Charles Darwin was an English naturalist whose theory of evolution by natural selection, set out in On the Origin of Species, transformed biology and our understanding of life itself.
Charles Darwin developed his revolutionary ideas over decades, drawing on observations made during his voyage aboard HMS Beagle, including his famous studies in the Galápagos Islands.
His masterwork, On the Origin of Species (1859), proposed that species evolve over generations through the process of natural selection, providing a unifying explanation for the diversity of life and overturning prevailing views of creation. His later works, including The Descent of Man, extended the theory to human origins.
One of the most influential scientists in history, Darwin reshaped biology and the modern understanding of nature, and his ideas remain foundational across the life sciences.
