Charles Darwin (1809-1882) was a British naturalist renowned for his theory of evolution by natural selection. His seminal work, “On the Origin of Species” (1859), proposed that species evolve over time through the process of natural selection, where advantageous traits are favored for survival and reproduction. Darwin’s theory, developed through extensive research and observations during his voyage on the HMS Beagle, challenged prevailing beliefs about the origin and diversity of life. Despite facing controversy, his ideas reshaped biology and had profound implications across disciplines. Darwin’s legacy as one of the most influential figures in science endures, shaping our understanding of the natural world and sparking ongoing exploration into evolutionary processes.
