The technique of comparing the abundance ratio of a radioactive isotope to a reference isotope to determine the age of a material is called radioactive dating.

For example, based on the primate fossil record, scientists know that living primates evolved from fossil primates and that this evolutionary history took tens of millions of years.

By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.

So the Pb isotope ratios measured in these rocks today must be interpreted before their U-Pb ages can be calculated.

Various methods have been devised to determine this initial or common Pb, but all involve making unprovable assumptions.
