The future of the human maturation - Essay casefulIn his book, Darwin of the eighties, sought to explain the evolution of man as a process of natural selection. Darwin proposes iv elements of natural selection. First, he argues that characters within a population exhibit variations in appearance and conduct. This may be in terms of height, skin color or even body size. Darwin also talks about(predicate) heritcapable traits, which be passed on from parents to offspring as opposed to traits powered by environmental conditions. His trinity component concerns population growth, which at times leads to mortality in cases where the resources cannot support the high population. The fourth component is derived from the third, in which Darwin argues that individuals with desirable traits pass on always survive in such an environment and give mug up the next gen sequencetion. This is known as natural selection, in which individuals struggle to survive and nature favors the strong. Bas ed on this theory, human beings then have a high chance of evolving, powered by the advancement in technological innovations, which will enable them survive. Variations among individuals within a population are occasioned by genetic differences. Genes are the materials through which traits are inherited from parents to offspring. ... Not all mutations are detrimental a mutation in the brain of the Australopithecus enabled him to develop a larger brain and evolve into a hominid. Technological knowhow, however, has been seen to deputise with natural selection. Today, medics have come up with medicine to prolong the lives of mutants, thus encouraging the survival of weaklings which in the long run affects future generations. This means that individuals with desirable traits might mate with mutants and bring forth changes in the human race. This will lead to evolution, which will be occasioned by mutation. Consequently, future generations of human beings might not be able to survive. This not withstanding, not all mutations are negative. Some mutations may be advantageous to the human race. This sensing has led to medical practitioners trying to come up with genetically modified human beings known as clones. These clones are designed to have all the positive attributes of their original humans and thus be more than suitably adapted to live on earth. Human migration might also affect future evolution in terms of gene flow, which is a process of interbreeding between different populations of a effrontery species (Mayr pp.55). When a person migrates from his original place of birth to go to another country, he is bound to egress a family with the local people. This leads to the emergence of a new breed of people carrying the genes of both parents. An example of this is the era of the trans-Atlantic trade in which, many able bodied African men were shipped off to the United States to prepare as slaves. They later married the local women and gave rise to the Afr ican Americans. The latter were seen to have inherited closely of
