The division of labor creates specialized behavioral groups within an animal society, sometimes called castes. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform behaviors characteristic of individuals in another caste.
Charles Darwin considered the evolution of eusociality a major problem for his theory of natural selection.In The Origin of Species, he described the existence of sterile worker castes in the social insects as "the one special difficulty, which at first appeared to me insuperable and actually fatal to my whole theory".
An animal that exhibits a high degree of sociality is called a social animal. The highest degree of sociality recognized by sociobiologists is eusociality . A eusocial taxon is one that exhibits overlapping adult generations , reproductive division of labor , cooperative care of young, and—in the most refined cases—a biological caste system .

The mediator for the social recognition systems included a blend of hydrocarbons that each individual within a colony carried as a way to recognize others from within the same colony. [1] The individuality of the sole insect and the cohesion of the colony are very similar in the ways that they approach recognition and solve conflicts. [3]
Some polymorphic ants can have workers who look morphologically very different from each other, with specific jobs and behaviours. [ 1 ] [ 3 ] Examples of these polymorphisms can be seen in the big-headed ants Pheidole dentata, where the different castes of workers (majors with large heads and minors with regular sized heads) increase colony ...
For many animal societies, an individual's position in the dominance hierarchy corresponds with their opportunities to reproduce. [6] In hierarchically social animals, dominant individuals may exert control over others. For example, in a herd of feral goats it is a large male that is dominant and maintains discipline and coherence of the flock.
