Early Human Migration
Tools and Technologies
-
New tools defined the Mesolithic Era, or Middle Stone Age that began more than 10,000 years ago and lasted until about 5000 years ago.
During this time, people found new uses for bone and stone tools.
-
-
In addition to tools, people developed new technologies to improve their lives, such as canoes made from hollowing out logs and pottery.
-
Early people adapted to their new environments with new kinds of clothing, shelter, tools, and other inventions.
Ice Ages
-
Ice Covered most of the land: 
-
Ice sheets were formed from ocean water - ocean levels were lower than they are now (areas under water today were dry then).
Some scientists believe that the ocean level dropped and exposed a land bridge that connected Asia and North America, that allowed Stone Age people to migrate around the world.
Settling New Lands
-
-
-
As humans began to migrate around the world, earlier hominids died out.
-
They also learned to build homes above ground. Some lived in tents made of animal skins. Others lived in more permanent homes made of wood, stone, clay, and even large mammoth bones.
-
As people moved to new lands, they found they had to adapt to new and different environments.
Fire helped to keep people warm, but they needed more protection so they learned to sew animal skins together to make clothing.
People also needed protection from the environment so they built shelters when caves weren't available.

NORTH INTO THE AMERICAS
From northern Asia, people moved into North America.
-
-
Once in North America, people moved south, following herds of animals and settling South America.
ASIA
Humans began to migrate from E. Africa to Southern Africa and southwestern Asia around 100,000 years ago.

NORTH INTO EUROPE
From southwestern Asia, humans migrated north into Europe.
Geographic features (high mountains and cold temperatures) delayed migration northward into northern Asia, but people eventually migrated into that region.

By 9000 BC, humans lived on all continents of the world except Antarctica.
