Amino acid dating: Physical structure of living beings depends on the protein content in their bodies.
The changes in this content help determine the relative age of these fossils.
To find their age, two major geological dating methods are used.
These are called relative and absolute dating techniques.
This Science Struck post enlists the differences between the absolute and relative dating methods.
Geological specimens that are unearthed need to be assigned an appropriate age.
The rate of decay of these elements helps determine their age, and in turn the age of the rocks.Absolute dating, also called numerical dating, arranges the historical remains in order of their ages.Whereas, relative dating arranges them in the geological order of their formation.The method of reading the order is called stratigraphy (layers of rock are called strata).Relative dating does not provide actual numerical dates for the rocks.
