Answer:
allowing them to perform jobs other than looking for food
Step-by-step explanation:
The development of farming changed the lives of some ancient Americans by allowing them to perform jobs other than looking for food. This is because the development of agriculture about 12,000 years ago changed the way humans lived. They switched from nomadic hunter-gatherer lifestyles to permanent settlements and farming. Since there was no need for all residents to devote themselves full time to producing food, specialization within society was made possible.
