What evolved human beings?

According to the current theory of human evolution, human beings evolved from apes.

Modern scientific research shows that apes are the early ancestors of human beings, and human beings developed from an ape. Modern genetic research also shows that there is a close relationship between humans and modern apes, and their * * * distant ancestors are protozoans and Egyptian apes who lived in Fayoum depression in Egypt 3-35 million years ago.

Especially around the 2th century, in recent decades, Lamarcinopithecus, Australopithecus forest and Australopithecus found in many areas of Asia, Africa and Europe are considered as the * * * same ancestors of human beings and modern apes. The discovery of a new species of people in South Africa 2 million years ago provides the latest evidence.

according to the theoretical basis in the theory of evolution, a long time ago, our ancestors could not walk upright or use tools, and their brains were similar to ordinary apes before they evolved. But after a certain time, our ancestors, that is, apes. I learned to walk upright, and began to slowly stop crawling, and my spine slowly developed until I walked upright. It is because of walking upright that our brains developed rapidly and our ancestors learned to use tools. This is a crucial matter, because the fundamental difference between humans and animals is whether they can make and use tools.
