Then, about twelve thousand years ago and for reasons that remain imperfectly understood, some modern human populations adopted agriculture. This means they transitioned away from existing on merely the sustenance nature provided. Instead, they began actively promoting the growth and eventual transformation of crops, and later the domestication of animals, to provide themselves with the resources they needed. This shift in strategy inaugurated the Neolithic Age. The birth of agriculture triggered a host of additional changes in the way humans understood land, the way they organized socially, the amount and forms of wealth they could acquire, and even the religious traditions they practiced. Not everyone made the leap to farming, however. Plenty of hunter-gatherer societies avoided transitioning into a settled agricultural life, either because the new strategy wasn’t practicable in their environment or because for them the costs outweighed the benefits. Yet those groups that did become agriculturalists experienced a degree of population growth and labor specialization that ultimately allowed for the establishment of a number of sophisticated Neolithic settlements.
