Which of the following statements about natural selection is not true?
Correct answer: B. It is selected by a breeder
- A. It affects variations that are heritable
- B. It is selected by a breeder
- C. It can improve the adaptation of species
- D. It is regional in nature
Explanation
When traits are selected by a breeder, this process is known as artificial selection, not natural selection. In artificial selection, breeders choose individuals with specific desirable traits-such as size, color, or temperament-to reproduce, thereby directly influencing which traits are passed on to the next generation. This is different from natural selection, where environmental pressures determine which traits are advantageous, and there is no human intervention. While both processes involve the passing of favorable traits to future generations, artificial selection is driven by human preferences, whereas natural selection is governed by the natural environment

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.
