Until a few years ago, the common idea among archiologists was [ that early human [ beings ] began [ to practice [ farming ] ] [ because they had no choice ] ].
Experts claimed [ that population growth led people [ to push some of their group members out of the most productive areas [ where it was easy [ to hunt and gather plenty of food from the wild ] ] ] ].
[ Living on the poorer edges of the rich environments ], [ according to the old [ thinking ] ], these people noticed [ that seeds of wild plants often began [ to grow [ where they had been thrown away or accidentally dropped ] ] ].
They then realized [ that [ planting crops intentionally in these poor areas ] provided a more plentiful and reliable source of food than [ hunting and collecting wild plants [ that could be eaten ] ] ].
