Caste development and evolution in ants: it’s all about size.
Gene-Modified Ants Shed Light on How Societies Are Organized
Dr. Daniel Kronauer of Rockefeller University, a pasionate about ants, studies social evolution and behavior within complex societies. The sophisticated behavior, communication, and division of labor within ant colonies makes these social insects ideal model systems for this work.

“Female ants display a wide variety of morphological castes, including workers, soldiers, ergatoid (worker-like) queens and queens. Alternative caste development within a species arises from a variable array of genetic and environmental factors. Castes themselves are also variable across species and have been repeatedly gained and lost throughout the evolutionary history of ants. . . . “
