Recommended: Advantages and disadvantages of natural and artificial selection

Artificial and natural selection are really the same process but one is driven by man and the other is driven by an organism's traits that allow them to survive and reproduce. Artificial selection is when mankind chooses certain traits in plants and animals and breeds to enhance that trait. Natural selection is also a process where traits are selected for, but that selection is based upon a trait that gives the organism a mating or survival advantage and this allows them to pass down the traits they possess.

Artifical Selection Doesn't Necessarily Make a Species More Fit for Survival
Since humans formed cultures based upon agricultural and the raising of animals for food, man has gradually understood that he could selectively breed organisms in order to enhance certain traits that were beneficial for man. However, such traits may not necessarily be beneficial for a species fitness in nature. An example of this would be in the current breeding of bulldogs.They are being selected by man to have large heads, which requires them to be born by cesarean section. This would obviously not be a trait selected for in nature, as it would decrease species fitness. Artificial selection actually can reduce the natural variation of …show more content…

If a giraffe with a slightly longer neck is able to reach food in high treetops when supplies are low, he or she will have a greater chance to survive and reproduce than one with a shorter neck.The shorter necked giraffes may die that season or not have the energy resources to produce offspring.Therefore, the trait of a longer neck may be passed on to the offspring and the gene pool of giraffe will gradually have more individuals with long necks. In order for natural selection to operate there must be a variation in traits in the

The interactions of Europeans outside of Europe increased steadily. With the discovery of vast non-European goods, their economic nature had been successful. Interaction between European and non-Europeans lasting from the late 1700s to early 1900s, attitudes greatly varied due to intellectual and cultural European trends that altered their point of view. European attitudes towards non-Europeans changed from cautious respect to a belief of superiority due to changes in intellectual thought inspired by nationalism, local dominion, and an idea of superiority over another nation. The rise of nationalism created a condescending and disrespectful European view towards non-Europeans in the time period of 1710-1910.

During early colonization Europeans felt that non-Europeans lacked knowledge but were still worthy of respect, later we see a shift to imperialism and a more strengthened view of European superiority. Europeans discovered new lands and created several instances of interaction between Europeans and non-Europeans lasting from the mid 1700s to early 1900s. Early interactions were widely influenced by Enlightenment ideals that created an attitude of respect from the Europeans to non-Europeans. However, European attitudes towards non-Europeans shifted from cautious regard to extreme feelings of superiority. This change was also brought on by ideas such as social Darwinism.

The Differences The novel The Natural by Bernard Malamud displays a tragic story about a man with many flaws show extraordinary skills in baseball, with a depressing ending of disgrace. The movie, however, displays the story of a respectable guy dealing with a few unlucky happenings while also showing his natural talent in the sport of baseball. The movie and the book have some big differences include Iris, who she is and her relation with Roy, Roy’s aspects, and the ending. The two works have clear differences that arguably change the story totally.

Long and medium neck giraffes will be able to get the food, but small neck giraffes are not going to be able to eat. Stabilizing selection means when genetic variation decreases as the population “equalizes” on a particular characteristic. An example for this selection is that there is a community of squirrels, they have to pass into trees and branches to get food. Big

How does the nature vs. nurture debate play a role in the social issue of alcoholism? First let’s define the meaning of nature, nurture and alcoholism as it pertains to this subject. Nature is defined as predetermined traits give to an individual at birth by their mother or father through their genetic makeup. We see these things every day in a person’s eye and hair color but it also can effect a person’s behaviors. Nurture on the other had is defined by the outside influences we all face throughout our life.

Selective breeding, or genetic engineering, is the process of breeding animals for specific qualities. Animals that are endangered are bred like this so the strongest can live on and repopulate the species. Farm animals, like pigs, chickens and cows, are bred specifically so the animal is fat, or produces the more milk or eggs than the average cow or pig. The selectively bred animal that I picked is the layer hen. Selective breeding has many pros and cons.

Natural Selection is the process by which organisms that contain an array of traits that have a survival advantage in an environment tend to leave more offspring that can survive to reproduce in the next line of their lineage. Natural selection is a process that is observable which falls into the category of operational science. In short periods of time different organisms were observed. New species have also been observed to prove this theory. “Speciation is the process of change in a population that produces distinct populations which rarely naturally interbreed due to geographic isolation or other factors”.

Biological vs. Social definition can be defined as what is actual verses what could possibly happen. On the lecture on Big Blue Button, Biological was described as “can” and Social definition was defined as “may”. One example to describe the meaning of Biological vs. Social definition could be referred to race. With biological, an example could be saying I can get a job because I finished school and got my degree. On the Social definition side, an example could be not getting the job you want because you are either Caucasian, African American, or another ethnicity.

It is pretty hard to unpack the influences in my life that have made me into the person I am today in a two-page paper. However, after thinking about it for a long time I could see a pattern of certain influences that kept coming up when I thought about who I am today and what made me into the person I am. After several unsuccessful attempts to rank the influences based on importance I decided merge them into two major themes. If I was to tell a complete stranger what the source of my skills, principles, and attitudes were; I would have to say they are attributed to my family and my extracurricular activities. These may seem like 2 very broad categories, but at the end of the day they are what shaped me into the person I am today.

Charles Darwin became famous for his theory of natural selection. This theory suggests that a change in heritability traits takes place in a population over time. This is due to random mutations that occur in the genome of an individual organism, and offspring can inherit these mutations. This was defined as the key to evolution, this is because random mutations arise in the genome of an individual. Until the 19th century, the prevailing view in western societies was that differences between individuals of species were uninteresting departures from their platonic ideals of created kinds.

BIOLOGY RESEARCH ESSAY There is great speculation around evolution. As we are continually in the process of discovering the history of human beings, there are many questions surrounding this topic. One very interesting question is why ancient ancestors of homo-sapiens evolved to walk upright like we do today. An apes’ DNA is astonishingly similar to that of a humans, (97% the same) and yet, our bones’ shapes and structure are very different.

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.

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.
