Summarize natural selection using the words population, individual, gene, mutation, evolve, survive and reproduce

Answer 1

A mutation in an individual's gene allows the individual to better survive in its environment than other members of the population, making it more likely to reach reproductive age and produce offspring with the trait. The members of the population with the trait will then be more likely to reproduce, causing the population as a whole to evolve and select for this trait over many generations.
