Borks live on a planet quite like our own Earth. They have shaggy yellow fur & long thin necks. But once they had short blue fur & almost no necks at all. How could this happen? Well, it didn`t come about all at once.. . Jonathan Emmett tells a delightful story in verse about the Borks & all the things that happened to make them gradually look quite different, while still remaining Borks. & by the end of the story, the reader will have a very good notion of how Evolution by natural selection works.
