This evaluation of the rocks and fossils in relative dating is known as the biostratigraphy.

The absolute dating is the technique to ascertain the exact numerical age of the artifacts, rocks or even sites, with using the methods like carbon dating and other.

In radiometric dating, the radioactive minerals within the rocks are used to know about the age of the object or the sites.

Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods.

Paleontologists now apply sophisticated mathematical techniques to assess the relative quality of particular fossil successions, as well as the entire fossil record.

These demonstrate that, of course, we do not know everything (and clearly never will), but we know enough.

New discoveries have filled in the gaps, and shown us in unimaginable detail the shape of the great ‘tree of life’.

The discovery of means for absolute dating in the early 1900s was a huge advance.

The methods are all based on radioactive decay: The first radiometric dates, generated about 1920, showed that the Earth was hundreds of millions, or billions, of years old.

The absolute dating is more reliable than the relative dating, which merely puts the different events in the time order and explains one using the other.

Radiometric dating is another crucial technique through which the exact age can be obtained.

The rejection of the validity of fossils and of dating by religious fundamentalists creates a problem for them: Fossil sequences were recognized and established in their broad outlines long before Charles Darwin had even thought of evolution.
