Natural selection will only cause evolution if there is enough genetic variation in a population. Before the discovery of Mendelian genetics, one common hypothesis was blending inheritance. But with blending inheritance, genetic variance would be rapidly lost, making evolution by natural selection implausible.
âA mutation doesnât produce major new raw material. You donât make a new species by mutating the species. . . Thatâs a common idea people have; that evolution is due to random mutations. A mutation is not the cause of evolutionary changeâ (as quoted in Sunderland, 106). The second mechanism for alleged evolutionary change is the process of natural selection. This idea was the major thrust of Darwinâs 1859 book, The Origin of Species. Evolutionists argue that: 1  organisms within each species vary; 2  these variations may be inherited;
