¶ … evolution and natural selection is the addition of information. The process of evolution requires massive amounts of new information be added to an existing gene pool. What most people refer to as evolution is, in fact, natural selection. Natural selection occurs when genes that already exist in an animals' DNA, or sometimes on defective genes that have lost information (called mutation) are somehow altered. Neither process adds information to the gene pool so cannot be considered to be evolution. The evolutionary process is a slow and meticulous one and is preceded by numerous incidents of natural selection. True evolution is truly rare and takes place over the span of many years. Natural selection occurs far more frequently and can occur in the space of several generations. Natural field experiments are efforts by the scientific community to apply the scientific method to real life situations. This process allows scientists to test products, theories, and experiments that cannot be fully and adequately tested in a laboratory setting. Field experiments allow the same procedures that are used in the laboratory to be used on real life subjects. Field experiments have been used extensively for many years in some educational disciplines such as geology and anthropology but its use has taken on increased use in the other sciences and social sciences as well. The field of ecology is a natural for the use of field experiments. Field experiments allow ecologist to not only use manipulation as they would in the laboratory but also to witness the effects of their experimentation in a natural setting. Critics of the use of field experiments in the study of ecology argue that experimenters may alter the natural environment so severely as to make the findings irrelevant....
To counter-balance this possibility, some ecologists duplicate the experiments in the laboratory and in the field.
Evolution The book Why Evolution is True by Jerry Coyne presents a cogent case for evolution, a concept that can be controversial for some but accepted fact for others. This paper will work through the book -- the case that Coyne makes -- and offer reflections on my own journey of understanding the concept of evolution and its manifestation in the natural world. Understanding Evolution Evolution is not "fact," so much as a
Evolution Is True What Is Evolution? This chapter highlights the six elements that make up evolution: 1) growth/evolution; 2) gradualism; 3) speciation; 4) shared origins; 5) natural selection; and 6) nonselective evolutionary change mechanisms (Coyne, 2009). Of these, the foremost is the evolution concept itself, which implies genetic modification of any given species with time. To elaborate, over a number of generations, species of animals may transform into a rather different
Evolution be Taught in Schools? Introduction / Thesis (Part One) The debate between those that believe in creationism -- or "intelligent design," a refined offshoot of the creationism theory -- and those who believe in the science of evolution, spilled over into the schools in the United States many years ago. Conservative Christians and others who are in denial vis-a-vis Charles Darwin's research and theory argue that at the very least
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
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
