Millions of plants and animals live on Earth, but why do some species survive while others go extinct? A young readers guide to evolution with full-color cut-paper illustrations. There are millions of different kinds of plants and animals living on the earth, and millions more have lived here in the past. Where did they all come from? Why have some become extinct and others lived on? What lived on Earth before us, who is still with us, and what prompts evolutionary change? In this remarkable picture book, Steve Jenkins uses his signature eye-popping art to answer these questions and explore the fascinating history of life on earth and the awe-inspiring story of evolution.
