Selection is:
Correct answer: C. Both
- A. None of these
- B. Natural
- C. Both
- D. Artificial
Explanation
There are two types of selection: natural and artificial. According to Charles Darwin, evolution happens by natural selection. Individuals in a species show variation in physical characteristics, as a consequence of which, only the most suited to the environment survive and, given enough time, the species gradually evolve. On the other hand, the artificial selection also known as selective breeding occurs when humans choose organisms with desirable traits and inter-breed them in order to get offsprings that are better and stronger than both the parents.

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.
