How did the early man evolve and change into the way we are today?
Human Evolution, the natural development of the species Homo Sapiens, or human
beings. The initial man, called the Hominid was short, not intelligent, and very ape like.
The next man lived in the stone age; his name was Homo Habilis. After Homo Habilis,
Homo Erectus evolved. He was smarter, more efficient, and walked up-right. And he
leaded to us, Homo Sapiens A lot of fossils, bones, and teeth have been found at various
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
shown.
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
environments.
The third major trend in hominid development is the decrease in the size of the face and
