Once upon a time, a fish got tired of being wet and crawled onto land. The children of this fish stayed on land, their children grew better legs, learning to build nests on land, their children losing their scales. As more time went by, they spread over the land, separating into groups, some moving to two legs, some of those growing feathers, some of those moving their nests to the trees to keep them safer. Eventually, some of these – to the best of their ability – returned to the inland seas to dine upon the offspring of their distant ancestors.
There are more efficient ways to eat a fish, is all I’m saying.
