Charles Darwin's 'On the Origin of Species' (1859) proposed natural selection as evolution's driving mechanism, resting on four observations: (1) overproduction — species produce far more offspring than resources can support (e.g. a Salmon's ~28 million eggs per season); (2) struggle for existence — intraspecific, interspecific, and environmental competition for limited resources; (3) universal variation — no two individuals are identical, and useful variations are heritable; (4) survival of the fittest — nature selects the best-adapted individuals to survive and reproduce, gradually adapting populations to their environment. Objections raised against Darwinism include its failure to explain the mechanism generating variation, its focus on the survival rather than arrival …
