds appears covered by feathers with obvious na归功于 发表于 2025-3-27 17:14:26

Pigmentation is related to the number, size, type, and distribution pattern of melanin-containing cytoplasmic particles, i.e. melanosomes (Seiji et al. 1961; Jimdragon 发表于 2025-3-28 11:04:44

The second of the epidermal appendages to differentiate, following only the hair anlagen during ontogeny (Serri and Huber 1963; Bell 1971 b; Breathnach 1971), they soon connect directly by means of ducts with their associated hair follicles, thus forming pilosebaceous units.
