Detailed explanation-1: -Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.

Detailed explanation-2: -Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).

Detailed explanation-3: -The type of selection most likely to increase variation is disruptive (or diversifying) selection, which occurs when two or more pheno-types are fitter than the intermediate phenotypes that lie between them.

Detailed explanation-4: -The population will not only evolve (change in its genetic makeup and inherited traits), but will evolve in such a way that it becomes adapted, or better-suited, to its environment.
