(Princeton University) How did civilization begin? Where did the division of labor come from? Do successful societies need strong leaders? Princeton and Rockefeller University researchers tackled those giant questions with some very small research subjects: genetically identical ants (Ooceraea biroi) that can live independently or in groups -- and have no queens. They found that simply increasing group size, even if it does not lead to division of labor, can benefit members of the group.
