Therefore it should come as no surprise that creationists at the Institute for Creation Research ICR have been trying desperately to discredit this method for years. They have their work cut out for them, however, because radiocarbon C dating is one of the most reliable of all the radiometric dating methods. This article will answer several of the most common creationist attacks on carbon dating, using the question-answer format that has proved so useful to lecturers and debaters. How does carbon dating work? Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen N into carbon C or radiocarbon. Living organisms are constantly incorporating this C into their bodies along with other carbon isotopes. When the organisms die, they stop incorporating new C , and the old C starts to decay back into N by emitting beta particles.
September Evolution theory explains how organisms have changed over time. The fossil fish Priscacara liops found in sediments dating from the Eocene epoch Scientific understanding requires both facts and theories that can explain those facts in a coherent manner.
Evolutionary psychology is a theoretical approach to psychology that attempts to explain useful mental and psychological traits—such as memory, perception, or language—as adaptations, i.e., as.
Introduction Evolution itself is simply the process of change over time. When applied to biology, evolution generally refers to changes in life forms over time. The Theory of Biological Evolution is most often associated with Charles Darwin, because it was Charles Darwin that proposed the mechanism of natural selection and accompanied that proposition with a large volume of empirical data providing evidence for biological evolution.
Darwin was not, however, the first person to propose an evolutionary explanation for the diversity of life on earth. In fact, evolutionary concepts about life date far back into history and arose in many different cultures. The Greeks developed a concept of evolution over 2, years ago that was basically equivalent to that of Charles Darwin’s, but the early Christians opposed the idea and destroyed all of the works that promoted it or any other naturalistic explanations for earthly phenomena.
Origin Mythology There are literally thousands of different mythological stories about the origin of the world and of life. There are several common themes in origin mythology, but there are many different means by which the universe, earth, life, and man have come into being throughout the various different origin myths.
By David Masci Are faith and belief in evolution necessarily at odds? According to Pope Francis , the answer is no. Catholics accept the idea of evolution in some form, a substantial percentage of American adults reject the scientific explanation for the origins of human life, and a number of religious groups in the U. Here are five facts about evolution and faith:
In spite of efforts in many American states and localities to ban the teaching of evolution in public schools or to teach alternatives to evolution, courts in recent decades have consistently rejected public school curricula that veer away from evolutionary theory.
But as they feed on smaller fish and shrimp, their mouths begin to accumulate food debris and parasites. Lacking recourse to a toothbrush, how is such a fish going to clean its teeth? For several kinds of fish, the answer is a visit to the local cleaning station. These are special areas usually marked by the presence of certain shrimp and small, brightly colored fish, such as wrasses and gobis.
Often fresh from chasing and eating other small fish and shrimp, a predatory fish may periodically swim over to take his place in line literally! When his turn comes, he opens his mouth wide, baring the vicious-looking teeth. You might suspect, of course, that such a sight would frighten off the little cleaner fish and shrimp. Into the jaws of death swim the little cleaners. Now even a friendly dog will sometimes snap at you if you try to pick off a tick, and it probably irritates the big fish to have a shrimp crawling around on its tongue and little fish picking off parasites in the soft tissues of the mouth.
But the big fish just hovers there, allowing the cleaners to do their work. It even holds its gill chamber open so that the shrimp can crawl around on the gill filaments picking off parasites! At the end of all this cleaning, the second miracle occurs. When the cleaning is done, the big fish lets the little cleaner fish and shrimp back out again. Then the big fish swims off—and begins hunting again for little fish and shrimp to eat!
Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information.
As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods.
This is a review of evolution and creation doctrine. This site exposes poor science and assumptions associated with evolutionary theory, and presents compelling scientific evidence for Divine Creation—evidences in the fields of physics, biology, geology, and many other areas of science.
Sexiness Far from being conditioned to regard these things as important, Dunbar argued that men and women had evolved these preferences over millions of years of evolution. These were crucial qualities that enhanced the fitness of children, and, lest we forget, children are the key to the survival of our species. What hidden messages do we send the opposite sex? Pregnancy and breast-feeding place great stress on a mother, so females make the biggest investment in reproduction.
This is why women are choosier about their partners than men, with something women being the choosiest of all. This big parental investment also explains why women seek males who are willing to stick around and provide for children. Diamonds are a girl’s best friend But evolutionary theory tells us that resources should be just as important to women, if not more so.
Roman poet Lucretius, intellectual heir to the Greek atomists, believed its formation must have been relatively recent, given that there were no records going back beyond the Trojan War. The Talmudic rabbis, Martin Luther and others used the biblical account to extrapolate back from known history and came up with rather similar estimates for when the earth came into being.
Within decades observation began overtaking such thinking. In the s Nicolas Steno formulated our modern concepts of deposition of horizontal strata.

Related link pages Human Evolution theory Charles Darwin, pictured – left – as a young man , whom many people consider to have been the originator of Evolutionary Theory as applicable both to animal life generally and to Humanity in particular, actually shares with Alfred Russel Wallace the attribution for independent development of Modern Evolutionary Theory. Neither of them were to be the first to go so far as to explicitly take the step of subjecting Mankind to Evolutionary Theory speculations.
Darwin, born in into quite a comfortable background as the son of a well-regarded and prosperous doctor based in Shrewsbury, England, was an avid beetle collector in his teenage-years who abandoned medical studies after being appalled by the sufferings of patients undergoing the surgical techniques of the day, without relief from anaesthetics , and then entered Christ’s College, Cambridge, with the view of becoming a country parson. In those times it was quite accepted for clergymen to interest themselves in Natural History as part of God’s creation.
Whilst at Cambridge his interest in Natural History led to informal contacts with professors of Botany and Geology and, through these contacts, to an invitation to join HMS Beagle on an exploratory voyage to South America and beyond as a geologist. This invitation arrived just as Darwin had completed his university degree course and effectively postponed his actually becoming ordained as a clergyman. During this voyaging on HMS Beagle , however, Darwin lost his faith and also emerged from it as a recognised man of science due to the wider publication of certain learned papers he had sent home to friends and acquaintances.
Before the scientific era, people often made up imaginative stories to explain what they saw in the world. The scientific method changed that by requiring rigorous experimentation to test hypotheses and determine what is real. With the Theory of Evolution, people are back to making up imaginative stories. The primary advantage of complete metamorphosis is eliminating competition between the young and old.
Human evolution. Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.
Other problem-solving techniques Concisely stated, a genetic algorithm or GA for short is a programming technique that mimics biological evolution as a problem-solving strategy. Given a specific problem to solve, the input to the GA is a set of potential solutions to that problem, encoded in some fashion, and a metric called a fitness function that allows each candidate to be quantitatively evaluated. These candidates may be solutions already known to work, with the aim of the GA being to improve them, but more often they are generated at random.
The GA then evaluates each candidate according to the fitness function. In a pool of randomly generated candidates, of course, most will not work at all, and these will be deleted. However, purely by chance, a few may hold promise – they may show activity, even if only weak and imperfect activity, toward solving the problem. These promising candidates are kept and allowed to reproduce. Multiple copies are made of them, but the copies are not perfect; random changes are introduced during the copying process.
These digital offspring then go on to the next generation, forming a new pool of candidate solutions, and are subjected to a second round of fitness evaluation. Those candidate solutions which were worsened, or made no better, by the changes to their code are again deleted; but again, purely by chance, the random variations introduced into the population may have improved some individuals, making them into better, more complete or more efficient solutions to the problem at hand.
Again these winning individuals are selected and copied over into the next generation with random changes, and the process repeats. The expectation is that the average fitness of the population will increase each round, and so by repeating this process for hundreds or thousands of rounds, very good solutions to the problem can be discovered. As astonishing and counterintuitive as it may seem to some, genetic algorithms have proven to be an enormously powerful and successful problem-solving strategy, dramatically demonstrating the power of evolutionary principles.
Genetic algorithms have been used in a wide variety of fields to evolve solutions to problems as difficult as or more difficult than those faced by human designers.
Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years. One of the earliest defining human traits, bipedalism — the ability to walk on two legs — evolved over 4 million years ago.
Other important human characteristics — such as a large and complex brain, the ability to make and use tools, and the capacity for language — developed more recently. Many advanced traits — including complex symbolic expression, art, and elaborate cultural diversity — emerged mainly during the past , years. Physical and genetic similarities show that the modern human species , Homo sapiens, has a very close relationship to another group of primate species, the apes.
The theory of evolution has three basic parts: 1) it is possible for an organism’s DNA to change or mutate; 2) the change is harmful, beneficial, or neutral; and 3) after a long period of time, the mutations cause new species to form.
Are you sure you want to delete this answer? Yes Sorry, something has gone wrong. I too am shocked at the amount of misunderstanding and especially the amount of animosity. I know many esteemed scientists including anthropologists and geologists that have no problem being religious and believing in evolution. If you search the internet you will find many websites giving completely non-factual descriptions of how istopic dating works and using the small amount of uncertainty to claim it refutes all sorts of science.
I have even seen attempts at disproving the sedimentary record of the Grand Canyon using this. Never mind that these self-described experts have no qualifications to evaluate these things. In my opinion they are motivated by greed and not altruism. Debunking science seems to have become a cottage industry for what I consider pseudo-religious crackpots.
This is circular reasoning: Evolutionists position rocks in the Standard Geological Column by the stage which their index fossils represent in the presumed evolution of life. Thus the Standard Geological Column reflects evolutionary assumptions but does not prove them. The alleged evolutionary ages of rock strata do not always match the alleged evolutionary ages of some of the fossils they contain.
Supposedly younger strata sometimes contain supposedly older fossils. Supposedly older strata sometimes contain supposedly younger fossils.
Prior to the availability of radiometric dating, and even prior to evolutionary theory, the Earth was estimated to be at least hundreds of millions of years old. Radiometric dating has simply made the estimates more precise, and extended it into rocks barren of fossils and other stratigraphic tools.
This article will explain how carbon dating is supposed to work and then show you the serious flaws with this process. It is derived from a transcript of Dr. His videos and materials are not copyrighted. Carbon dating was not invented until When the schools started to teach that the earth is billions of years old, back in , the reasoning was not because of carbon dating. Carbon dating had not even been thought of yet. Billions of years are needed to make the evolution theory look good.
Without billions of years to hide in, the theory looks absolutely ridiculous. The geologic column is where it all started. The earth was divided up into layers. Each layer was assigned a name, an age, and an index fossil.
It is simply not true. Actually, it is just a fairy tale for adults based on ancient pagan religious philosophy that hundreds of millions of people around the world choose to believe with blind faith. When asked to produce evidence for the theory of evolution, most adults in the western world come up totally blank. This kind of anti-intellectualism even runs rampant on our college campuses.
If you doubt this, just go to a college campus some time and start asking students why they believe in evolution. Very few of them will actually be able to give you any real reasons why they believe it.
Dr. Jonathan Wells, a molecular biologist who has two Ph.D.s and who is not a Christian, examines evolutionists top ten evidences for evolution (e.g., the peppered moth, Haeckel’s embryo drawings, and the Miller-Urey experiment) and demonstrates how all of them are misrepresented and misused to support Darwin’s theory of naturalism.
General overview The evidence for evolution Darwin and other 19th-century biologists found compelling evidence for biological evolution in the comparative study of living organisms, in their geographic distribution, and in the fossil remains of extinct organisms. The amount of information about evolutionary history stored in the DNA and proteins of living things is virtually unlimited; scientists can reconstruct any detail of the evolutionary history of life by investing sufficient time and laboratory resources.

The following sections identify the most productive of these sources and illustrate the types of information they have provided. The fossil record Paleontologists have recovered and studied the fossil remains of many thousands of organisms that lived in the past. This fossil record shows that many kinds of extinct organisms were very different in form from any now living.
