Figure 7: Permanence and persistence of level 1 detail of skin over a long term. Persistence, but lack of permanence, of level 2 and 3 detail: (a,b) mated skin photos at ages 30 and 40, with magnified areas above and below the central photographs. In (b), the core area is somewhat more elongated; there are more ridge breaks below and to the left of the core; a dividing ridge has become an ending ridge (lower arrow); and there are variations in pore size and shape (upper arrows and circled area).Figure 8: Persistence, but lack of permanence, of level 2 detail of skin over a long term: (a, b) mated skin photos at ages 53and 61. The magnified areas are indicated by boxes. The arrow indicates where an ending ridge in (a) appears as a dot in (b). Figure 17: Lack of persistence of level 3 impressions over a short term: (a, b, c) mated ink rolled impressions collected in May, June, and August at age 26 show persistence of edge shape and ridge width (arrows); (d,e,f) mated ink rolled impressions collected in April, June, and August at age 31 exhibit variations in pore appearance (arrows); (g,h,i) mated impressions at age 27, where circled areas show variation in incipient ridges (April rolled ink, June inked flat, August inked flat, respectively).
