geochronologyDating and interpretation of geologic events in the history of the Earth. The classical technique of geochronology was stratigraphy, including faunal succession. Since the mid 20th century, radiometric dating has provided absolute age data to supplement the relative dates obtained from the fossil record. Radiometric dating is based on the principle that radioactive isotopes in geologic material decay at constant, known rates to daughter isotopes. See also carbon-14 dating. |

Topics that will be covered," the course description continued, "are the age of the earth, a worldwide flood, dinosaurs, pre-human fossils, dating methods, DNA, radioisotopes, and geological evidence. However, most groups seem to be retreating from their former definitive positions on this subject because of various technical discrepancies originating from assumptions made regarding the sequence dating methods themselves. Art historians express anxiety over absolute dating methods, not just because the results of such methods often contradict their own stylistic analyses, but also because science is accurate, science doesn't lie, the observations of science are conclusive, and scientific methods supposedly transcend human failings. |
