The Super Powers of Superman
Superman derives his super powers from the yellow sun. His super powers are the product of Krypton physiology adapted to a yellow sun under the DC Earth biosphere. His alien physiology grants him a super-dense cellular structure and yellow sun radiation energy absorption. His super powers are a metabolization of adaptation to a foreign less advanced world. Krypton was held back in its biological evolution by the red sun god Rao, an evolution that the yellow sun grants to Superman.
