Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology this usually requires what is commonly known as a dating method several dating methods exist, depending on different criteria and techniques, and. Absolute dating, with some reservation, is provided by dendrochronology, varve dating, thermoluminescence, potassium-argon dating, and, most important presently, radiocarbon dating some relative dating can be calibrated by these or by historical methods to give a close approximation to absolute dates -- archaeomagnetism, obsidian hydration.

To date fossils outside the range of carbon dating, researchers use indirect methods of establishing absolute fossil age explain how this could be done using radioisotopes with longer half-lives, such as uranium-238. Radioactive dating is not important in providing evidence for evolution radioactive dating can only provide indirect evidence for evolution radioactive dating can provide supporting evidence for evolution the easiest form of radioactive dating to understand is carbon 14 carbon 14 with a half life of 5,700 years can only be used to date the most recent fossils.
