        Ancient Farmers of the Amazon

        The coevolution of the leafcutter ant and the fungi on which it feeds is illustrated in this video segment from Evolution: Evolutionary Arms Race. Leafcutters have been "farming" this fungus for millions of years, feeding, fertilizing, weeding, and harvesting it. Learn how one graduate student's seemingly far-fetched idea led to the discovery that this symbiotic relationship involved at least two more, previously unaccounted for, species. Featured participants: Ted R. Schultz, Ulrich G. Mueller, and Cameron R. Currie.
