  Humans, along with their closest relatives bonobos and chimpanzees, are highly social animals. This biological context suggests that the underlying sociability required for the formation of societies is hardwired into human nature. Human society features high degrees of cooperation, and differs in important ways from groups of chimps and bonobos, including the parental role of males, the use of language to communicate, the specialization of labor, and the tendency to build "nests" (multigenerational camps, town, or cities).
  
  Some biologists, including entomologist E.O. Wilson, categorize humans as eusocial, placing humans with ants in the highest level of sociability on the spectrum of animal ethology, although others disagree. Social group living may have evolved in humans due to group selection in physical environments that made survival difficult.
