This technique relies on the property of half-life.

Half-life is defined as the time it takes for one-half of a radioactive element to decay into a daughter isotope.

Relative age dating also means paying attention to crosscutting relationships.

Say for example that a volcanic dike, or a fault, cuts across several sedimentary layers, or maybe through another volcanic rock type.

One way that helps scientists place fossils into the correct era on the Geologic Time Scale is by using radiometric dating.

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.

The half-lives of several radioactive isotopes are known and are used often to figure out the age of newly found fossils.

Different isotopes have different half-lives and sometimes more than one present isotope can be used to get an even more specific age of a fossil.

The original atom is referred to as the parent and the following decay products are referred to as the daughter.

For example: after the it forms a component of all organic compounds and is therefore fundamental to life. Libby of the University of Chicago predicted the existence of carbon-14 before it was actually detected and formulated a hypothesis that radiocarbon might exist in living matter.
