In In Search of Deep TIme, Henry Gee, Chief Science Writer at Nature, presents a painless and compelling introduction to cladistics, the approach to analyzing evolutionary relationships that revolutionized systematic biology. NCSE President Kevin Padian says, "This is a subversive book. Read it only if you want to know how scientists actually do their work, as opposed to the mythology of textbooks and documentaries. In it, you will discovery how and why the beloved Linnean system of taxonomy — the one that gave us classes and orders and families, oh my! — is being replaced by a wholly evolutionary way of looking at nature."
