دانلود کتاب Prehistory (DK ONLINE)

DK, the best reference publisher, meets Google(tm), the world's best search engine in a comprehensive and authoritative series that's online, and sets the benchmark for reference. Providing complete and visually arresting reference at an entirely new level, e-links lead you to online information you can't get in a book: live and archival footage; sound buttons; interactive polls, quizzes, and games; links to organizations and the latest research. Each e-link tells you which keyword to use-then Google(tm) / DK take you straight to the safe, appropriate, and accurate online information. Behemoth vegetarians, scrappy carnivores, huge leafy plants, and violent storms all played a role in making Earth what it is today. Learn about the early life of our planet and the plants and animals that thrived here.
