Question

The principle of natural selection is based on the idea that genetic variations that are adaptive in a particular environment will become more common over time. This is because individuals with these advantageous traits will have a better chance of survival and reproduction, passing on these traits to their offspring. Option A is incorrect because natural selection does not necessarily lead to constant improvement, but rather adaptation to specific environments. Option B is only partially correct, as the environment does play a role in selecting for certain traits, but it is not a conscious process. Option D discusses the idea of traits becoming less adaptive and being replaced by more adaptive ones, but it does not capture the essence of how natural selection works.
