Explain the concept of natural selection in evolution.
Natural selection is the mechanism by which individuals with advantageous traits are more likely to survive and reproduce, leading to the evolution of species over time.
Natural selection occurs when species randomly change without environmental influence.
Natural selection is the process where all traits are equally favored in survival.
Natural selection is the idea that evolution happens only through genetic mutations.
