Patterns sculpted by physics: Evolution as revealed by turtle scales In most vertebrates, skin appendages such as hair, feathers, or scales originate from placodes—small, specialized skin regions whose spatial organization is controlled by well-conserved genetic signals. Crocodiles are an exception: their head scales do not emerge from placodes but result from simple mechanical folding of the growing skin. /news/2025-06-patterns-sculpted-physics-evolution-revealed.html Evolution Molecular & Computational biology Tue, 10 Jun 2025 12:18:04 EDT news668776682 How do axolotls regenerate limbs and organs?
