Animal Weapons The Evolution of Battle

"Outstanding . . . Emlen's book on animal warfare reveals a world far more fascinating and intriguing than one we could summon with our imagination." -The Seattle Times

Every animal relies on a weapon of some kind-cats have claws, eagles have talons, even the dogs we keep as pets have a respectable set of teeth. In rare cases, we find species whose weapons have become stunningly outsized, some with tusks so massive that those who wield them look like they should collapse under the weight. In Animal Weapons, biologist Douglas Emlen pulls readers into the worlds of these remarkable beasts, trekking through rainforests and mountain passes to unravel the mysteries of their weapons. Along the way, Emlen shows that the essential biology of animal arms races applies to our own weapons, too. A story that begins with biology becomes the story of all weapons, as Emlen seeks to determine where this parallel leaves us today, in a world filled with the deadliest weapons of all time-nuclear, biological, and chemical weapons of mass destruction.

Douglas J. Emlen is the recipient of the Presidential Early Career Award in Science and Engineering from the Office of Science and Technology Policy at the White House, multiple research awards from the National Science Foundation, including their five-year CAREER award, and a Young Investigator Prize and the E. O. Wilson Naturalist Award from the American Society of Naturalists. His research has been featured in outlets including the New York Times and National Public Radio's Fresh Air. He is a professor at the University of Montana.

David J. Tuss is a graphic artist who specializes in blending technical accuracy with vivid, lifelike compositions. His work is also featured in textbooks, scientific articles, and technical biology papers. He lives in Helena, Montana, where he works as a wilderness ranger, natural science illustrator, and public school science and art teacher.
