P.14 right column top paragraph: "The mature tissue (epidermis) is covered by a dead stratum corneum that is almost impermeable to gases, so that the respiratory role of the amphibian epidermis is lost (Fox, ’86 Warburg et al., ’96). A fundamental step toward the adaptation of the integument to the terrestrial environment was made in the mid Carboniferous, about 340 million years ago by the basal amniotes (or advanced anthracosaurians, primary source), from which reptiles, birds, and mammals evolved." |
