The incredible diversity of life on Earth--from microscopic single-celled organisms to giant redwoods and blue whales-is studied in more than 1,000 stunning photographs and illustrations. The introductory section, "A Planet Apart," guides the reader through the formation of the planet and the beginning of life, to evolution and animal and plant life today. The second section, "The Living World," introduces the kingdoms of life on the planet, from microscopic life, through plants to animals. The third and main section of the book, "Wildlife Habitats," takes a detailed look at the world's habitats, with "species features" that focus on animals and plants that are of particular interest, such as the vampire squid and the bristlecone pine.
