The Pros And Cons Of Natural Selection

Predation is a biological interaction between two organisms of different species in a community in which one acts as a predator and captures and feeds on the other, the prey. Predator-prey relationships keep animal populations in balance. When prey populations increase more food is available for predators, and they increase in number as well. An increase in predators triggers a decrease in prey populations. As prey populations decrease predator populations soon follow as their food supply diminishes. Organisms can evolve to enhance their ability to catch prey, or flee predators. Coevolution occurs in a predator-prey relationship when the prey evolves in response to pressures exerted by its predator. The predator then evolves in response to the changes in the prey (or vice versa). Inheritable adaptive traits evolve through natural selection, the process by which organisms that have developed favorable traits are capable of surviving and reproducing at greater rates, thus passing their adaptive traits to their offspring.

After reading through and reviewing the articles, one can see that there is a clear trend in the research being done that shows predominantly negative impacts selective breeding has on dogs. Health in selectively bred dogs is the top concern when dealing with ethics, due to the fact that in many cases lives are cut short and the quality of life is viewed as, to many, not worth living, which is seen as unfair to the dogs in an ethical viewpoint. From dog show judges to veterinarians, there are many known diseases in dogs that is the product of selective breeding, and although there have been attempt to fix these errors, the topic is still ongoing as hip dysplasia, breathing issues, and cardiac problems are still prevalent in certain purebreds.

consider the genetic code as a book, entire pages will be repeated in one species

Social Darwinism is the result of applying Charles Darwin’s theories of evolution to human society, and one of the forefront Social Darwinists was none other than William Graham Sumner. In general, the concept of Social Darwinism has many pros such as “breeding” out weakness and disease, supporting the strong, and encouraging the development of a more advanced society. It also as many disadvantages, however, such as a smaller gene pool, hindering the weak, and controlling who gets to have children. Using the writings of both Darwin and Sumner, these pros and cons will be explored to prove that the negatives of Social Darwinism outweigh the positives.

Thesis Statement: Charles Darwin shaped evolutionary Biology into the way we see it today with his writings on how genetic variations of species between generations, how climate and many other things can cause variations between species, and just his idea of survival of the fittest in The Origin of Species.

Eugenics is the science of using artificial selection to improve genetic features of the population. It is thought that improvement of the human race can be seen through sterilization of people who exhibit undesirable traits and selective breeding. Often called Social Darwinism, the concept was widely accepted during the time of World War I. It quickly became a taboo after World War II when Nazi Germany used it as an excuse for genocide. The thought of improving the human race by manipulating who is allowed to breed can either be appalling or compelling. There are a few appealing aspects to the act of eugenics. If eugenics were applied, the world could potentially see a decrease in disease, a rise in intelligence, and heightened physical aesthetic in humans. But, ethically it crosses many boundaries that have prevented this idea from going into world-wide effect in the past.

Evolution often selects traits that promote genetic diversity because genetic diversity boosts the chances that at least some members of the population will have a combination of traits that will allow them to survive and reproduce in a changing environment. Organisms that rely on asexual reproduction have virtually identical offspring, and they are successful in a stable environment; however, conditions rarely remain constant on Earth. Therefore, evolution favors traits that promote genetic diversity because the conditions on Earth are always changing, and genetic variability provides organisms a better chance of survival than organisms that do not have genetic variability.

When the word artificial comes to my mind fake thoughts run through me, like water runs down your throat. Artificial christmas trees, flowers, foods, anything artificial you can think of, almost everyone has it and has produced it. As you read this, do you have any idea what artificial means? Said on dictionary.com, artificial means produced by humans, not occurring naturally. For example, artificial selection would be taking a wild animal, such as a whale, living in the huge ocean and putting him/her in a place like Seaworld, where they don’t adapt to the environment well, and are not used to the resources and rules. As you can see there has been many deaths at Seaworld because the animals, such as Orca whales, can not adapt to the small warm environment after being in the huge ocean with their family for their whole life. As said on “Live Science”“A 3-month-old orca calf

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.

1.Evolution is a changing process of all life forms, a trial that makes life adapting its living environment for survival. For my perspective, the difference between natural selection and genetic drift is the way of selecting genes. Natural selective is depending on outer environment. In the contrast, Genetic drift happens more randomly during evolution time. For the way of natural selection’s is a kind of adaption for living. As natural environment continually changing, some of organism’s genes may more appropriately adapt living environment. Therefore, only can creatures which obtain these “better” genes survive during the period of evolution. However, genetic drift reduces the diversity of creature’s genes. When a amount of life forms have

Genetically modified animals involve the changing of the genetic information by adding or removing DNA sequences in an uncommon way that is not natural. Genetic modification aims to modify certain characteristics of animals and/or introduce new traits. Those traits include resistance of diseases and growth enhancement (Ormandy, Dale, & Griffin, 2011).

Biodiversity is the differences of life on earth or in a specific location. There are three domains that consist of life in the world: Bacteria, Archaea, and Eukarya. Bacteria and Archaea are both prokaryotes. Prokaryotes are single cell organisms that lack a nucleus in the membrane nor other specialized organelles. For Eukarya it consists of four kingdoms: Protists, Plants, Fungi, and Animalia. The domain consists of organisms with a cell nucleus and other organelles inside a membrane. With these seven kingdoms scientists have been able to edge closer to classifying all organisms in the world, and are exploring every day to find new organisms.

Is it worth it to have a society that discriminates and demonizes those who have a lower status in society? Would you like a society where the leaders claim that survival isn’t a right but a privilege that is earned? This is the world of Social Darwinism where people are considered either “weak” or “strong” but not equal. I would like to say that this kind of society would not be good as it would only highlight humanity’s shortcomings. Now, I would like to discuss the history behind this idea and how this society would operate in modern times.

The evolutionism-reationism debate has been going on for centuries among christians and scientists. However, creationism is said to have more logical proof of their points being the strongest.

There are 2 ways to look into evolution, it’s either by Red queen model or Court Jester model. The “Red Queen” model come from Darwin, it’s an evolutionary hypothesis which proposes that organisms must adapt, evolve, and survive to gain reproductive advantage. In a Red Queen world, the species diversity is depends primarily on body size, width of physiological tolerance, or adaptability. The Court Jester model is different from Red Queen model because evolution, speciation, and extinction rarely happen except in response to undeterminable changes in the environment. In a Court Jester model, species diversity depends on unfaithfulness of climate, landscape, and food supply. One can say that, the Red Queen is biotic, and The Court Jester is
