Evolution and Darwin Term Paper

Excerpt from Term Paper :

Evolution: Darwin

The purpose of this work is to explore the "Theory of Evolution" as set forth by Darwin and to further explore what is termed as "natural selection" as well as that of "artificial selection." This paper will further examine Darwin's Theory as to the workings of evolution as well as exploring exactly how natural selection works to produce evolution.

Finally, the role of individual genetic variations in relation to evolution and natural selection will be researched. The evolving of traits in species will also be examined as well as the applicable use of those theories.

Having first traveled throughout the world, on a ship, exploring both land and water, in the role of a "Naturalist," and having observed the wonders of the Andes and witnessed the result of Chilean earthquakes, crossed hundreds of miles, trekking through unknown regions, Charles Darwin, returned to England.

Darwin continued to study and after having read "The Principle of Population" written by Thomas Malther, Darwin then explained why evolution could and in his opinion had occurred.

I. Principles of Evolution:

The principles of evolution are as follows:

i. Variation is an existing factor among species.

ii. Adverse factors such as scarcity of resources leads to species competing for resources with some surviving and others dying.

iii. Having advantageous variations may cause a species to be more likely to not only to survive but also to reproduce.

III. Natural Section -- Artificial Selection:

"Natural Selection" so termed by Darwin, is the name given to the process by which a species survives because of favorable "variations." Darwin termed this type of survival to be "adaptive radiation." Survival through the process of adaptive radiation is "Divergent" in that two of more related species gradually became less and less alike.

IV. Biological Adaptation:

The three basic types of biological adaptation are:

1. Chance and Necessity: "Fundamental principles that living systems owe their properties to an interplay between random events and consistent, predictable processes. (Example: random asteroid impacts, random mutations)

2. Variation: This is the evolutionary biologists main point of study. There are no fixed properties in this process.

3. Biological Diversity: This is a comparative study of the evolution of collective species.

Natural selection could be demonstrated in the prehistoric features of birds that have been proven relation to the reptilian species. The…
