Detailed explanation-1: -Sometimes, there can be random fluctuations in the numbers of alleles in a population. These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time.

Detailed explanation-2: -In genetic terms, evolution is the change in the relative frequency of alleles in a population.

Detailed explanation-3: -Define evolution in genetic terms. Evolution can be defined as a change in the relative frequency of alleles in the gene pool of a population.

Detailed explanation-4: -Formally, evolution is a change in allele frequencies in a population over time, so a population in Hardy-Weinberg equilibrium is not evolving.

Detailed explanation-5: -Evolution is change in the genetic composition of populations. In nature, individuals reproduce, die, and move among populations, leading to changes in the population frequency of the alleles they carry.
