The first and most serious is that any type of modification will produce a certain type of outcome. While it is true in the most general sense that helpful modifications are more likely to be retained, it is imperative to keep in mind that significant mutations to an organism are typically fatal, and that most genetic mutations that yield living organisms either cannot produce viable offspring or have an insignificant or slightly negative effect. Hence, pure quantity of variance within a species is meaningless, and the big decisions fall to fate: is species X capable of adapting to cataclysmic event Y? While the ability to adapt to diverse conditions is helpful, no significant change will occur in a species without...
Significant alterations, as previously noted, are typically fatal or incidental. Even if they are beneficial, they may not be beneficial at the time, as of a wolf that develops gills. This may be the reason for punctuated equilibrium; the tendency of evolution to progress very quickly in short periods of time, and then slow down incredibly. Cataclysm Y has the capability of isolating a very small group of organisms that are capable of adapting to resulting conditions, thus modifying the entire population without the necessity of waiting on natural selection to perform its slow miracles.
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
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
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
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
Charles Darwin is one of the founding fathers of psychology. Charles Robert Darwin was born in Shrewsbury, England on February 12th, 1809 and died on April 19th 1882 ("Wikipedia"). Darwin's was the grandson of Erasmus Darwin who was an intellectual figure in the history of science. His father was a well respected, successful physician. Charles Darwin comes from a line of intellectual men and was expected to do great things.
" The article also discusses the scientist John Tyndall, who with others in the British Advancement for the Society of Scientists, strongly supported Darwin. If it is admitted that matter has power attributed to it, where did it get that power? There can only be one answer, or the existence of a Devine Being. Similarly, if it is assumed that matter has developed into form and life, it regulates its procedure
