How has the Earth and life on it changed? Are birds and dinosaurs related? Why do looks count? `The Diversity of Species' explains how and why things on Earth have genetic and physical differences. Be amazed by the giants of the Galapagos and Komodo islands, study why the beaks of Charles Darwin's finches are important, and see what makes the chameleon's long, sticky tongue such a useful adaptation. There is even a mite that camouflages itself as an ant's leg, and a beetle with an exploding body! Life on Earth is constantly changing. It has been doing so for as long as we know and far before humans were here. Through the use of detailed case studies and scientific theories, the books in the 'Timeline: Life on Earth' series discuss how changes are studied, what the evidence reveals, and how such changes have had - and continue to have - an impact on Earth. - from Amzon
