    • Abstract:
      In the 1954 movie 'The Naked Jungle,' Charlton Heston tries to save his coffee plantation from marauding army ants, which thrive throughout the world's tropics. Heston's character was probably too preoccupied to assume, as entomologists have, that the typical army ant traits--nomadism, foraging without scouting and wingless queens producing up to four million eggs a month--evolved numerous times in species around the globe. But Cornell University's Sean Brady, while at the University of California at Davis, compared the DNA, morphology and fossils of some 30 army ant species and came to an unanticipated conclusion: a common army ant ancestor first emerged on the supercontinent Gondwana about 100 million years ago and spread as the continents separated.
