I think you're referring to the agricultural revolution, before which humans were hunter-gatherers. But even when people were moving around a lot, they didn't go very far, and I don't think it was for the same reasons.

> Hunter-gatherers tends to have much greater home ranges than pre-industrial sedentary farmers. It has been estimated that pre-industrial English people living in small townships would have had a home range of 900 hectares (9 km2), close to that predicted for an omnivorous mammal of their same body mass.
