Darwin's theory, as presented in "The Origin of Species," is mainly concerned with:
Correct answer: A. How new species arise
- A. How new species arise
- B. How adaptations develop over time
- C. The origin of life
- D. The genetics of evolution
Explanation
Darwin's theory, as presented in 'The Origin of Species,' primarily focuses on how new species develop. It outlines the process of natural selection, where organisms that are better adapted to their environment tend to survive and reproduce more successfully. Over many generations, this process can lead to the emergence of new species. While adaptations are important in this process, they serve as a means to achieve speciation rather than being the central focus. Additionally, the origin of life and the genetics of evolution are not covered in Darwin's original work, which lacked the benefit of modern genetic insights.

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.
