After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.
Historians can tell what cultures thrived in different regions and when they disintegrated.

Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.
Anthropologists can describe a people’s physical character, culture, and environmental and social relations.
Love-hungry teenagers and archaeologists agree: dating is hard.But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes.
