Question

The adaptation shown by the bacterium Pseudomonas for metabolization of nylon is an example of

• A. Genetic variation
• B. Natural selection
• C. Neo-Lamarckism
• D. None of the above

Answer 1

The correct option is B Natural selection

Pseudomonas is the genus of a bacterium. This bacterium was placed in the medium where only nylon was present. This resulted in the development of the bacterial species which was able to metabolize the nylon. The nylon was the only source of food available so, the organism adapted itself to feed on the nylon. This is an example of natural selection.

Thus, the correct answer is option B.
