The duplication of chromosomal DNA molecules takes place during the S phase of interphase.
Evolution is the process by which modern organisms have descended from ancient ancestors.
Evolution is the gradual genetic change of living organisms over time due to ecological pressures they experience. Individuals in an interbreeding population share in a common gene pool. A populationâs gene pool evolves, not an individual, due to changes occurring in such a gene pool. Evolution can occur in several different ways: (1) gene frequencies may be changed by migration, gene flow from another population.
