Charles Darwin (naturalist)

Charles Darwin was a 19th-century naturalist who developed the theory of evolution by natural selection. He observed that species gradually change over generations as individuals with advantageous traits are more likely to survive and reproduce. His famous work, "On the Origin of Species," explained how diverse life forms share common ancestors and adapt to their environments over time. Darwin’s ideas revolutionized biology by providing a scientific explanation for the development of life on Earth, emphasizing the importance of natural processes in shaping the diversity of living organisms.
