Borks live on a planet quite like our own Earth. They have shaggy yellow fur and long thin necks. But once they had short blue fur and 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 and all the things that happened to make them gradually look quite different, while still remaining Borks. And by the end of the story, the reader will have a very good notion of how Evolution by natural selection works.
