What advantage did the neolithic people get from working together in communities

Before the Neolithic revolution, people would hunt and gather food; mostly working for themselves only.

After this, people turned to agriculture. By working together during agriculture, they could share their tasks and specialise (some people tending to food, some defending it) which lead to more food being produced and retained by the group (not stolen by others for example).

United states v.  nixon, 418  u.s.  683 (1974),  was  a landmark  united states supreme court case  that resulted in a unanimous  decision  against president richard  nixon, ordering him to deliver tape recordings  and  other subpoenaed materials to a  federal  district  court.
