In evolutionary studies, absolute dating can be described as a method which scientists use to date any material that they find. Relative dating is a method in which scientists try to puts the geological events in a relative order. In absolute dating, the exact age of the rock will be calculated by the scientist. In relative studies, the scientist will try to place the rock in the best geologic time in which the rock might have existed.
The most common method for absolute dating is the method of radiometric dating. Radioactive minerals present in the rock act as geologic time which are determined by the scientists.
