The purpose of the study, by Jean-Marc Amé and José Halloy of the Free University of Brussels and colleagues, was not to research the potential ascendancy of cockroaches. The behavior is based on very simple interactions among individual cockroaches, Dr. Halloy said. Such simple decision-making models may apply to other gregarious species like sheep or fish, Dr. Halloy said.
