Lesson 1: Hunter-Gatherers

Paleolithic people (2.5 million years ago to 8000 B.C.) were nomads who traveled in bands of 20-30 members to find food. Men hunted large animals while women gathered plants and cared for children. Their survival depended on knowing which animals to hunt and plants to eat. They adapted to different environments by creating appropriate clothing and shelters from available materials.

Paleolithic people created the first tools from flint, which could be struck to create sharp edges for cutting. Over time, they developed more complex tools like spears, bows and arrows, harpoons, and bone needles. These technological advances helped them hunt, prepare food, make clothing, and build shelters, significantly improving their chances of survival.

The discovery of fire transformed Paleolithic life by providing warmth, light, and protection from animals. People learned to start fires through friction or by striking stones. Fire allowed them to cook food (making it tastier and easier to digest), preserve meat through smoking, and gather socially. During the Ice Age, fire was crucial for survival in cold environments.

Paleolithic people developed spoken language to share information, work together, and express thoughts and feelings. They also created art, particularly cave paintings found worldwide. Using pigments made from crushed rocks mixed with animal fat, they painted animals on cave walls. These paintings may have been created for religious purposes, to record history, or simply for enjoyment.

During the most recent Ice Age (100,000-8000 B.C.), humans adapted to extreme cold by enriching their diets with fat, building sturdier shelters, and making warm clothing from animal furs. As ice sheets grew, sea levels dropped, creating land bridges between continents. This allowed people to migrate from Asia to North America, where they moved southward to settle in different regions.
