<h3>How are gene variants involved in evolution?</h3>

Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes. Genetic variations can arise from genetic variations (also called mutations) or from a normal process in which genetic material is rearranged as the cell is about to divide (known as genetic recombination).

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

Over time, as generations of individuals with the trait continue to reproduce, the favorable trait becomes more and more common in a population, making that population different from the ancestral population. Sometimes the population becomes so distinct that it is considered a new species.
