By the 1830's Adam Sedgwick and Roderick Murchison established a correlation between the various types of fossils and the rock formations in the British Isles.

It was found that certain fossils, now referred to as index fossils, were restricted to a narrow zone of strata.

The first major figure whose scientific views conflicted with the official position of the church was Nicolaus Copernicus, who published an anonymous work claiming that the sun, not the earth, was the center of the solar system.

(The traditional, earth-centered view was associated with a second-century Egyptian natural philosopher named Ptolemy.) Copernicus died (1543) before his work was widely enough known, or widely enough associated with him, to cause him personal problems.

It's just one of the tricks that have been used to make the work a little more precise. I believe he has confused the use of index fossils with evolution.

One creationist editor, who is more mellow than his unfortunate statement suggests, phrased the argument thus: Unfortunately the geologists date the rocks as the paleontologists tell them to. That passage might have come out of one of Henry Morris' books, except that Morris usually avoids crude slander. Hovind is not aware of the fact that by 1815 the broad outlines of the geologic column from Paleozoic times onward had been worked out by people who were mostly geologists.

Ever since the end of the Middle Ages (which coincides with the beginning of the Protestant Reformation in the early 16th century), some Christians have had problems accepting the teachings of science.

Free 5-day trial Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.

Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.

In radiometric dating, the decaying matter is called the parent isotope and the stable outcome of the decay is called the daughter product.

Since the half-life of carbon-14 is 5730 years, scientists can measure the age of a sample by determining how many times its original carbon-14 amount has been cut in half since the death of the organism.
