While ^{12}C is the most abundant **carbon isotope**, there is a close to constant ratio of ^{12}C to ^{14}C in the environment, and hence in the molecules, cells, and tissues of living organisms. www.biology.arizona.edu/biomath/tutorials/Applications/**Carbon**.html www.biology.arizona.edu/biomath/tutorials/.../**Carbon**.html Carbon dating is based upon the decay of ^{14}C, a radioactive isotope of carbon with a relatively long half-life (5700 years).
