The Circularity of Fossil Dating (Index Fossils)

Evolutionism is an ancient philosophy which may be traced all the way back to the Garden of Eden. The Greeks were writing the first formal theo ries of evolution 2, years ago. In three books of the New Testament Romans 1; Acts 17; 2 Peter 3 two Apostles of the First Century Church were dealing with the scientific aspects of the various theories of evolution that they had to deal with at that time. In Chapters 17 and 21 of the Book of Judges people are saying that if there is no God then we may do whatever we wish.

Deep Core Dating and Circular Reasoning

Creationists have long insisted that the main evidence for evolution — the fossil record — involves a serious case of circular reasoning. That is, the fossil evidence that life has evolved from simple to complex forms over the geological ages depends on the geological ages of the specific rocks in which these fossils are found. The rocks, however, are assigned geologic ages based on the fossil assemblages which they contain. The fossils, in turn, are arranged on the basis of their assumed evolutionary relationships.

Thus the main evidence for evolution is based on the assumption of evolution.

And yet, there is really no scientific reason proving that radiometric dating is correct, and Of course, the fossil dates depend on the assumption of evolution. classic illustration of circular reasoning.5 Grand Canyon Dating Creationists have.

Earth Science Stack Exchange is a question and answer site for those interested in the geology, meteorology, oceanography, and environmental sciences. It only takes a minute to sign up. I have heard the claim by creationists that geologists date rocks by the fossils they contain and date fossils by the rocks in which they are found. This supposedly invalidates radiometric ages because they are a result of circular reasoning.

Is this statement purely wrong, or is there some truth to it? Yes, there is some amount of circular reasoning in the statement: ” geologist date rocks by the fossils they contain and date fossils by the rocks in which they are found “. However, that statement does not fully describe how geologists date rocks or fossils. Dating rocks by fossils is a branch of geology called ” biostratigraphy “. This is a non-absolute and a relative method of dating.

Fossil dating circular reasoning. What is a commercial example of a circular reasoning?

How are geologic column used in relative dating Then try to date sedimentary rock. When they use relative dating is different areas. When geology first proposed Relative age — the geologic column was developed when they compare relative ages of dinosaurs. Interpret the principles geologists use the same principle used primary structures to it only igneous rocks, the describe the geologic record.

[You date the fossils by knowing the ages of the rocks that they are found in.] Glenco, Biology, , p. [Emphasis added]. The use of circular reasoning by.

Even many evolutionists ruefully admit that this charge is undeniable with regard to the circularity invoked in dating rock layers. Some of the following quotes are as cited in Morris, and Snelling, The series of quotes begins with a vivid illustration of this circular reasoning in action. In some cases darwinists have recognized circularity as a typical problem in evolutionary models and worked to avoid it. This time interval was from million years ago.

Strangely, little effort has been made to test this assumption. This failure leaves the method vulnerable to circularity. Scientists have determined the relative times of appearance and disappearance of many kinds of organisms from the location of their fossils within the sedimentary rock layers.

How Old Is That Fossil (in the layer)?

However, there is not one formation that contains all species of plants and animals together, but instead many different layers containing many different similarities of species that appear to change over time. If the fossil record looked like ICR claims, then uranium pdf never would have been found to begin with. You might argue that Scientists should date the fossils using Carbon dating like they do other more recent fossils.

Formula dating does not work for older rocks. Carbon is absorbed by living similarities from the atmosphere.

of circular reasoning when the resulting estimates are used to infer ages of biogeographic events. I argue that fossil-based dating is a superior alternative to.

No human investigation can be called real science if it cannot be demonstrated mathematically. After another years of scientific discovery, it makes even less sense today. Why, then, have recent-creationists taken up such an indefensible position? Presumably because, just as falling mountaineers will grab at an icicle, they feel that any explanation of the geological evidence is better than none at all. For their only alternative escape-route is even worse, as we shall now see. As chapter 5 mentioned, the only intellectual in the mid-nineteenth century to attempt a logical defence of recent-creationism was Philip Gosse.

He even created fossils to deceive unbelieving geologists. Gosse received little support. The idea that God set out to deceive people was repulsive to most nineteenth-century believers.

26 Circular Reasoning

This is the fourth such addition and it primarily concerns an area of intense concern by young-Earth creationists: the geologic column. There are a number of fairly obvious reasons for this concern on their part. Geology was, after astronomy, one of the first sciences to be organized as a professional study of nature along modern lines. It has a rich and extensive history of success in both increasing our knowledge of the world and proving its worth with many practical applications.

In short, it works in obvious and easily demonstrable ways.

Molecular dating has gained ever-increasing interest since the molecular clock hypothesis was proposed in the s. Molecular dating provides detailed temporal frameworks for divergence events in phylogenetic trees, allowing diverse evolutionary questions to be addressed. The key aspect of the molecular clock hypothesis, namely that differences in DNA or protein sequence between two species are proportional to the time elapsed since they diverged, was soon shown to be untenable.

Other approaches were proposed to take into account rate heterogeneity among lineages, but the calibration process, by which relative times are transformed into absolute ages, has received little attention until recently. New methods have now been proposed to resolve potential sources of error associated with the calibration of phylogenetic trees, particularly those involving use of the fossil record.

The use of the fossil record as a source of independent information in the calibration process is the main focus of this paper; other sources of calibration information are also discussed. Particularly error-prone aspects of fossil calibration are identified, such as fossil dating, the phylogenetic placement of the fossil and the incompleteness of the fossil record.

Methods proposed to tackle one or more of these potential error sources are discussed e. In conclusion, the fossil record remains the most reliable source of information for the calibration of phylogenetic trees, although associated assumptions and potential bias must be taken into account. The use of DNA sequences to estimate divergence times on phylogenetic trees molecular dating has gained increasing interest in the field of evolutionary biology in the past decade.

A Quick Case of Circular Reasoning in Evolutionary Biology

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.

The rocks are dated by the fossils and the fossils are dated by the rocks. Circular By doing so, we are guilty of circular reasoning if we then say the fossil record.

Circular Reasoning Before we look at the geologic column, we need to learn how to recognize a faulty logical process known as circular reasoning. In circular reasoning, Statement A is used to prove Statement B is true. Then the truth of Statement B is used to establish the truth of Statement A. This form of reasoning is invalid because it can be used to reach opposite conclusions regardless of the truth of the facts.

Scientists had formerly dated both the limestone and sandstone to be about 1. We know, for example, that the multilegged sea animals called trilobites were abundant from Cambrian to early Devonian times to million years ago-and continued until the Permian-up to million years ago.

Geologists going round in circles!

At the very least we would expect random fluctuations if the radiometric methods were totally at sea. Meanwhile, as if nature intended to add insult to injury, the colorations were becoming more and more distinct as the years rolled by! We also assume that nuclear decay rates do not change over time. It only exists in the textbooks and in the minds of those who believe it.

When some Christians first consider the possibility that Earth might have a much longer history than a few thousand years, they face a daunting challenge. Conventional scientists claim that dating methods are robust and reliable, but young-earth advocates insist that all are based on untestable assumptions and circular reasoning. Without the tools or expertise to independently evaluate the competing claims, many Christians default to the young-earth view, assuming there must be scientific justification for the young-earth claims.

For those of us who actually use these dating techniques, it is equally challenging to find ways to communicate the reliability of these methods in an understandable way. Fortunately, the availability of new experimental data is starting to make this task easier. We offer an example here of how independent dating methods can be combined to test assumptions and verify conclusions. Much more detail on this can be found in our recently published article in Perspectives on Science and Christian Faith.

The thin darker lines grow during winter or dry seasons, and the thicker, lighter rings during the summer or rainy seasons. So each pair typically represents one year.

The first form of circular reasoning in evolutionary theory surrounds the fact that, in relative dating, the ages of fossils are determined by the.

There are a whole lot of people out there probably the majority that believe, unequivocally, that scientists are capable of dating rocks, fossils, and the earth with a reasonable amount of certainty. So, when we hear of alternate views- such as young earth creation in which the earth is somewhere in the neighborhood of 7, years old based on Biblical chronologies- it sounds completely ridiculous to us. I mean, our middle school science books explained that scientists have methods to calculate absolute dates within an acceptable range with astounding accuracy.

It is declared- the evidence has spoken and it proclaims ages in the billions of years. As a Bible believing Christian, this leaves you with one of two options. Either the creation account in the Bible cannot be taken literally or these scientific dating methods are erroneous. For a look at the theories we Christians have come up with you can check out my article What in the World Happened Between Genesis and ? For example, embracing evolution as Biblical means that there could not have been a literal Adam and Eve- just think about the ramifications of that on the rest of the Bible.

In our newly altered reading and understanding of the text, what else do we end up compromising on? So, what about that second possibility? Could the problem actually be with our scientific dating methods? The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results. Sometimes only one method is possible, reducing the confidence researchers have in the results.
