Human Genetic Engineering: Unnatural Selection

Introduction As technology is a rapidly growing field, it has an important global impact. Modern biotechnology is at the forefront of this influence. From the discovery of DNA to the cloning of various animals, genetic engineering research has changed the view of society's lives. But whether genetic engineering has the ability to influence the best ability of the world. Genetic engineering products can have serious adverse effects on our society.

As long as humans cultivate crops and livestock, they already do genetic manipulation. By selectively cultivating animals and plants with the most advantageous features, early farmers were able to develop genetically engineered species according to their needs. Genetic engineering imitates the process of natural selection, but selective breeding speeds up the process and chooses the most beneficial function for human beings. The concept of modern genetic engineering - manipulating genetic sequences in the laboratory to create a white coating of modern Franconian organisms - began in the second half of the 20th century. After James Watson and Francis Crick found DNA double helix in 1953, scientists soon made rapid progress in operational genetics.

Humans have changed species genomes for thousands of years by selective breeding or artificial choice: 1: 1 was recently induced by mutagenesis compared to natural selection. Since humans manipulate DNA directly outside reproductive and mutant genetic engineering has existed since the 1970's. The term "genetic engineering" was originally built in Jack Williamson's science fiction "Dragon Island" published in 1951 - a year ago, the role of DNA in genetics was obtained by Alfred Heh It was. Ershi and Martha Chase confirmed that James Watson and Francis Crick demonstrated that the DNA molecule has a double helical structure two years ago - the general concept of direct gene manipulation was Stanley G. Weinbaum's 1936 SF The story in is explored in the main form of Proteus Island.

Many genetic engineering critics consider genetic repair "unnatural". Frank criticism against genetically modified organisms (GMOs) has been on this technology and agricultural products for many years, because safety concerns and concerns about modifying the DNA of organisms lower food safety and growth safety. I have protested. However, we are entering an era when humans are genetically modified organisms, and the health and happiness of many people depend on the ability of genetically modified cells. It seems to be meaningless to maintain a means of "natural" death at first glance. We will influence and design most of our world to satisfy our needs. We use things we do not need to survive, such as hearing aids and prosthetic appliances, but these things make our lives better, not to mention the folds of the abdomen and breast implants. For centuries, we have done unnatural things for our bodies.
