Human Selection Vs Natural Selection

Improved Essays
Natural evolution has altered many organisms over time, including humans, (Homo sapiens) in the past. However, for the present and the future of humanity, I believe that natural human evolution will not continue, as humans have taken control of their evolution. First, humans are able to artificially alter their physical appearance to be more attractive, causing sexual selection to alter the gene pool less and less. In addition, people are able to remove the pressures which question the fitness of individuals using medical technology. Finally, as genetic research continues to advance, humans can alter their genes and the genes of their children to bypass natural selection in the process of improving the species.
The first factor which allows

Currently, gene therapy, which can alter genes in one organ at a time, is being developed to cure diseases (Ward, 2009). With this technique, humans have the ability to remove the genes which cause disorders and diseases without killing the individuals who carry these genes. This method of gene selection is faster than natural evolution because it allows immediate removal of unfavourable genes, while natural selection occurs over many generations. Therefore, gene therapy can quickly outpace natural selection, giving humans complete control of their evolution. Additionally, advances in genetic modification through germ-line therapy could allow parents to genetically engineer their children, making them more intelligent, attractive and removing predispositions for disease (Ward, 2009). This type of genetic modification allows the production of an offspring which is more fit to survive without relying on chance to produce the perfect combination of parent genes. If foreign genes which do not belong to either parent are used to improve the offspring, the concept of inherited traits is also rendered obsolete. People can take control of their evolution by choosing their genes and the genes of their children, something which no other organism has the ability to do. Due to the fact that …show more content…
By manipulating sexual selection, eliminating natural selection and outpacing natural evolutionary processes, humans are able to evolve unlike any other organism: through artificial means. Most organisms cannot learn to adapt; they either have adaptations which allow them to survive or they do not. The image of a beaver learning to use a chainsaw comes to mind, a caricature which demonstrates the impossibility of adaptation through learning. When one observes Homo sapiens, however, it is evident that this species depends on its unique ability to learn in order to survive. Humans are the only organisms to which Lamarck’s theory applies; they learn to develop new technologies throughout their lifetimes and pass them on to future generations, which improve upon their ancestors’ designs and discoveries. Humans strive for perfection, as seen with advances in cosmetics, medical technology and genetic modification, and this ability to consciously seek out ways to improve themselves allows the human race to completely control its

    Walters and Palmer believe that genetic treatment may be the only way to avoid many genetic disorders for some people. When an embryo undergoes germ-line therapy early enough, the embryo has a great potential to prevent irreparable damage to the developing embryo and thus be disease free. However, it then causes all cells of the embryo to be genetically modified. Germ-line therapy, as previously stated, prevents the transmission of genetic diseases through the generations, unlike somatic cell therapy. It is then more efficient to undergo germ-line therapy than somatic cell therapy.…

    They are either caused by mutation(s), or are inherited from biological parents (“National Human Genome”). Effects of genetic disorder vary depending on severity of the mutation. Many available options are aimed at reducing the symptoms, not at diminishing the cause. However, with CRISPR, it is now possible to fight genetic disorder before it even develops. In an experiment done by Wu et al, researchers in Shanghai Institutes for Biological Sciences, the spermatogonial stem cells (precursor to normal body cells) with a genetic mutation underwent gene therapy.…

    As the scientists conducting this experiment want to find an easier/more accessible treatment for infections which overpower the immune system. The use of gene regulation helps allow DNA replication through mRNA. There can be some complications with gene regulation. As a gene needs to be turned ‘on’ in the right place, at the right time, and to the right level that is needed in order to function well. To address this situation, there is a prevention for the cell to stop making the protein that the gene encodes, to repair the gene, or find a way that is aimed at blocking or eliminating the protein.…

In “Gene Editing Hope For New Cures Or Scary Science “genetic editing with a new system allows for the rapid modification of the DNA of almost any organism, It’s quick, and that can allow for mistakes to happen safety wise, because every gene editing case is different and with the fast construction there is a possibility of accidentally cutting out the wrong…

    Passing on altered genes that can ultimately eliminate diseases such as cancer, cystic fibrosis, and even Alzheimer’s disease can improve the quality of human life exponentially. These newly acquired genes can be modified back to their original configuration or engineered ever further to achieve the desired result many generations later. Germline manipulation has sparked an enormous amount of controversy and scientists and people everywhere have great arguments for and against germline manipulation. Pros One of the biggest reasons why scientists are pushing for the advancement of germline manipulation is to end diseases. Human genetic engineering was devoted to helping end the spread of diseases, as well as genetic defects and…

    Lewis’s article is important because it illustrates the effects of genetic modification on the embryo’s health. Genetic engineering can cause deletions and alterations to the DNA, affecting negatively it’s natural functioning and what is produced. Also, genetic modification consists of removing undesired genes from the embryo. It is a one-way change. The changes made to the genes cannot be unchanged, and thus these changes will be inherited by the future generations.…

    (ABPI) This process makes the insulin much safer and gets rid of the possibility of being contaminated from the sample it was harvested from (ABPI). From the production of insulin to the elimination of disease, genetic modification offers many benefits to humans. Genetic engineering could be used to modify unborn children to rid them of illnesses or diseases that they would have to live with for the rest of their life or could possibly kill them (Rinkesh). Stephen Hawking once spoke about how genetic engineering could be used to better the human race: "With genetic engineering, we will be able to increase the complexity of our DNA, and improve the human race. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code."…

    He states that the four main concerns about gene manipulation are the effect of gene modification on the parents, our freedom, our social divisions, and people’s religions. The first concern is if parents will replace the love for their child “with a consumerist mentality that seeks perfection” (Green 2). Parents who wish for healthy children and have one born with disabilities love their child unconditionally regardless of having perfect genes. Gene modification would not change this fact because “that child is already remarkably influenced by the genes they inherit” (Green 3). The second concern is if our freedom will be diminished “by making us creatures of our genes or of our parents’ whims” (Green 2).…
