Ugenics Revisited - Genetic Engineering - Essay Example

Initially Galton presented the eugenics concept but later many of the scientists worked on it just because of its importance. Like many other unique concepts, eugenics also faced criticism for many other expert scientists and public. At the top of the list, the critics claim the concept and practices of eugenics as unethical and immoral practice for the society. According to their opinion, the practices of eugenics are misused and misunderstood by different people. In addition to these opinions, many other expert scientists are of the opinion that the eugenics practices may give rise to many of the genetically diseases.

These diseases are severe and thus cause problems in the entire future generation of the mating people. Due to the increase in the likelihood of these diseases caused by eugenics practices, there is a possibility that the gene variation may get disturbed. The concept of natural selection and genetic engineering is same i.e. the acquiring of the most desired set of traits and characteristics. The only difference is that natural selection is a nature’s ultimate process while the genetic engineering is an optional and artificial process, which anyone can choose on his own opinion (Bradshaw, 2006).

For this reason, it is said that selective breeding is different from the natural breeding, though the basic aim or purpose is same behind both these tools or we can say practices. Genetic engineering is very vast field as it includes many of the gene mutations e.g. a human gene inserted in the goat or sheep, a monkey or frog gene inserted in the shrubs and herbs, a spider gene inserted in the goat and a tree gene inserted in the banana fruit. All of these gene mutations come under the head of genetic engineering, which is different from natural selection in this regard.

In addition to this genetic engineering can benefit many other areas of life e.g. the growth of such crops, which do not need fertilizers and can bear the heat of
