If an organism looks simple today, is it correct to call it backward in evolution?

Answer and explanation

Correct answer: No; it may be well adapted to its environment

Evolution does not follow a universal rule that organisms must become increasingly complex. Natural selection favours traits that improve survival and reproduction in a particular environment, and a relatively simple body plan can remain highly successful for a long time. Consequently, present simplicity does not mean evolutionary failure or inferiority. Option A is correct. B and C promote the ladder misconception, while D is false because simple organisms also possess genetic material.
