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: -Evolution is the change in characteristics of populations of organisms over time. Changes can be small, for example, a small change in body size or a change in the color of a species’ fur.

Detailed explanation-3: -Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes.

Detailed explanation-4: -Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.

Detailed explanation-5: -Formally, evolution is a change in allele frequencies in a population over time, so a population in Hardy-Weinberg equilibrium is not evolving.
