Detailed explanation-1: -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-2: -There are five key mechanisms that cause a population, a group of interacting organisms of a single species, to exhibit a change in allele frequency from one generation to the next. These are evolution by: mutation, genetic drift, gene flow, non-random mating, and natural selection.

Detailed explanation-3: -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.

Detailed explanation-4: -Evolution Is Change in the Inherited Traits of a Population through Successive Generations. Evolution describes changes in inherited traits of populations through successive generations. To fully understand the science of ecology, one must first be able to grasp evolutionary concepts.
