What is the theory of human evolution?
assistant
The theory of human evolution is the scientific theory that outlines the evolutionary history of the human species from its first emergence to its present form. It proposes that the human species—Homo sapiens—evolved from a transition in the evolution of primates that occurred 5 to 7 million years ago in Africa. This transition is thought to have included the emergence of bipedalism, human brain development and language capability, changes in diet, and the development of a variety of social and cultural behaviours. The theory further proposes that the development of modern humans is due to genetic factors, as well as the environment in which they are found.
