 One of the most important aspects of the genus' social evolution and adaptation is the manner in which their social organization has been shaped by environmental pressures.This is particularly true of the species "Cephalotes rohweri", in which an entire soldier class has evolved as a result of highly specialized nest cavity availability.Because ants within "Cephalotes" use multiple carved nesting cavities found in the trees upon which they live, a cohort of morphologically specialized soldiers has evolved to defend these nesting cavities.
