Interpreting the Map Have students locate the places where human migrations began. Point out that those places are near the equator, hilly, and close to rivers or large bodies of water. Ask how such geographic features might have helped early humans thrive. (They offer a consistently warm climate, abundant food and water year-round, and resources for making tools.) Ask students to discuss how the climate of human sites along the northern migra- tion routes might have differed from that of equatorial Africa. How might people have had to alter their environment to survive? (They might have cut down forests to build fires and create perma- nent shelters, hunted animals for food and clothing, and built areas to store food during the winter.)

Have them imag- ine how much change the invention of A dagger and its sheath the axe would have made in the lives of early peoples. EXAMINING the ISSUES
• What did early humans need to do to survive? • What physical actions would these tools help humans do? As a class, discuss these questions. In your discussion, think about recent tools and inventions that have changed people’s lives. As you read about the ancestors of present-day humans, notice how early toolmakers applied their creativity and problem-solving skills.

CHAPTER 1 • SECTION 1 of wood and animal skins. Animal bones found with Neanderthal fossils indicate the ability of Neanderthals to hunt in subarctic regions of Europe. To cut up and skin their prey, they fashioned stone blades, scrapers, and other tools. The Neanderthals survived Comparing for some 170,000 years and then mysteriously vanished about 30,000 years ago. How were Neanderthals simi- Cro-Magnons Emerge About 40,000 years ago, a group of prehistoric humans lar to people today? called Cro-Magnons appeared. Their skeletal remains show that they are identical C. Answer to modern humans. The remains also indicate that they were probably strong and Neanderthals held generally about five-and-one-half feet tall. Cro-Magnons migrated from North religious beliefs and Africa to Europe and Asia. performed rituals Cro-Magnons made many new tools with specialized uses. Unlike such as funerals. Neanderthals, they planned their hunts. They studied animals’ habits and stalked their prey. Evidently, Cro-Magnons’ superior hunting strategies allowed them to survive more easily. This may have caused Cro-Magnon populations to grow at a slightly faster rate and eventually replace the Neanderthals. Cro-Magnons’ advanced skill in spoken language may also have helped them to plan more diffi- cult projects. This cooperation perhaps gave them an edge over the Neanderthals.

More About . . .
African Art Many of the rock paintings in Algeria were completed in prehistoric times, when large animals, such as the elephants, rhinoceroses, and giraffes depicted in the paintings, roamed what is now the Sahara. The region was much wetter then than it is today. Abundant lakes, streams, forests, and grasslands enabled such animals—as well as the people who painted them—to thrive there.
