Artificial Selection

Darwin was always aware of the importance of artificial selection, but it was not until after Darwin began reading Malthus that he applied sexual selection to evolution During the year he formed this theory, Darwin read literature on animal breeders. From these animal breeders, Darwin developed some worthy concepts like the importance of diversity among organisms in a herd. Darwin added a key component to his theory on natural selection by studying the practice of artificial selection. This was important in advancing Darwin’s theory because it supplied him of part of the experimental proof that he needed to prove his theory of evolution by natural

Both genetic engineering and artificial selection allow humans to change a species so that its members are better suited for human needs. However, the mechanism for change is different. Artificial selection selects for traits already present in a species, whereas genetic engineering creates new traits. In artificial selection, scientists breed only individuals that have desirable traits. For example, scientists may breed (cross pollinate, in this case) only the highest yielding crops with one another for many generations. The result is a population of plants that all produce a higher yield (e.g., abundant fruit production) than other members of the species. Through selective breeding, scientists are able to change the traits in the population.

Everything in life has a system. A system of equations, a subway system, and even your organ system, all able to operate at close to near perfection as the known. However, if one of these system are manipulated into the unknown the results might be disastrously: a crash or organ failure. With human genetic engineering, the societal results are entirely unknown. Human genetic engineering is a cause that will expand the belief in what is justifiable in the areas of philosophical, moral, and ethical backgrounds. Despite the benefits human genetic engineering, it can also lead to negative social and psychological consequences such as a creation of an underclass (Napolitano, Oladele), and a loss of individuality. Human genetic engineering will cause more social consequences that will evidently outweigh its benefits.

Then there is no watermelon for this poor person who simply wanted a slice. There are a few cons when it comes to genetically modifying the genes of any organism. Genetically modifying organisms can contaminate food crops, and it is potentially dangerous to the animals, plus the pharmaceuticals can harm human health.

One of the benefits of GMOs in agriculture is the viability of sustainable food production. A potential problem with GMOs is the possibility of cancer from high nitrogen and other chemical pollutant levels. These are caused by synthetic pesticides, potential waste problems, and genetically modified foods. I find the argument for non GMOs to be more persuasive because it avoids the potential of cancer, allergies, antibiotic resistance, pesticide exposure, and environment

Genetically modified foods could produce new toxic substances, and/or allergens. A gene was inserted into the DNA of a soybean plant to increase the nutritional value of the soybean. However, this particular gene in the genetically modified soybean also produced an allergen. Fortunately, the plant was not put into production. Another example is of a genetically modified tomato called flavor saver. The tomato is larger, tastier, and stays fresher longer than commercial tomatoes on the market. Combining conventional tomato genes with the genes of an arctic trout produces the flavor savor. Nevertheless, questions such as “Will people with seafood allergies be able to consume the tomato?” and “Will the trout genes in the tomato enable new bacteria growth, and thereby make the tomato hazardous to eat?” have still not been answered. This causes the flavor to be a potential hazard

For years, the health and safety of genetically modified foods have been debated and researched by scientists, but the question still stands: should genetically modified foods be allowed for consumption? The process of genetic modification involves inserting a gene from bacteria or a virus into an organism where it would normally not be found. The purpose is to alter the genetic code in plants and animals to make them more productive or resistant to pests or farming techniques. Genetically modified organisms, more commonly known as GMOs, have been a controversial topic of debate for a number of reasons. The ethics behind genetically modified foods come into question due to an abundance of short and long-term effects from the process, many of which are still unknown today. It is unethical to genetically modify foods without proper government regulations and thorough research into the negative effects it poses upon human consumption and environmental health.

GMO labels are unnecessary because genetic modification is safe, beneficial, and regulated by the FDA. Genetic modification is not a new concept. Artificial selection and crossbreeding, both forms of genetic modification, have been used for centuries by scientists and farmers to obtain the desired traits of crops or animals (Kracht para 1). Moreover, no known risks have appeared from the consumption of GMOs or the genetic modification of crops.

● What are the pros and cons to genetic engineering?Pros and Cons of Genetic Engineering. Manipulationof genes in natural organisms, such as plants, animals, and even humans, is considered genetic engineering. This is done using a variety of different techniques like molecular cloning.

A disadvantage of artificial selection is stated on, “Lee County Students”, saying that “However, genetic modification is highly controversial.” This is a disadvantage because artificial selection is not fully proven to work, and there are not many studies that show it works easily. Another disadvantage of artificial selection is an unexpected result. There are many different outcomes of artificial selection and can be a surprise to the organism and owner, stated on “Pros and Cons of Artificial Selection”. A final disadvantage of artificial selection is shortened life. The offspring of an organism can have a lower than average lifespan due to artificial selection, said on “Pros and Cons of Artificial

Agriculture and fields related to agriculture contribute $2.7 Billion to the state every year. Sustaining future generations of agriculture are important, to show its importance, a convention is held to inform people about sustaining agriculture for future generations. During the convention, you will learn the many ways that agriculture is important and how what you do in your daily lives pertains to agriculture. Technology plays a big role in sustaining agriculture. New technology is always being invented in hopes of sustaining agriculture for future generations. Plant genetics play a part in the development of new technology. Understanding plant genetics can and will help the process of developing

Genetic engineering is the modification of an organism’s genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. Human beings ought to consider the pros and cons of genetic engineering before using it. It is a contentious topic because people have different views of weather genetic engineering is safe or not. This essay will look more on the advantages and disadvantages of genetic engineering.

According to Wikipedia, the official explanation for the term natural selection is: the differential survival and reproduction of individuals due to differences in phenotype. Artificial selection, on the other hand, is the process by which humans use animal breeding and plant breeding to selectively develop particular desired traits. These two were first fully expounded by Charles Darwin in On the Origin of Species, and are often put together for comparison. The two combined are now believed to be the main process that brings about evolution. In the following essay, I’m going to state out some differences by focusing on some pros and cons of both of them.

In the 1980’s, the first genetically modified tobacco and tomato crops were introduced and sold in China and have been, controversially, around ever since. Genetically modified organisms, or GMOs, according to the World Health Organization, are foods derived from organisms whose genetic material has been modified through genetic engineering. Since the first time genetically modified foods were introduced in the 1980's, there has been a debate on whether or not these alien foods are harmful to our health. According to Jeffrey Smith, author of the book Seeds of Deception, in Another Reason for Schools to Ban Genetically Engineered Foods, he states, “Gene insertion creates unpredicted, irreversible changes” (486). Clearly, the uncertainty for

This is because the better trait is produced by engineering genes which results in favoring one organism. Genetically modified organism can interrupt the natural process of the gene flow. A possible issue with the modified crop genes ending up in the soil which can produce new strands that can eventually attack the plant species and producing a new strand. Genes from the GM crops can spread to organic farm crops threating the diversity in agriculture. Due to cross pollination to non-gm plants, new hybrid strains are created. The artificial strand that comes from GM crops can potentially decrease the bio
