Philip J. The American Biology Teacher 1 February ; 82 2 : 72— The recent discovery of radiocarbon in dinosaur bones at first seems incompatible with an age of millions of years, due to the short half-life of radiocarbon. However, evidence from isotopes other than radiocarbon shows that dinosaur fossils are indeed millions of years old. Fossil bone incorporates new radiocarbon by means of recrystallization and, in some cases, bacterial activity and uranium decay. Because of this, bone mineral — fossil or otherwise — is a material that cannot yield an accurate radiocarbon date except under extraordinary circumstances.
Rock of Ages, Ages of Rock
Lisle Oct 27, Geology , Origins , Physics. We are told that scientists use a technique called radiometric dating to measure the age of rocks. We are also told that this method very reliably and consistently yields ages of millions to billions of years, thereby establishing beyond question that the earth is immensely old — a concept known as deep time.
This apparently contradicts the biblical record in which we read that God created in six days, with Adam being made on the sixth day.
Most of the arguments made by creationists try to discount various dating methods used by scientists. One interesting theological argument, however.
The belief in the account of the creation of the universe as presented in Genesis. Some creationists consider the theory of creation described in Genesis to be a scientific account and the Big Bang theory and the theory of evolution to be false. Advocates of creation science have campaigned to have the biblical version of creation taught as a science in U.
The state of Arkansas passed a law requiring the teaching of creationism in public schools. In , the law was ruled unconstitutional by a federal judge who declared creationism to be religious in nature. A similar Louisiana law was overturned in In their defense, creationists have asserted such things as evolution is not a fact, it is just a theory. Some scientists, such as Carl Sagan, on the other hand, have asserted that evolution is a fact, not a theory.
Stephen Jay Gould claims that evolution is both a fact and a theory.

A progressive creationist, on the other hand, accepts the views of modern astronomy and geological dating methods that determine the Earth to be billions of.
Every religion in the world has its own version of the origins of life and matter. In Abrahamic religions, including Christianity, Judaism and Islam, these explanations rest on the premise that God created the universe and everything in it. This is the basic tenet of creationism in the West. In the United States, the public debate between Christian creationism and evolution , once considered dead in the wake of the Scopes Monkey trial, is back on its feet. Most people see evolution and the theory of natural selection as scientific staples; now, many supporters of creationism want their views to be accepted as a scientific theory known as creation science.
In this article, we’ll examine the different forms of Christian creationism, touch on creationist views in other religions and find out what’s fueling the controversy. Creationism is a blanket term incorporating all beliefs that the origins of the universe and life are attributable to supernatural or miraculous means. In Christianity, creationism states that God the Christian deity created the world and everything in it out of nothing.
Creationists believe that the account of the beginning of the world offered in Genesis , the first volume of the Old Testament, is the true account of the origins of all that we see around us.
Creationism vs radiometric dating
In my psychology courses, I cover evolutionary psychology. I am sometimes asked why I do not mention creation science, as an alternative. I have also been asked why the text books I use. This interactive web site has been created to address these questions. Is creationism based on religious beliefs or scientific facts? The text author says evolution is accepted as fact
dating methods, and that many scientists “worship at the altar of Darwinism.” These people are scientists, lawyers, philosophers, theologians, and politicians.
Evolution is a basic component of many aspects of anthropology including physical anthropology, archeology, cultural anthropology, and linguistics and is a cornerstone of modern science, being central to biology, geology, and astronomy;. The principles of evolution have been tested repeatedly and found to be valid according to scientific criteria. Evolution should be part of the pre-college curriculum; it is the best scientific explanation of human and nonhuman biology and the key to understanding the origin and development of life;.
Religious views are an important part of human cultures, and deserve a place in the pre- college curriculum, provided that they are not presented dogmatically or in a proselytizing context. A comparative, anthropological study of religion would not violate the Constitutional requirement of religious neutrality in the classroom. An anthropological understanding of religion would be helpful in resolving some of the perceived conflict between creationism and evolution;.
The Association respects the right of people to hold diverse religious beliefs, including those who reject evolution as matters of theology or faith. Such beliefs should not be presented as science, however;. Many succumb to this pressure, for lack of expressed support from scientists and other community members;. Therefore anthropologists are encouraged to use their knowledge both of evolution and of human social and cultural systems to assist communities in which evolution and creationism have become contentious.
Anthropologists should help the public and public officials understand that good science education requires that evolution be presented in the same manner as other well-supported scientific theories, without special qualifications or disclaimers, and that an understanding of religion and other cultural systems should be part of the education of each child.
Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow. 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.
In the first place, Creationists argue that methods of radiometric dating employ false assumptions. They continue by using special techniques of their own to assign.
Slideshows Videos Audio. Here of some of the well-tested methods of dating used in the study of early humans: Potassium-argon dating , Argon-argon dating , Carbon or Radiocarbon , and Uranium series. All of these methods measure the amount of radioactive decay of chemical elements; the decay occurs in a consistent manner, like a clock, over long periods of time.
Thermo-luminescence , Optically stimulated luminescence , and Electron spin resonance. All of these methods measure the amount of electrons that get absorbed and trapped inside a rock or tooth over time. Since animal species change over time, the fauna can be arranged from younger to older.

Creationists ultimately date the earth historically using the chronology of the Bible. With the discovery of radioactive dating methods, the ages of the rocks and.
Creationist’s Blind Dates. The standard scientific estimate is that the universe is about 15 billion years old, the earth about 4. It is important to recognize from the start that there are independent procedures for obtaining each of these estimates, and that the procedures yield ranges of values that overlap. In the case of the universe, estimates can be obtained from astronomical methods or considerations of nuclear reactions. Astrophysicists can measure the rate at which galaxies are receding and use these measurements to compute the time needed for the universe to expand to its present size.
A second, independent, astronomical method is to use standard techniques to measure some parameters of stars mass, luminosity, compositor, and surface temperature , from which a well-confirmed theory of the life histories of stars enables physicists to compute their. Finally, considerations of radioactive decay make it possible to calculate the time at which certain heavy elements were formed. These techniques are somewhat similar to the radiometric methods of dating rocks, which I shad consider in a little more detail.
For an excellent overview of the various ways of assigning an age to the universe, and an exposition of the radioactive decay method, see Schramm Although the clear consensus of physical techniques is that the universe is billions of years old, and although this result controverts the claims of at least some contemporary Creationists, the principal Creationist attack has been directed against the standard geological claim that the earth is about 4.
Two kinds of arguments are offered. In the first place, Creationists argue that methods of radiometric dating employ false assumptions. They continue by using special techniques of their own to assign to the earth an age of a few thousand years. Excellent and exhaustive explanations of the errors in Creationist arguments about dating methods have been given by Stephen Brush , and Brent Dalrymple
Experiential Thinking in Creationism—A Textual Analysis
Seventy years ago, American chemist Willard Libby devised an ingenious method for dating organic materials. His technique, known as carbon dating, revolutionized the field of archaeology. Now researchers could accurately calculate the age of any object made of organic materials by observing how much of a certain form of carbon remained, and then calculating backwards to determine when the plant or animal that the material came from had died. An isotope is a form of an element with a certain number of neutrons, which are the subatomic particles found in the nucleus of an atom that have no charge.
During the recent debate between Ken Ham and Bill Nye, the young earth creationist Ken Ham made the claim that some 90% of dating methods.
What the Theory of Evolution Says. In his pioneering work On The Origin of Species , Charles Darwin believed that scientists would find fossils showing transitions from one kind of animal to another. Darwin assumed that strata layers of sedimentary rock are thick, continuous, and old with the oldest records in the lowest layers and the youngest in the uppermost layers. Life forms would be preserved in those layers having the same age as the life forms; hence, similar histories of strata in different locations, species emergence, transition forms, and extinction records could be correlated.
Darwin was influenced by a geologist of his day, Sir Charles Lyell, who argued that the earth was quite old and that geology is explained by uniform gradual, not catastrophic, process currently observed. That is called uniformitarianism. However, Darwin argued that some geological changes occurred in agreement with 20 th century geologists and isolated species environmentally.
Creation 101: Radiometric Dating and the Age of the Earth
The only group of people who seem to dispute the dates in any significant fashion are Christians who argue for a 6, to 10,year-old Earth.
Creationism is the religious belief that nature , and aspects such as the universe , Earth , life , and humans , originated with supernatural acts of divine creation. The term creationism most often refers to belief in special creation ; the claim that the universe and lifeforms were created as they exist today by divine action, and that the only true explanations are those which are compatible with a Christian fundamentalist literal interpretation of the creation myths found in the Bible ‘s Genesis creation narrative.
From the 18th century onward, Old Earth Creationism accepted geological time harmonized with Genesis through gap or day-age theory , while supporting anti-evolution. Modern old-Earth creationists support progressive creationism and continue to reject evolutionary explanations. Mainline Protestants and the Catholic Church reconcile modern science with their faith in Creation through forms of theistic evolution which hold that God purposefully created through the laws of nature , and accept evolution.
Some groups call their belief evolutionary creationism. Less prominently, there are also members of the Islamic   and Hindu  faiths who are creationists. Use of the term “creationist” in this context dates back to Charles Darwin ‘s unpublished sketch draft for what became On the Origin of Species ,  and he used the term later in letters to colleagues. The basis for many creationists’ beliefs is a literal or quasi-literal interpretation of the Old Testament , especially from stories from the book of Genesis :.
A further important element is the interpretation of the Biblical chronology , the elaborate system of life-spans, “generations,” and other means by which the Bible measures the passage of events from the creation Genesis to the Book of Daniel , the last biblical book in which it appears. Recent decades have seen attempts to de-link creationism from the Bible and recast it as science; these include creation science and intelligent design.
Cross-checking Dating Methods: Tree Rings, Varves, and Carbon-14
Chapter 9. White, In order to believe the earth is more no more than years old requires the abandonment of all known geological dating methods. But the Biblical view of nature is that God not only initiated, but He continues to work in and through His creation. Ever since the 16 th century, investigators have found a world of fossilized animal and plant life buried in strata of the earth.
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.
You’ve got two decay products, lead and helium, and they’re giving two different ages for the zircon. For this reason, ICR research has long focused on the science behind these dating techniques. These observations give us confidence that radiometric dating is not trustworthy. Research has even identified precisely where radioisotope dating went wrong. See the articles below for more information on the pitfalls of these dating methods. Radioactive isotopes are commonly portrayed as providing rock-solid evidence that the earth is billions of years old.
Since such isotopes are thought to decay at consistent rates over time, the assumption is that simple measurements can lead to reliable ages. But new discoveries of rate fluctuations continue to challenge the reliability of radioisotope decay rates in general—and thus, the reliability of vast ages seemingly derived from radioisotope dating. The discovery of fresh blood in a spectacular mosquito fossil strongly contradicts its own “scientific” age assignment of 46 million years.
