This is quite a vague question since there aren’t any answer choices and one could go on and on talking about this, but I will give the shortest and simplest answer possible. :)
Basically... agriculture and specialization made it possible for humans to finally settle in one place and make a living. They were finally able to create a civilization, start a family, and overall... stop having such a nomadic (living the life of a nomad; wandering) lifestyle.
Hope this helped! :)
