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.
This would be wood, plants, animals and of course humans.
Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers.
The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.
Nitrogen normally occurs in a seven proton, seven nuetron, nitrogen-14 state.
When it collides with an energetic neutron it becomes carbon-14, with six protons and eight neutrons and gives off a hydrogen atom with one proton and zero neutrons. Carbon-14 is an isotope of carbon, which exists only is small amounts in the environment (1 in one trillion carbon atoms is carbon-14).
