Natural Selection: Unraveling The Origins Controversy

302 Words2 Pages
Natural selection is organisms with traits that are best suited to their environment and are more likely to survive and reproduce. As stated in chapter 5 of Unraveling the Origins Controversy, “Natural selection is deemed the primary mechanism of non-random changes in the number of particular traits in a population” (David A. DeWitt, 2007). Some of the factors that limit natural selection are traits that are not heritable. Some examples are learned behaviors; diet induced traits, and behaviorally induced traits. Between non-genetic factors outside of the organism and genetic traits passed on by parents, the latter is most important. However, according to the article, “Racehorse Winning Secret Revealed” non-genetic traits can also be beneficial.

The cuneiform text of the “Legend of Sargon of Akkade” tells of a baby hidden in a basket coated with pitch and placed in the Euphrates River. As the basket carried down the river, the basket was opened by Akki, a royal gardener, who adopted the child and raised him as his own. Favored by the goddess Ishtar, the boy grew up and eventually became the ruler of Akkade, called Sargon, conquering lands near and far. While Sargon was late in reign, he commissioned the “Legend of Sargon of Akkade” for the future to read to preserve his military and leader accomplishments, as well as establishing the source of his legitimacy both to secure his legacy as a form of afterlife.

For Natural Selection to occur there must be some level of variation among the population that is heritable.

In this natural selection and genetics lab, a pair of alleles was randomly chosen from a cup of 100 alleles. There were 50 dominant and 50 recessive alleles. A pair of alleles was chosen randomly from the cup. The first time this was done all the organisms survived. The second time this was done the organisms that were homozygous recessive died due to the lack of an enzyme needed to digest grain.

Natural Selection Introduction: Natural Selection is the ability to survive and reproduce in a given environment. It is known due to evolution that has occurred over time and how mutation, migration, and genetic drift have changed. There is a variation in traits in animals, for example some birds have bigger beaks that can be used to feed on worms and bugs that are way underneath the river and lakes. Also there is a differential reproduction that occurs because not all animals can reproduce the same amount and there is a limit that the environment can support over time.

When a child is born and they develop characteristics, people usually look to their parents for similarities. If the parents do not share the same traits then they assume the sudden changes are caused by nature. Another example of nature taking its course is when children develop intellectual skills at a very young age and become successful. Developing these skills is not given to children by their parents but by chance. Epigenetics play a major role involving your genes.

For years people have been debating whether Nature or Nurture make up who we are and now we find out. Nature is our genetics what are parents have given us that make the color of our eyes or the color of our hair but that makes us up physically not mentally or emotionally. Nurture is the environment we grew up and how we adapted to the environment this is focused more on the mental and social level of who we are. Nurture is more Important than being that it is focused on the mentally a social levels. First, in the rat experiment at first the smarter rats did better than the dumb rats by a landslide but, when the were both given a better living environment they both performed exceptionally well.

Artificial selection is the process in which individuals are chosen whether or not to reproduce depending on whether they express desirable traits. This process is also known as selective breeding. Artificial selection is an expensive process used in domestic dogs, cats, horses and cattle to increase the frequency of desired traits. This essay will argue that selective breeding is not supported for three main reasons; firstly, there are the risk of inbreeding, secondly, the use of artificial selection lessens the amount of variations that exist in a gene pool and lastly, the quality of life is often reduced due to selective breeding.

Natural Selection is the long gradual process in which Biological traits either become more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. In Darwin’s work The Origin of Species he also mentioned evidence for the Theory of Evolution from his voyage around the world on The H.M.S. Beagle. The Origin of Species is probably the most influential work on evolutionary biology. The Origin of Species will help prove my thesis because it introduces the ideas that we base on evolutionary biology today.

The nature versus nurture argument is one of the oldest debates amongst psychologists. The debate concerns whether certain aspects of your personality are inherited or if you learn them from your surroundings. It has long been acknowledged that our hair, skin colour and certain diseases are governed by our genes. Other physical attributes if not determined, seem to be strongly linked to the genetic makeup of our parents. Height, weight and life expectancy are all correlated between related individuals.

Some of the traits become less notable dependent upon the environment the animal is placed in (Nurture)”. When observing a dog of a different breed one can see behaviour that can be identified as being specific to the breed. In mixed breed dogs the dominant genetic behaviour can be readily identifiable to a specific breed. Some dogs are very laid back, a child can pull on their ear and the dog just won’t react, this could be a genetic disposition. However if the same dog was beaten or traumatized in some way (Nurture) the dog may even bite the child.

Three different sides will be discussed in this paper. First is the theory of natural selection, often called the survival of the fittest. Natural selection as quoted by the Merrium Webster Dictionary is, “a natural process that results in the survival and reproductive success of individuals or groups best adjusted to their environment and that leads to the perpetuation of genetic qualities best suited to that particular environment.” For example there is a litter of cats. One of these cats is a lot faster than the other cats and is therefore able to get food easier.

Nature vs. Nurture Extra Credit The debate in psychology whether and to what extent our aspects of behavior are either genetic or learned characteristics has been going on for a long time. Genetic is the nature side of the argument. Learned refers to the nurture side of this long debate.

Nature and Nurture Influences on Child Development Karla White ECE 205: Introduction to Child Development Instructor: Alesia Lane October 2, 2017 Nature and Nurture Influences on Child Development Describe the relationship between nature versus nurture. The nature vs. nature debate is the scientific, cultural, and philosophical debate about whether human culture, behavior, and personality are caused primarily by nature or nurture. Nature is often defined in this debate as genetic or hormone-based behaviors. Our genes determine the different traits that we have, such as eye color, hair, ear size, height and other traits.
