The Natufians differed from their predecessors in many ways – most significantly, in their move toward agriculture. A. The Natufians used tools to collect and process food, but their lack of containers suggests that they rarely had excess food to store. B. The increase in salt in the Natufians' diet suggests that meat was becoming harder to find, perhaps because of climate change. C. The Natufians engaged in trade and lived in large camps in which they sometimes built permanent structures. D. Natufian culture developed somewhat differently in different regions, in part because of differences in the types and amount of food available from place to place. E. Although their diet included meat from hunting, extensive evidence suggests that the Natufians consumed a lot of cereals and may even have been cultivating them. F. Natufian art, personal ornamentation, and burial sites suggest cultural changes involving an increasing sense of ethnic identity and perhaps an ancestor cult.
