How is the evolution of a complex organ like the eye correctly explained?
Answer and explanation
Correct answer: Small useful changes accumulated over a long time
Evolution by natural selection does not require a complex organ to appear suddenly in its final form. Heritable variations that provide even small advantages can be preserved because their bearers are more likely to survive and reproduce. Across many generations, successive useful changes may accumulate and produce a complex structure such as an eye. Therefore, option B is correct.
