Eusociality, an Uncommon card

The card carries these facts from its Wikipedia article.

• It is defined by the following characteristics: cooperative brood care, overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups.
• 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.
