In "Deep Time", Henry Gee, assistant editor of "Nature", shows us that everything we think we know about evolution is wrong. He also reveals the scientific proof of what came first - the chicken or the egg. It was the egg. For a long time, popular scientists have told us that by looking at a fossilized bone we could tell whether it belonged to our ancestors or not. This is not true. In "Deep Time", Henry Gee introduces a new way of thinking that has revolutionized the way that scientists are approaching the past - Cladistics. Cladistics ignores story-telling and authority and proposes a method based on shared characteristics, rather than ancestry and descent. As a result of using this new method, Henry Gee is able to show us the wealth of new ideas that is radically altering our notions of the past: dinosaurs with feathers; why fish developed fingers; and what it means to be human.
