In the 19th century, biologists, especially Charles Robert Darwin (born 12 February 1809), announced his theory about the process of human biological evolution. According to his theory, the oldest forms of human life on the face of the earth consisted of very simple one-cell creatures such as protozoa/a kind of tadpole (child of a frog), over time over millions, billions and years, they emerged and developed. "living forms in the form of creatures with self-organization (forming groups) that are increasingly complex over time, and in recent times have developed or evolved, finally becoming apes and humans."
