Evolution: Mutation, Natural Selection, Genetic Drift and Gene Flow Es

What is exploitation and how does it work? Evolution is the theory of how one work out of life tacks into another form. Evolution in any case is the change of a existences inherited traits from generation to generation. Evolution helps to explain why an animal, human, and coiffe looks the way it does and acts the way it does it gives an explanation of the history of life. Genes come in legion(predicate) varieties and the evolution helps to make it happen. Mutation, natural selection, inherited bluster, and gene flow the quaternary forces that make the evolution work. Mutation happens when the DNA gene gets changed, moves, or is damaged. When this happens it causes the transmittable message to be carried by that gene to be different. This process toilet occur in somatic cells. The somatic cells ar all the cells that are a living organism except the reproductive cells, meaning the body. For example, the trim cells on your legs are and leave alon e not be passed on to ones offsprings. In addition those leg cells will not effect the evolution. Another event is called gametic diversitys, which is in a womans eggs and or in a mans sperm. These are cells that are and can be passed on to ones offsprings, and they are the essentials for the evolution. There are three effects mutation causes to a species. Species can only takes on one of the three. The three effects are bad, neutral, and good. Having a bad mutation can cause one to have a harder time being able to survive. Having a neutral mutation will not change or help one to survive. Having a good mutation will help one to survive and have a better candidate of survival. However, mutation is random in the evolution, and provides raw material for natural selection, catching drift, and gene flow... ...he genetic differences making more of a variation simply it does this process slowly. Evolution is a on going process and the evolution is made up of many different processes. It allows species to become what they are, how they act, and what they will become. It also allows species to be able to survive. It produces impertinently and different species through ancestral populations of organisms and moves them to new population. Both natural selection and genetic drift decrease genetic variation. If they were the only mechanisms of evolution, populations would eventually become homogeneous and further evolution would be impossible. There are, however, mechanisms that replace variation depleted by selection and drift (Colby). Work CitedColby, Chris.
