In relative dating, fossils are dated according to the depth at which they were buried. The fossils which are buried deep inside the earth are more ancient. While in the absolute dating, isotopes of carbon are used for dating fossils. The absolute dating is more precise than relative dating because it tells the exact age of the fossils. Both are ultimately based on the fossils found in the strata.
The timeline established by the theory of Darwinian evolution ultimately determines the age of fossils found in any given strata. The law of superimposition that the oldest fossils are found on the bottom is superseded by the law of decent with modification that the simplest fossils are the oldest and the youngest fossils are the most complex.
This is the basis of relative dating. Fossils Out of Sequence Palaios June page "We define stratigraphic disorder as the departure from perfect chronological order of fossils in a stratigraphic sequence, in which an older fossils occurs above a younger one. Pragmatism verus Materialism American Journal of Science Jan page Fossils date rocks not vice[versa and that's that. Absolute dating is based on radioactive decay half lives. All radioactive substances are found in igneous rocks except Carbon 14 which is only used to date fossils less than 50, years old.
As igneous rocks do not contain fossils, absolute dating can only be used to date the strata above or below the fossil bearing strata. This means that absolute dating is basically the same as relative dating as it is based on the law of superimposition the most recent rocks are higher in the geological column.
So a rock above a strata dated by radioactivity must be younger than the date obtained by radioactivity.
Ultimately fossils are dated using Darwinian evolutionary theory. Relative and absolute dating are dependent on the fossils and used to support the conclusions of the Darwinian order of descent with modification. How does absolute dating differ from relative dating?
New Scientist Nov 10 page Both absolute dating and relative dating are determined by the evolutionary timeline and are used to support the evolutionary timeline. This is the basis of relative dating Fossils Out of Sequence Palaios June page "We define stratigraphic disorder as the departure from perfect chronological order of fossils in a stratigraphic sequence, in which an older fossils occurs above a younger one.
