Which theory tells about adaptation?
Correct answer: A. Darwin's theory of natural selection.
- A. Darwin's theory of natural selection.
- B. Lamarck's theory of inheritance of acquired characteristics.
- C. Hardy-Weinberg principle
- D. None of these options are correct
Explanation
Darwin's theory of natural selection is the correct answer because it describes how species adapt to their environments over time through the process of natural selection. This involves the differential survival and reproduction of individuals based on their traits, leading to populations that are better suited to their environments.Lamarck's theory, in contrast, focuses on the inheritance of acquired traits, which is not supported by modern genetics. The Hardy-Weinberg principle addresses genetic stability rather than adaptation. Therefore, the correct choice is Darwin's theory of natural selection.

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.
