Absolute Dating • Dating techniques are used in archeology to ascertain the age of old artifacts and a broad classification of these methods bifurcates them in relative dating and absolute dating • Relative dating comes to a conclusion based upon the study of layer formation of rocks.

We saw the word “ontology” already when talking about “the origin of how things became” and the different ontologies that religions and science have.

Paleontology looks at life in the past, and the most popular branch is dinosaurs.

Closely related human ancestors get their own subfield, paleoanthropology, and the dividing line paleontology and paleoanthropology is usually when they start walking on two feet.

Confirmed human ancestors get another field called archaeology, and the line between paleoanthropology and archaeology is usually set at anatomically modern Homo sapiens. For this class, we focus on paleoanthropology and use paleontology to give an early context.

It is possible to tell the number of years ago a particular rock or archeological site had been formed.

Two broad categories of classification methods are relative dating and absolute dating.

This type of dating employs many dating techniques like atomic clocks, carbon dating, annual cycle methods, and trapped electron method.

Dendrochronology is another of the popular method of finding the exact age through growth and patterns of thick and thin ring formation in fossil trees.

The most popular method of radio dating is radio carbon dating which is possible because of the presence of C-14, an unstable isotope of carbon.
