Chapter 1: From Human Prehistory to the Early Civilizations Paleolithic (Old Stone) Age (2.5 million-12,000 BCE) Typified by the use of crude stone tools and hunting and gathering for subsistence Nature of the human species gradually changed with a more erect posture and growing brain capacity Now termed Homo erectus and it is thought that the species originated in eastern Africa about 500,00 to 750,000 years ago Developed and spread in Africa, then to Asia and Europe Newest human breed, Homo sapiens sapiens, originated 240,000 years ago, also in Africa Men hunted only 7 hours a day, 3 days a week while women worked harder to gather fruits and vegetables, but there was significant gender equality Population growth was slow

Name: Ambulocetus (Greek for "walking whale"); pronounced AM-byoo-low-SEE-tuss Habitat: Shores of central Asia Historical Epoch: Early Eocene (50 million years ago) Size and Weight: About 10 feet long and 500 pounds Diet: Fish and crustaceans Distinguishing Characteristics: Webbed feet; narrow snout About Ambulocetus: Ambulocetus dates from the era when the ancestors of modern whales were just dipping their toes into the water: this long, slender, otter-like mammal was built for an amphibious lifestyle, with webbed, padded feet and a narrow, crocodile-like snout. Oddly, an analysis of Ambulocetus' teeth shows that this prehistoric whale thrived in both fresh and salt water, a characteristic shared only with a single modern-day crocodile hailing from Australia.

The separation of the Paleolithic and Neolithic Ages mark a great divide in the lives and cultures of prehistoric peoples. Many aspects of everyday life were modified to suit a new standard of living. Society, Economy, and Technology were greatly affected by the "Agricultural Revolution" that spawned the Neolithic Age. The Paleolithic Age, Greek for "Old Stone", is the era of the emergence of modern man. During this age, man was a hunter-gatherer species. Due to the plentiful sources of animals and plants, man could simply follow the herds and their migratory patterns. With no proprietary knowledge, each nomadic band was egalitarian as there was no distinction for a social ladder.

Animal bones found near man. 3. Weapons, tools, utensils, and other artifacts. C. The earliest period of man?s history is the Old Stone Age (Paleolithic) 1. Manlike creature found in Africa (500,000 to 1,750,000 years ago) 2. Much like animals. 3.
