Duck-wise, webbed feet is just a natural body formation. Webbed feet are formed within the process of a duck in an egg. Every specie of water-bird (i.e. goose, duck, swan....) has webbed feet! It's a natural thing! Humans cannot have webbed feet because there is no purpose for humans to HAVE webbed feet unless you swim a lot.
