Origin of species by Natural Selection included all, EXCEPT:
Correct answer: D. Mutation
- A. Decent with modification
- B. Struggle for existence
- C. Survival of the fittest
- D. Mutation
Explanation
Darwin's theory of natural selection primarily focuses on "Descent with modification," "Survival of the fittest," and the "Struggle for existence," the role of genetic mutations in evolution was not well understood during Darwin's time. It was only later, in the 20th century, that the significance of mutations in the process of evolution was elucidated through the development of modern genetics and the understanding of DNA.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
