| The common scientific belief has been that army ants
| originated separately on several continents over millions
| of years. Now it is found there was one evolution. Using
| fossil data and the tools of a genetics detective, a
| Cornell University entomologist has discovered that
| these ants come from the same ancestor, because
| since the reign of the dinosaurs, about 100 million
| years ago, army ants in essence have not changed a
| bit.
