How Humans Evolved From Early Ancestors
Scientists believe that humans evolved from ape-like ancestors over a very long time. This process of change, called human evolution, started about six million years ago.
One of the first important human traits was walking on two legs, which developed more than four million years ago. Later, humans developed larger brains, learned to make tools, and gained the ability to use language. Most of these changes happened in Africa, where the earliest human fossils have been found.
Today, scientists study fossils and ancient tools to understand how early humans lived and changed. This knowledge helps us understand the origins of our species and the defining traits of modern humans.
