Hand2: Positional code that allows axolotls to regrow limbs found
Living in a murky lake around Mexico City, surrounded by aggressive and cannibalistic neighbors, the axolotl lives at constant risk of losing a limb to a neighbor's nibble. Fortunately, lost limbs regrow and are functional in as few as eight weeks. To achieve this feat, the regrowing body parts must "know" their position within the axolotl body to regenerate the right structure for a specific location.
