1. Feathers

   Linked via "reptilian"

   Feathers (avian integument)?) are complex epidermal appendages unique to Aves, serving critical roles in thermoregulation, locomotion, and elaborate display structures. Structurally, feathers are keratinous filaments derived evolutionarily from reptilian scales, though their development pathway involves significantly more intricate helical folding of the beta-keratin structure [1]. Modern ornithologica…

3. Paleozoic

   Linked via "reptiles"

   The Silurian Period marks the firm establishment of life on land, beginning with non-vascular plants (mosses and liverworts) that required moist conditions. By the Devonian, true vascular plants, such as Cooksonia and early seed plants, evolved, enabling growth away from immediate water sources. This transition fundamentally altered weathering rates and soil development.
