1. Early Human Migration- Classzone.com Animation Early Human Migration It is thought that the first hominids appeared in East (1) Africa about 4 million years ago. They were (2) hunter-gatherers and moved from place to place in search of (3) food to support their growing numbers.

2. Most scientists think that Homo erectus was the (4)1 st hominid to migrate out of Africa. Starting about one and a half million years ago, some Homo erectus moved north into (5)Asia and Europe. Homo sapiens replaced Homo erectus about 100,000 to 250,000 years ago. They too moved out of Africa, but they used their skills and (6)tools to build rafts to travel to Indonesia and eventually (7)Australia. Between 20,000 and 35,000 years ago, an Ice Age froze huge amounts of the (8)oceans’ water. This caused sea levels to drop and exposed the Bering (9)land bridge between Asia and North America.

3. Homo sapiens crossed the Bering land bridge and spread out into (10)North America. Imagine being able to walk from Siberia to Alaska! The movement of (11)glaciers pushed humans further south. Their (12)migration took them all the way down to the tip of South America. The Ice Age ended about 10,000 years ago. (13)Melting ice raised sea levels, and the Bering land bridge was once again swallowed by the sea. Humans were now living on every continent except (14)Antarctica.

4. KEY UNDERSTANDINGS: WHAT DOES MIGRATION MEAN? MIGRATION IS MOVING FROM ONE PLACE TO ANOTHER NAME TWO REASONS WHY EARLY HOMINIDS MIGRATED FROM AFRICA. 1) Food 2) Climate HOW DID EARLY HOMINIDS MOVE FROM CONTINENT TO CONTINENT? They built rafts or walked over glaciered land bridges between the continents before the end of the Ice Age.

5. The First Humans Hominids are the family of mankind and his or her relatives.

6. 65 Million Years Ago DinosaursDinosaurs died out about 65 million years ago. The first human like hominids did not appear until around 3 million years ago. No matter what you may have seen in the movies, early man did not live during the same period in history as dinosaurs! Not that early man had it easy, but he did not have to fight dinosaurs!

7. 3 Million Years Ago 3 million years ago, our planet was teeming with life! There were deer, giraffes, hyenas, sheep, goats, horses, elephants, camels, beavers, cave lions, ants, termites, woolly mammoths, saber-toothed tigers, giant sharks, dogs with huge teeth, and all kinds of birds and plants and fish.

8. Very Early Humans It was during this time that the higher primates, including apes and early man, first appeared. Their hands were different, too. Ape hands were made for climbing and clinging. Man’s hands were jointed differently, which allowed them to make and use tools. There was a difference between apes and man. Early human-like hominids could stand upright. Apes could not.

9. Very Early Humans How do scientists know about an early man who lived 3 million years ago? Lucy told them!

10. Lucy In 1974, a skeleton was found in Africa. The bones were those of a female, about 20 years old or so when she died. Scientists named her Lucy. About 3 million years ago, when Lucy was alive, she was about 4 feet tall and weighed about 50 pounds. Scientists suspect that she fell into a lake or river and drowned. Scientists are like detectives. They can tell a great deal from a skeleton, whether it's one year old or 3 million years old!

15. Fossils & Artifacts Scientists use many clues to help them put pieces of the past together. One thing they must know is the difference between a fossil and an artifact. Artifacts are remains of things that were made, not remains of living things. Fossils are remains of living things (plants, animals, people), not things that were made.

16. Stage 1-Homo Habilis- “Handy Man” First to make stone tools 2.5 million years Ago

17. Handy Man These early human-like hominids were taller and smarter than Lucy’s people, but they did not know how to make fire. When they broke camp, they probably tried to bring fire with them by carrying lit branches to use to start a new campfire. If their branches went out, they did without fire until they found something burning.

19. Upright Man Many years passed. Another group of man was born. Scientists nicknamed this group “Upright Man”. Upright Man did know how to make fire. That changed everything! People began to cook their food, which helped to reduce disease. People collected around the fire each night, to share stories of the day's hunt and activities, which helped to develop a spirit of community.

20. Upright Man These Stone Age people were about the same size as modern humans. Their tool-making skills were considerably improved. Their weapons included stone axes and knives. Because Upright Man could make fire, he was free to move about in search of food. He did not have to worry about freezing. He made warm clothes from animal skins. At night, he built a campfire to cook his food and to stay warm.

21. Man Leaves Home About one million years ago, Upright Man began to slowly leave Africa. These early people began to populate the world. Scientists have found artifacts of their tools and weapons, which help us to understand how they lived, where they went, and how they got there. They did not need a boat. The Ice Age was here! They traveled across giant walkways of frozen ice, over what later would become vast rivers and seas.

24. Neanderthals *Neanderthals were different from other species of early humans. *They were tall and smart * lived in caves *They were great hunters. Considering how smart they were, and how advanced for their time, scientists are puzzled that the Neanderthals were one of the early species of man to die out. Many species of man died out in these early days. But why the Neanderthals? It is a history mystery.

26. Cro-Magnon Man Another group of early men stood out during this period. Scientists nicknamed this group “Cro-Magnon man”. Cro-Magnon man lived in Europe. This group did not live a life of constant struggle for survival because they worked together to provide food for their tribe.

27. Cro-Magnon Man These Stone Age people learned to cure and store food for the long winter. They used traps, which allowed them to catch food while they were busy doing something else. Fisherman used nets woven from vines and fishhooks. Some groups built rafts and canoes to catch bigger fish in deeper waters. They made clothing and jewelry. They invented the bow and arrow.

28. Cro-Magnons About 10,000 years before Neanderthals vanished, the Cro-Magnons appeared. About 10,000 years before Neanderthals vanished, the Cro-Magnons appeared. Their bodies were just like those of modern people.Their bodies were just like those of modern people.

They may have also had more skill at speaking than Neanderthals.They may have also had more skill at speaking than Neanderthals. Because they had these skills, the Cro-Magnons were better at finding food. That may explain why Cro- Magnons survived and Neanderthals did not. Because they had these skills, the Cro-Magnons were better at finding food. That may explain why Cro- Magnons survived and Neanderthals did not.

29. During this time people found shelter in caves and left behind very interesting artifacts

30. Cave Paintings Cro-Magnon man did something rather unusual. For some reason, he drew paintings deep inside dark caves, on cave walls.he drew paintings His paintings were added to the paintings already on the cave walls, left by other Cro-Magnon men. Over time, a cave might accumulate hundreds of paintings. Colors used most often were brown, yellow/tan, dark red, and coal black.

31. Clovis First Americans Hunted large mammals such as the woolly mammoth Crossed land bridge from Siberia to Alaska About 12,000 years ago

32. Recap We know about early Stone Age people because scientists have found fossils and artifacts that reveal traces of their life. Man went through many stages to evolve into the humans of today! Since this evolution covers roughly 3 million years, you might say it took man a long time to grow up!evolution
