Answer:
Humans developed multiple uses for their resources.
Explanation:
During the Neolithic or Polished Stone Age there were major changes in climate and vegetation and in the use of natural resources. The European continent now has milder temperatures and we observe the formation of the Sahara Desert in Africa.
Hunting and gathering became increasingly difficult options, so people began to find new uses for available resources, agriculture, and the consequent process of sedentary man settling down gradually. In addition, animal domestication became a common practice among the human groups that formed in this period. The stability obtained by these new techniques of mastery of nature and animals also made possible the formation of large population clusters.
