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 of change, the chemical and structural similarities of related life forms, the recorded genetic changes in living organisms for many generations (O'Neill) and the geographic distribution of these related species.
Fossil remains of animals and plants in sedimentary rock deposit prove and serve as records of past changes that occur through time and of the numerous varieties of living things. They also suggest that gaps or missing links in evolution are due only to lack of recorded data (O'Neill).
Living things share the same basic chemical and structural characteristics and highly complex organisms with billions of cells evolved from single-celled organisms through division (O'Neill). Another evidence is that 99% of the proteins, carbohydrates, fats and other molecules of living things are composed of only 6 out of 92 most common elements and that they inherit specific genetic combinations from their parents.
Most remarkably, the numerous types of proteins in living things are composed of only 20 kinds of amino acids and have only one DNA code, attesting to the basic molecular unity of life. Furthermore, living things obtain energy for growth, repair and reproduction from sunlight, by photosynthesis or indirectly by eating green vegetation and other organisms that consume this vegetation.
Moreover, vertebrates, or animals with internal skeletons, share the same types of body structures, which they...
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
Evolutionary Development of the Horse The horse is a hoofed mammal, a subspecies of the family Equidae, that has evolved over the past 45 to 55 million years from a small multi-toed creature into the large single-toed animal that we know today. The fossil record of the horse is extremely complex and detailed, probably due to the fact that paleozoologists have managed to put together the most complete picture of the
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
Creationism: Is there any Credible Evidence to Support it? In the beginning God created the heavens and the earth." (Genesis 1:1) This quotation from the Bible plus numerous others from the religious books of various religions lead us to believe that man, the earth, and the rest of the universe were originally created by a divine force rather than having been created as a result of a "Big Bang" and subsequent
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 creationism. Evolution is usually held responsible for inducing immorality among its followers. This paper discusses the impact of believing in evolution on the behavior of student by describing both the evolutionary theory and its various effects. EVOLUTION AND STUDENT BEHAVIOR It is the belief about an individual's origins that sparks a debate evolution and creation. This is because not only does the belief about origins (and the consequent debate)
