उत्तर
Both A and R are True.
Explanation:
Charles Darwin’s theory of natural selection is an important mechanism of evolution, including human evolution. Therefore, the Assertion (A) is true.
Natural selection favours heritable variations that improve an organism’s chances of survival and reproduction. Over generations, such favourable variations become more common, leading to adaptation and evolutionary change. Therefore, the Reason (R) is true.
Hence, both A and R are true.
