Wild Dogs: Past & Present - Hardcover

Grade 5-9–This well-designed book explains how fossils and DNA are used to show the evolutionary lines from prehistoric canids to the dogs we live with today. In a relaxed tone, Halls conveys complex scientific information as she explains why some species die out while others survive and evolve. Common and scientific names are used, and an explanation of taxonomy as it relates to dogs is included. The author presents a wealth of detail through the accessible text; the informative captions, charts, sidebars; and the simple but clear maps. After a trip back 60 million years, Halls takes readers around the world providing photographs and facts about the wild dogs that live on each continent. She also addresses folklore and how various cultures have viewed these animals. The importance of conservation is emphasized, and an explanation of how the reintroduction of one wild species to a habitat can bring the return of others paints a clear picture of the interdependence among animal and plant species. The book ends, like it begins, with references to domesticated dogs, bringing science right into the lives of its readers. An extensive bibliography includes interviews, periodicals, and Web sites, as well as books. An attractive choice for reports or recreational reading.–Susan Oliver, Tampa-Hillsborough Public Library System, FL

Gr. 4-7. Dogs, from tree-dwelling prehistoric species to today's domestic bichons frises, are the subject of this comprehensive overview from veteran nonfiction author Halls. A fascinating survey of early dog descendants, which roamed the globe just after dinosaurs, is followed by a brief look at the dog family tree, including an introduction to taxonomic terms such as kingdom and phylum. Later spreads present today's canine species, grouped into continental habitats, beginning with North America. The mostly smooth text is supported by intriguing fact boxes that elaborate on various related subjects, such as Native American animal totems and the impact of wolves on Yellowstone Park's ecosystem. Numerous sharp color snapshots of the animals and an open design will draw plenty of browsers, including reluctant readers, and an extended bibliography, with a selection of Web resources, will lead researchers to more information. A natural choice for young animal lovers. Gillian Engberg
