Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual’s ability to compete, survive, and reproduce.

What do we come to know from the theory of evolution as proposed by Darwin and Wallace?

Darwin and a scientific contemporary of his, Alfred Russel Wallace, proposed that evolution occurs because of a phenomenon called natural selection. This means that if an environment changes, the traits that enhance survival in that environment will also gradually change, or evolve.

What are the main components of Darwin’s theory of evolution?

Darwin’s process of natural selection has four components.

  • Variation. Organisms (within populations) exhibit individual variation in appearance and behavior.
  • Inheritance. Some traits are consistently passed on from parent to offspring.
  • High rate of population growth.
  • Differential survival and reproduction.
