Michael Covel speaks with Douglas Emlen on today’s podcast. Emlen is a professor at the University of Montana. He 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. He has also earned multiple research awards from the National Science Foundation, including their five-year CAREER award. Covel and Emlen discuss taking our lessons from animals; the connection with human and animal arms races; international hacking; comparing the fiddler crap to US and USSR bombers during the cold war; defining evolutionary biology; how an arms race can run its course via the example of the sabertooth tiger; the arms race in the trading world; how the cuttlefish has found its way around the “alpha” system; finding “workarounds” when the deck is stacked against you; war games and detente; why predictability in weapons is important; one-on-one showdowns; and the importance of being nimble. Emlen’s book, Animal Weapons: The Evolution of Battle, is available on Amazon.
