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.

Nyerup's words illustrate poignantly the critical power and importance of dating; to order time.
Radiocarbon dating has been one of the most significant discoveries in 20th century science.
Desmond Clark (1979) wrote that were it not for radiocarbon dating, "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation" (Clark, 1979:7).
Writing of the European Upper Palaeolithic, Movius (1960) concluded that "time alone is the lens that can throw it into focus".
One way that helps scientists place fossils into the correct era on the Geologic Time Scale is by using radiometric dating.
Also called absolute dating, scientists use the decay of radioactive elements within the fossils or the rocks around the fossils to determine the age of the organism that was preserved.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.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."Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.
