PASSAGE Edward O. Wilson’s Ants

Part 1

Careful of where he steps, carrying tweezers, vials notebooks and pencils ,(1) Edward O. Wilson has looked over, under, and into the world of ants. He has discovered (2) that the influence of ants’ behavior on their success as a species is as great as their number is vast. By thinking about and contemplating (3) ants, which are among the planet’s smaller creatures, Wilson has arrived at significant conclusions about their social organization and survival.

Wilson studies patterns of organization and behavior in whole ant colonies. [4] Because ants resume normal behavior quickly, ant colonies are easy to maintain and study in a laboratory. By observing ants in a few colonies in the field and in the lab, Wilson can describe an entire species.
