Which of the following processes resulted in the production of different breeds of domestic dogs and pigeons?
Correct answer: C. Artificial selection
- A. Natural selection
- B. Cross breeding
- C. Artificial selection
- D. Self breeding
Explanation
Artificial selection is the correct answer because it is a process where humans actively choose which traits should be passed on to the next generation, leading to the creation of different breeds of domestic animals such as dogs and pigeons. Natural selection is driven by environmental factors without human influence. Cross-breeding mixes traits from different breeds but it isn't controlled with the precision of artificial selection. Self-breeding does not involve selective pressure imposed by humans.

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.
