Why is evolution difficult to observe directly with our eyes?
Answer and explanation
Correct answer: Because it occurs over a very long time
Evolution is a population-level change in inherited characteristics across successive generations. It usually results from many small variations, selection, and reproductive differences accumulating over long periods, often far beyond a human lifetime. Consequently, a person generally cannot watch a complete evolutionary change directly, although fossils, comparative anatomy, embryology, and genetic evidence reveal it. Option A is correct; B, C, and D are scientifically irrelevant or contradictory.
