Question

Which one of the following phenomena supports Darwin’s concept of natural selection in evolution?

• A. Development of transgenic animals
• B. Production of ‘Dolly’, the sheep by cloning
• C. Prevalence of pesticide-resistant insects
• D. Development of organs from stem cells

Answer 1

The correct option is C

Prevalence of pesticide-resistant insects

One of the features of Darwinism is 'survival of the fittest'. This states that the organisms possessing favourable variations (characteristics) would survive, because they are best adapted (naturally selected) to face their surroundings, while the unfit perish.
Pesticide-resistant insects are naturally selected to survive better than non-resistant insects.
Development of transgenic animals, production of 'Dolly' and the development of organs from stem cells involve human interference or selection by man.
