There is no documentation of the turning points that led to this change (like when people realized that seeds could be planted and how to enrich soils). Undoubtedly, the shift away from wild harvests was gradual, but about 12,000 years ago, the advent of agriculture led to a significant change in how people lived. Permanent settlements and farms were preferred over nomadic, hunter-gatherer lifestyles because they provided more consistent supplies of food and sustenance.
