Out of the Blue: How Animals Evolved from Prehistoric Seas

Description: "Clear and inviting nonfiction prose, vetted by scientists--together with lively illustrations and a time line--narrate how life on Earth emerged "out of the blue." Learn how and why creatures began to emerge from the deep--from the Cambrian Explosion to crustaceans, mollusks to fishes, giant reptiles to the rise of mammals--and how they compare to the animals we know today, in a lively and accessible outing into the prehistoric past that boils a complex subject down to its lyrical essence."--Publisher's description.

Review Quotes: Shreeve anchors this chronicle of the development of life on Earth with an opening question: Among hippos, dolphins, and sharks, which two are the closest relatives?. . . Increasingly complex creatures fill subsequent pages. Along the bottom margin runs a general time framework beginning with the Archaeon Eon and moving quickly through time. . . Preston-Gannon's cheerful, colorful illustrations show an astonishing variety of creatures, all with circular, white-outlined black eyes. The total package is simple and effective.

--School Library Journal (starred review)

Shreeve adeptly communicates high-level scientific concepts in just a few paragraphs per page as she highlights key events in the transition from sea to land. . . Preston-Gannon's use of color in the friendly illustrations skillfully represents the climatic conditions in each major era: bright, multicolored spreads of tropical seas filled with animals represent periods of species growth and are interspersed with less hospitable, barren landscapes.
--The Horn Book

This short book guides the reader from the beginnings of life eons ago through to the present day, beginning with an Earth devoid of life and following water-dwelling, single-celled creatures that develop and change as they move "out of the blue" and onto land. The text explains the adaptations that were necessary for animals to live out of the water, as well as how some animals survived (and how others didn't) during the several extinction events that Earth has suffered.
