<span>The neolithic revolution began when people discovered agriculture. Because of agriculture people could now farm instead of hunting and gathering. This allowed people to settle down and live in one place. This led to settlements and the development of group living. Since people after the neolithic rev began living in tighter more complex social situations this also led to better and more complicated forms of communication. The neolithic rev also eventually led to the development of governments because now that people were living in settlements they started dividing the work. They needed people to hunt, farm, cook, and do other things, and since not everyone could do the same thing they needed organization to decide who would do what. This led to higher forms of organization and ultimately to forms of government.</span><span />
