Ants crawling on the ground. Caption: (Greene) One thing we're learning more and more about ant colonies

Harvester ants have a reputation for military precision, but one researcher in Colorado suggests they are more like a commune of free spirits. With no single ant in charge, harvester ants use chemical information and scent to the same effect that humans use visual information to determine their daily regimen. Wild Chronicles takes an up-close look at how altering an ant's chemical cues can change a colony's behavior and cause a mock battle. Segment of video from Wild Chronicles Segment.
