Why is potassium argon dating useful for dating hominids

As a result, there is a changing ratio of carbon-14 to the more atomically stable carbon-12 involves actually counting individual carbon-14 atoms.

This allows the dating of much older and smaller samples but at a far higher cost.

Thus, to be considered as archaeological, the remains, objects or artifacts to be dated must be related to human activity.

Following death, however, no new carbon is consumed.

Progressively through time, the carbon-14 atoms decay and once again become nitrogen-14.

As an example Pinnacle Point's caves, in the southern coast of South Africa, provided evidence that marine resources (shellfish) have been regularly exploited by humans as of 170,000 years ago.

On the other hand, remains as recent as a hundred years old can also be the target of archaeological dating methods.
