places throughout Africa, Europe, and Asia that proved that early man existed. Tools

made of stone, bone, and wood have also have been discovered and excavated. As a result

of these discoveries, a idea of human evolution during the past 4 to 5 million years has


Most of the ability to make and use tools and other objects comes from the large size

and complexity of the human brain.

through human evolution the size of the brain has

tripled. The increase in brain size may be from changes in hominid behavior. Over time,

stone tools and other artifacts became more complex and the number of them increased.

In addition, the geographic areas occupied by our ancestors expanded during human

evolution. They began to move into the tropical areas of Eurasia sometime after a million

years ago, and into the tropical parts of these continents about 500,000 years ago. Later

hominids were able to cross the water barrier into Australia. It is likely that the increase in

brain size took place to permit our ancestors to be increasingly able to live in a variety of


The third major trend in hominid development is the decrease in the size of the face and
