Charles Darwin (scientist)

Charles Darwin was an English naturalist and biologist best known for developing the theory of evolution by natural selection. His research demonstrated that species change over generations through a process where individuals with advantageous traits are more likely to survive and reproduce. This natural selection drives the diversity of life on Earth. Darwin's seminal work, *On the Origin of Species* (1859), reshaped our understanding of biology, showing that all living things share common ancestors and evolve through gradual changes over time. His ideas remain foundational to modern biological science.
