A fascinating and well-grounded discussion of the evolution of eusocial behavior in certain species, including homo sapiens. The term “eusocial” refers to behaviors that are cooperative and mutually beneficial to individuals and to the hive or community as a whole. The central argument is that eusocial behavior has been highly successful from an evolutionary standpoint because it confers significant survivability and adaptability capabilities to a species. To put it simply, we do better as a species when we get along and take care of each other.
