The theory of survival of the fittest was propounded by Charles Darwin. This theory, also known as natural selection, suggests that organisms that are best adapted to their environment are more likely to survive and reproduce than those that are less well adapted. Over time, the traits that contribute to survival and reproduction become more common in the population, leading to evolution. Darwin's theory of evolution through natural selection is one of the most important and influential scientific theories in history.
