Anthropologists can describe a people’s physical character, culture, and environmental and social relations.

Because the cosmic ray bombardment is fairly constant, there’s a near-constant level of carbon-14 to carbon-12 ratio in Earth’s atmosphere.

is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past.

It can be used on objects as old as about 62,000 years.

Archaeology has undoubtedly enriched mankind’s history like no other science.

There is a greater part of man’s unwritten past that archaeology has managed to unravel.

History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past.

Historians can tell what cultures thrived in different regions and when they disintegrated.

The dating process is always designed to try to extract the carbon from a sample which is most representative of the original organism.

In general it is always better to date a properly identified single entity (such as a cereal grain or an identified bone) rather than a mixture of unidentified organic remains.

Carbon-14 has a half-life of 5,730 ± 40 years— during the succeeding 5,730 years.

Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.

Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.
