Age of fossils in the past was generally determined by radiocarbon method and other methods involving radioactive elements found in the rocks. More precise methods, which were used recently and led to the revision of the evolutionary periods for different groups of organisms, includesA. study of carbohydrates/proteins in fossilsB. study of condition of fossilisationC.

Answer» Correct Answer - C
Electron Spin Resonance (ESR) measures number of c~argcs occupying deep traps in crystal band gap. The basic principle of ESR is same as those for hm1inescence, i.e. electrons become trapped and stored as a result of ionisino· b radiations, e.g. dating of tooth enamel
