CHAPTER 1 OUTLINE ? From the Origins of Agriculture to the First River-Valley Civilizations I. History and Culture in the Ice Age A. Food Gathering and Stone Tools 1. The period known as the Stone Age lasted from 2 million years ago to 4,000 years ago. It is subdivided into the Paleolithic (Old Stone Age?to 10,000 years ago) and the Neolithic (New Stone Age). 2. The Paleolithic age is characterized by the production of stone tools that were used in scavenging meat from dead animals and later in hunting. Homo sapiens proved to be particularly good hunters and may have caused or helped to cause the extinction of mastodons and mammoths about 11,000 years ago.
