¶ … 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...
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 coloring of feathers in birds is brighter for males and fainter for females; this is also true…

Evolution "Creational critics often charge that evolution cannot be tested, and therefore cannot be viewed as properly scientific subject at all. This claim is rhetorical nonsense" (Stephen Jay Gould). Human life is both sacred and mysterious. From time before recorded history, human beings, both scientific and religious have tried to determine what it is exactly that gives life and by extension, can take life away. In ancient times, most people believed that
" The differences between Darwin and Lamarck's theories primarily stem from the second category, under content, dealing with how "organisms progress from 'lower' to 'higher' forms'" (Firenze 1997). The key difference between Lamarck's and Darwin's ideas occurs when a variation appears concerning this progression from lower to higher. Lamarck's position is that acquired characteristics arise after the environment changes. That is, a change in the environment will lead to a change
Countless fossils and remnants of ancient limbs (such as the legs found on a dolphin recently) continue to back up the theory of how animals evolved from other forms of life and other kinds of bodies. For instance, whales and dolphins (proven by DNA to be related) have the vestiges of legs within their sleek bodies and their front "fins" have bones that correspond to human hands, rather than
EVOLUTION What is evolutionary theory and what are causes of evolution and the evidence of evolution? The term 'evolution' evokes varied connotations. In simple and direct terms it is a process of change or development over a long period of time. Defined so, evolution can refer to any phenomena-- evolution of universe, evolution of human culture etc. -- that change over a period of time. However, in common parlance, evolution refers to
Evolution vs. Creationism Biological evolution or evolutionary biology is genetic change in a population occurring from generation to another (O'Neill 2002). All life forms evolve and continue evolving from earlier species, and these life forms include human beings. Most biological scientists concur that the earliest life forms on earth evolved from chance natural occurrences 3 1/5 to 4 billion years ago. They agree that evidence for evolution comes from fossil records
In conclusion, perhaps we should heed the words of Charles Darwin himself who before his historic voyage aboard the H.M.S. Beagle between 1831 and 1836 was a devout Christian and creationist -- "There is a grandeur in this view of life. Whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and
