Charles Darwin's original concept refers to the theory of evolution by natural selection, which proposes that species evolve over time through the process of variation and survival of the fittest. This idea emphasizes that individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to future generations. Darwin's work challenged existing beliefs about creation and laid the groundwork for modern biological sciences, influencing not just science but also social theories in the years that followed.
