Fossil dating problems
Evolution places severe demands upon fossils used to support it. A fossil in an evolutionary sequence must have both the proper morphology shape to fit that sequence and an appropriate date to justify its position in that sequence. Since the morphology of a fossil cannot be changed, it is obvious that the dating is the more subjective element of the two items. Yet, accurate dating of fossils is so essential that the scientific respectability of evolution is contingent upon fossils having appropriate dates. Popular presentations of human evolution show a rather smooth transition of fossils leading to modern humans. The impression given is that the dating of the individual fossils in that sequence is accurate enough to establish human evolution as a fact.

Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles. Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon.

The Dating Gap
Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers. Carbon dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things. Carbon is a radioactive isotope of carbon. The half-life of carbon is approximately 5, years. The short half-life of carbon means it cannot be used to date fossils that are allegedly extremely old, e. The question should be whether or not carbon can be used to date any artifacts at all?
Smith is known as the Father of English Geology. Oxford Library.
In fact, I believe that the question of how long life has existed on earth is even more important than the question of whether life was created or evolved. You see, the theory of evolution has so many problems that most people find evolution hard to accept, and I don't think many people are led to question their faith because of it.
About Glenn Fink
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. While the number of protons and electrons in an atom determine what element it is, the number of neutrons can vary widely between different atoms of the same element. Nearly 99 percent of all carbon on Earth is Carbon, meaning each atom has 12 neutrons in its nucleus. The shirt you're wearing, the carbon dioxide you inhale and the animals and plants you eat are all formed mostly of Carbon Carbon is a stable isotope, meaning its amount in any material remains the same year-after-year, century-after-century. Libby's groundbreaking radiocarbon dating technique instead looked at a much more rare isotope of carbon: Unlike Carbon, this isotope of carbon is unstable, and its atoms decay into an isotope of nitrogen over a period of thousands of years. New Carbon is produced at a steady rate in Earth's upper atmosphere, however, as the Sun's rays strike nitrogen atoms. Radiocarbon dating exploits this contrast between a stable and unstable carbon isotope.
Emissions from fossil fuels may limit carbon dating
Love-hungry teenagers and archaeologists agree: But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes. Until this century, relative dating was the only technique for identifying the age of a truly ancient object. By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site. Though still heavily used, relative dating is now augmented by several modern dating techniques. Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon content.
Scientists are accused of distorting theory of human evolution by misdating bones
Radiometric dating , radioactive dating or radioisotope dating is a technique used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts.
Accuracy of Fossils and Dating Methods
In my last two articles I talked about carbon dating for formerly living things and general radiometric dating for minerals and the problems with both methods. The short answer is: From the time of the ancient Greeks, observers saw thousands of strata layers in the earth and hypothesized that each layer was deposited gradually over long periods of time. The problem is that you cannot simply look at a rock and tell what layer it belongs to. Layers repeat and are often out of order. Layers vary in thickness, are frequently missing altogether, and many of the same minerals are found throughout many layers.

Radiometric Dating Methods
The fossil record can give us large amounts of knowledge. But there are many other ways that the fossil record is incomplete or misleading. Scientists must keep these problems in mind when they are reading the fossil record to come to conclusions about dinosaurs and their lifestyles. Large, heavy bones are more likely to be preserved than small, lightly built bones. So, although small vertebrates usually outnumber large, fossils of small vertebrates are scarce. This might seem to suggest that big dinosaurs dominated the landscape and that there were fewer small animals. This was probably not the case.Determining the Age of a Fossil Using Carbon-14
