Why is evolution not considered possible without reproduction?
Answer and explanation
Correct answer: Because traits pass from one generation to the next through reproduction
Evolution means heritable changes in populations across successive generations. Reproduction creates new generations and transfers genetic material, including inherited variations, from parents to offspring. Natural selection can act on those heritable differences only when they are passed on. Without reproduction, an individual might change during its lifetime, but that change would not form an evolutionary lineage. Hence A is correct; the other choices are unrelated.
