    Dating method based on rate of decay of radioactive isotopes

    The latest high-tech equipment permits reliable results to be obtained even with microscopic samples.Radiometric dating is self-checking, because the data (after certain preliminary calculations are made) are fitted to a straight line (an "isochron") by means of standard linear regression methods of statistics.Here is one example of an isochron, based on measurements of basaltic meteorites (in this case the resulting date is 4.4 billion years) [Basaltic1981, pg. Skeptics of old-earth geology make great hay of these examples.

    As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils.

    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.
