Origin of Species by Natural Selection included all except
Correct answer: D. Mutation
- A. Descent with modification
- B. Struggle for existence
- C. Survival of the fittest
- D. Mutation
Explanation
Darwin's theory of natural selection, as presented in 'On the Origin of Species,' focuses on concepts such as 'Descent with modification,' 'Struggle for existence,' and 'Survival of the fittest.' These ideas highlight the processes of adaptation and selection in the evolution of species. However, the concept of 'Mutation' was not part of Darwin's original framework. The understanding of mutations as a source of genetic variation was developed later, with advances in genetics providing insight into the role of DNA and genetic changes in evolution.

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.
