Bellringer • What are the three main stages of human development in prehistory? • What are you and all humans today known as? • You may use your notes. Chapter 2 – Hominids & Early Humans Social Studies 7 Fall 2013 Human Ancestors- Australopithecus • Name means “Southern Ape” • Appeared in Africa about 4-5 million years ago • Stood upright and walked on two legs • Brain was about 1/3 the size of modern humans. • Another ancestor of humans is called a “hominid.” Homo habilis • Name means “handy man” • Appeared in Africa about 3 million years ago • It is believed that they evolved from Australopithecus. • Used early stone tools for chopping and scraping • Brain was about half the size of modern humans KNM ER 1813 is a relatively complete cranium which dates to 1.9 million years old, discovered at Koobi Fora, Kenya by Ajit Sharma in 1973. Homo erectus • Name means “upright man” • Appeared in Africa about 1.5 million years ago • Used early stone tools like the hand ax • Learned to control fire • Migrated out of Africa into Europe and Asia Reconstruction of a specimen from Tautavel, France Homo sapiens • Name means “wise man” • Appeared in Africa about 200,000 years ago • Migrated all over the world • Learned to create fire and use a wide variety of tools • Developed language • Oh yeah… you are one. Tools • Early humans developed tools • Used to process food • Cutting, chopping, scraping • Used on roots, bones, or meat Later tools • Over time, tools got better • Added wooden handles • Spears were developed • Allowed for hunters to kill larger animals from a distance Skills of early humans • HUNTING done together to bring down large animals • GATHERING plants, seeds, fruits, and nuts • FIRE to cook food, provide warmth • TOOLS used for hunting and preparing food Language • Makes hunting in groups easier • Forms relationships • Resolves issues like distributing food • Art (cave paintings) used as language? • Tell about hunting or create religion? Hunter-gatherer societies • MEN = Hunters. They traveled together in packs. Sometimes chased large animals over cliffs. • WOMEN = Gatherers. Collected plants, fruits, etc. to eat. Stayed near the camp and took care of the children. • PEOPLE = MOVED! They went wherever the herds went so they could eat and survive! Ice Ages • Began about 1.6 million years ago and ended just about 100,000 years ago • Huge sheets of ice covered much of the earth’s land—sea levels were lower. • People had to MIGRATE (move) to new places. Pattern of Human Migration • • • • Start in Africa To Europe, Asia To Australia To North America • To South America Stone Ages • Paleolithic Era (Old Stone Age) • Mesolithic Era (Middle Stone Age) • Neolithic Era (New Stone Age) Three Stone Ages • Paleolithic Era (Old Stone Age) = Early humans… lasted until about 10,000 years ago. • Hunter-gatherer societies • Old stone tools • Learned to attach wooden handles to tools Three Stone Ages • Mesolithic Era (Middle Stone Age) = 10,000 to 5,000 years ago in some places • People found new uses for bone and stone as tools • Tools became smaller and more complex (hooks, fishing spears, bow and arrows) • Developed canoes from logs, made pottery, “domesticated” animals (aka PETS) Three Stone Ages • Neolithic Era (New Stone Age) = Occurred in parts of the world 10,000 (early in Southwest Asia) to 5,000 years ago • Polishing stones to make saws and drills • Learned to make fire • Ended when people began making tools out of metal and were able to PRODUCE their own food (Neolithic Revolution) People Adapt • Depended on wild plants that grew near where they settled • Learned they could plant seeds and grow the food themselves • A SHIFT… • food gathering food producing • Domestication = making plants and animals useful to humans People Adapt • Domestication leads to AGRICULTURE • Farmers raised livestock for milk, meat, and helping on the farm • Since people didn’t have to live to hunt, they could settle in one place. • Stable food allowed for the population to grow. • Not everybody had to farm, so they came up with new jobs and roles. First real signs of Religion • Built large Megaliths- huge stones used as monuments or religious gatherings • Believed that early people believed in gods & goddesses associated with the four elementsair, water, fire, and earth- or with animals. • Some historians believed that prehistoric people prayed to their ancestors.
