BOOK REVIEW

Slithy Toves

Lizards are the real-world inspiration for the dragons of medieval fantasies, for reasons that will become obvious to readers of Lizards: Windows to the Evolution of Diversity, by Eric R. Pianka and Laurie J. Vitt (University of California Press, $45). This engaging, well-researched volume depicts an amazing variety of lacertilian beasts in its lavish illustrations and deftly examines their bizarre lifestyles and behaviors. Evolution has created some fanciful forms among these reptiles: Consider the African chameleon (Chamaeleo parsoni, far left), whose slothlike patience is matched with a wickedly quick tongue. Or the puny Amazonian leaf-litter gecko (Coleodactylus amazonicus), which weighs only half a gram when it is fully grown and is shown here carrying an egg that can be seen through the surface of its abdomen.—Michael Szpir

African Penguins"Penguins are 10 times older than humans and have been here for a very, very long time," said Daniel Ksepka, Ph.D., a North Carolina State University research assistant professor. Dr. Ksepka researches the evolution of penguins and how they came to inhabit the African continent.

Because penguins have been around for over 60 million years, their fossil record is extensive. Fossils that Dr. Ksepka and his colleagues have discovered provide clues about migration patterns and the diversity of penguin species.
