Describe the major developments of early human and social evolution. Throughout, discuss tool manufacturing, language development, agriculture, social behavior, and population growth.

The Neolithic Era brought forth greater specialization. People began to make chisels, drills, and saws to address specific needs and also polished stones to create sharper and more defined points (Holt, Rinehart, & Wilson, n.d.: 2).

Humans began to domesticate animals and engage in selective breeding. With the end of the Ice Age, new plants became available and were cultivated to provide a more stable food source than hunting and gathering. Humans began to domesticate plants as well.
