The Artificial Model Of Natural Selection Essay

Genetic manipulation is a powerful tool that allows humans to selectively modify organisms. It provides the ability for humans to deliberately manipulate an organism 's’ genes in order to produce desirable traits. Genetic manipulation provides the ability for humans to decide which phenotypes to express, and which to eliminate. This typically starts with an individual organism, then goes onto eventually effect and entire species or breed.

We are living is a world where very soon it will be possible for people to create ‘designer babies’ that have all the features they wish for. In the article Building Baby from the Genes Up, Ronald M. Green talks about all the positive impacts that genetic modification of human beings can have on our future generations. Green acknowledges some of the negatives such as parents creating perfect children and being able to give them any trait the parent wants. However in the end he comes to the conclusion that the positive impacts of getting rid of genes that cause obesity, cancer, learning disorders, and many other diseases and disorders, outweighs the negative aspects. Richard Hayes, author of Genetically Modified Humans? No Thanks, takes the stance that we should not be able to change anything about human beings through genetic modification. He believes that once we start modifying a few features, it will slowly turn into every parent altering as many of their babies’ genes that they want. While he does acknowledge the positive impacts of getting rid of negative genes such as Tay-Sachs, he believes that it is not worth the risk of having parents manipulate all their future children’s genes to their liking. Green and Hayes stand on opposite sides of the debate about genetic modification of human beings and this essay will explore the similarities and the differences of their articles.

Throughout our lifetime we are in constant change, many of those changes are ones that you don’t notice. However permanent we set a change to ourselves, one thing we hardly notice change is our DNA. Just growing recently in popularity is genetic engineering , along with its immense potential which can do very much for us, in the future and today. However, with all the potential that genetic engineering carries many people have begun to resent what genetic engineering could become instead of focusing on the great capabilities, and what lies ahead of its bright future. Regardless of what others believe, Genetic engineering will renovate the way we do things today, genetic engineering is a tremendous step to accept, and without a doubt a step

Should human genetic modification be allowed in today’s society? Many experiments with genetic modification on plants and animals involved trial and error. While there was success in the research, there also existed the cost of many errors. Scientists soon want to move onto the next step – genetic modification in humans. The human aesthetic could soon be in the hands of men. Recent advances in technology and research through other life forms have allowed us to consider this vast advancement in genetic modification. In studies of genetic modification, scientists rarely have 100% efficiency. We need to approach the concept of genetic modification in humans with caution. The magnitude of the advancement is immense; therefore, we need to approach this concept at a gradual pace. If we ignore these precautions, we risk human lives and deformities in the name of science. Exploring the possibilities of genetic modification is important to the future of science.

Genetic Modification is often perceived as the answer to humanity’s faults because it will enhance human abilities, prevent the survival of incapacitating disabilities, and guide the innovation of the future. Sounds pretty good, right? That is not the reality. Genetic modification is not the solution to the ubiquitous problems of the human race, but rather infringes on individual rights, decreases diversity, permits too much power to the human race, and contributes to overpopulation.

One of the most famous quotes from the movie “Jurassic Park” states as follows, “Yeah, yeah, but your scientists were so preoccupied with whether or not they could, that they did not stop to think if they should.” This quote by Jeff Goldblum not only interprets his characters wit, but also sparks an interesting debate. “Jurassic Park” brings the idea of genetic modification to people’s attention in an entertaining way. Amazingly, scientists and geneticists are able to alter specific genes, much like in the movie. Many benefits from altering genes exist, but some are viewed as morally unacceptable.

Imagine a world where maladaptive genetic diseases have ceased to exist, parents have the ability to alter and improve their unborn child’s attributes such as height, intelligence, and attractiveness, and each generation becomes healthier, smarter, and stronger. Sounds like an unfeasible utopia, does it not? However, due to scientific advancements in the field of embryonic gene modification, this fantasy may soon become a reality. In a nutshell, embryonic gene modification refers to scientists altering the genome of an embryo in vitro for a multitude of reasons, ranging from eliminating harmful genetic diseases to altering superficial characteristics. Although embryonic gene modification may seem like a dream come true to many, it is not without ethical concerns that require intense debate.

The world we live in is advancing more and more every day. We are beginning to exceed boundaries and reach new limits. Science and Technology has come a long way since Copernicus said that the sun was the center of the universe. Science fiction is slowly coming to life. We are building robots that are extremely similar to humans, modifying genes, and creating clones. Authors wrote about these abstract ideas not too long ago, but at the time they seemed far-fetched. Scientific and technological advancement may be for good or for evil. The good side is the advancements in medicine that could limit the risk of a particular disease or even cure one. The potentially bad side is the steps we may take to get there without knowing the long-term effect. In Michael Bess’s article “Blurring the Boundary Between Person and Product,” he discusses the advancement of genetic

Human progression is a key motive in the field of science and technology. New techniques and designs are made to improve the general welfare and life span of human beings. However, development requires risks and those risks may have deadly effects on future generations. One such debate is over genetic engineering and creating “Designer Babies”. The ability to alter any trait an offspring may possess.

The definition of evolution is that species over time will change. They will start to adapt over time and become a new species. You see this happening throughout the world and over the course of our planets history. In this lab we will be testing different hypothesis and observing them to make conclusions if they can be justified or not. There are three different parts first is the Artificial and Natural selection, the second is the fossil record, third is comparative anatomy, biochemistry, embryology and the last is Biogeography.

It is incredible to see how far genetic engineering has come. Humans, plants, and any living organism can now be manipulated. Scientists have found ways to change humans before they are even born. They can remove, add, or alter genes in the human genome. Making things possible that humans (even thirty years ago) would have never imagined. Richard Hayes claims in SuperSize Your Child? that genetic engineering needs to have limitations. That genetic engineering should be used for medical purposes, but not for “genetic modification that could open the door to high-tech eugenic engineering” (188). There is no doubt that genetic engineering can amount to great things, but without limits it could lead the human race into a future that no one

Stabilizing selection favors intermediate phenotypes within a range. The extremes of the variations are selected against. Children weighing significantly less than or equal to 3.4 kg have higher rates of infant mortality. The selection works against both extremes. In this type of selection, the intermediate phenotypes are favored and radical phenotypes are eliminated at both ends of a continuum of variation.

Genetics is a world of unknown limitations. From the small fraction of application seen being explored today, they have yet to even begin exploring its true wonders and comprehend its beauty as an entirety. As of today, animals and plants have been the only beneficiaries of genetic research and experimentation (National Human Genome Research Institute). Such experiments have led to the development of better chances of survival of modified organisms against harsh environments. Pigs and cows are an example of how organisms can be modified to better effect the environment (Moss). Corn is an example of how crops can be adapted for other, previously unsuitable areas such as Africa (Glenn). Animals and plants have greatly benefited from genetic modification and research, but why should they be the only ones to get such great results. Humans should be granted the right to

Within the last 100 years or so scientists have many valuable discoveries that have benefited mankind. These discoveries include the discovery of genes. Scientists have discovered what makes humans so unique from one another. However, with this newly gained knowledge of the function of genes comes the ability to alter or change them. Just imagine in the not so near future, you and your partner want to start a family together. You travel to your local gene councillor to pick the physical and characteristic traits of your child. That’s right. With the knowledge that has been gained about genes, scientists can “create” the perfect child genetically. The thought is scary. Nature has always taken us down the right path but are we really ready
