Book excerpt: Eye-opening, wise, and filled with triumphant and heartbreaking stories about the wolf population at Yellowstone (as well as some personal anecdotes about dogs), Carl Safina's Beyond Words: What Wolves and Dogs Think and Feel accessibly explores the mysteries of animal thought and behavior for young readers. Weaving decades of field research with exciting new discoveries about the brain, and complete with astonishing photos, Beyond Words offers an extraordinary look at what makes these animals different from us, but more importantly, what makes them similar, namely, their feelings of joy, grief, anger, and love. These similarities between human and nonhuman consciousness and empathy allow the reader to reexamine how we interact with animals as well as how we see our own place in the world.
