Extreme Weapons: A Natural History
biology, war, weapons, beetles, battleships
Every animal has a weapon of one sort or another, but the overwhelming majority of weapons stay small. Yet, sprinkled through the tree of life are species where weapons become extreme. Occasionally, human-manufactured weapons also evolve to extremes. Emlen reveals that the same critical conditions trigger arms races in both cases, and the most crucial prerequisite is duels. A journey that begins with biology becomes the story of all weapons, as Emlen discusses beetles and battleships, crabs and the Cold War.
