Perhaps the most widely used evidence for the Theory of Evolution through Natural Selection is the fossil record.

The fossil record may be incomplete and may never fully completed, but there are still many clues to evolution and how it happens within the fossil record.

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.

In 1960, he was awarded the Nobel Prize in Chemistry for this work.

He first demonstrated the accuracy of radiocarbon dating by accurately estimating the age of wood from an ancient Egyptian royal barge of which the age was known from historical documents.

Though still heavily used, relative dating is now augmented by several modern dating techniques.Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element.Radioactivity, also known as radioactive decay, is a process by which a radioactive isotope loses subatomic particles (helium nuclei or electrons) from its nucleus along with usual emission of gamma radiation, and becomes a different element.After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.Geologists often need to know the age of material that they find.
