Back in paleolithic times, people had to go hunt for food, following herds of bison or buffalo. They constantly had to move. Also, they had to gather plants and berries. This could be dangerous because people could get hurt while hunting or grab a poisonous plant or berry.
Now we dont need to hunt! We have all of our food growing right here at this farm.
We also learned how to domesticate animals! That way we have a more controlled food supply!
We are much safer now! Plus, we don't have to follow our food anymore!
