There are three phases of evolution expressed in the modern theory of evolution. First, genetic variation is produced at three levels. At the level of DNA, [answer1]is a chemical change in the DNA molecule, which gives rise to variation. At the level of the individual organism, [answer2] gives rise to variation during the formation of gamete cells. At the level of the population, migration gives rise to variation. Second, there is a reduction of genetic variation by two processes. One process, [answer3] is the chance (or random) removal of genetic variants due to sampling error from generation to generation. It is especially effective in small populations. The other process,[answer4], eliminates the less fit variants (such as those less successful at avoiding predators or finding food). meiosis reproductive isolation genetic drift natural selection gene mutation
