Detailed explanation-1: -Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

Detailed explanation-2: -In population genetics, the term evolution is defined as a change in the frequency of an allele in a population. Frequencies range from 0, present in no individuals, to 1, present in all individuals.

Detailed explanation-3: -By devising models of gene frequency change, population geneticists are thus able to shed light on the genetic basis of evolutionary change, and to permit the consequences of different evolutionary hypotheses to be explored in a quantitatively precise way.

Detailed explanation-4: -Evolution is possible when there is variation in the genetic makeup among organisms that affects their traits. Then, if certain individuals in a population reproduce more successfully than others so that their traits become more common within the population, the result is evolutionary change.
