Penguins can fly - they just do it underwater...! They have adapted (in form and behaviour) to an environment that favours rapid swimming underwater, to catch their food in seas teeming with life, over flying in regions wrre there is little food available on land.
They can't fly because their wing are to small and their body's are to heavy.
