If a trait helps an organism survive but does not pass to offspring why will its effect on evolution be limited?
Answer and explanation
Correct answer: Because evolution needs the trait to pass through generations
Natural selection can influence evolution only when a beneficial difference is heritable. A trait may help one individual survive, but if it is not transmitted to offspring, it will not become more common through reproduction. Evolutionary change requires inherited variation to persist and alter the composition of a population over generations. Option A is correct. Survival is relevant, but without inheritance its advantage generally ends with that individual rather than spreading through the lineage.
