What Did Charles Darwin Discover?

Updated: June 09, 2023
Charles Darwin discovered that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection.
Detailed answer:

Charles Darwin was an English naturalist and geologist. He is best known for his theory of evolution. This theory suggests that all species of life have descended from a common ancestor. The mechanism by which evolution occurs is natural selection.

Darwin’s theory of evolution is supported by a large body of evidence, including fossils, biogeography, and comparative anatomy. Evolution has been observed in the lab and in the wild; it has been observed in nature as well as in the lab; it has been observed on multiple continents at different times during Earth’s history; it has been observed on every continent except Antarctica (and even there, penguins are evolving). Evolution is a fact.

Natural selection is not just a process that allows populations to adapt to their environments over time—it’s also a primary mechanism of evolution because it contributes directly to genetic variation within a population. Sexual selection can also drive evolutionary change when there are differences between males and females in their reproductive success due to different mating preferences or behaviors.
