One standard deviation has a 68% probability and two standard deviations have a 95% probability.

Radiocarbon dating has had an enormous impact on archaeology around the world since it made it possible to date carbon and wood could be directly without dependence on characteristic artifacts or written historical records.

But as more dates became available, Egyptologists, who had hieroglyphic records back thousands of years, began to recognize that C-14 dates were generally too young.

They proved this by showing that C-14 dates of wooden artifacts with cartouches (dated royal names) did not agree.

When this method was first developed, a fairly large amount of carbon was necessary for dating but use of the AMS (accelerator mass spectrometer) today necessitates only a few milligrams for analysis.

odern archaeology is built upon the evolutionary assumption that man evolved from a stone age (lasting about 3.4 million years) to a bronze age (c.

The explanation was that the physicists had assumed that the amount of C-14 in the atmosphere had been constant, when in fact it had varied over time.

The solution came using dendrochronology (tree ring dating).

C is created in the atmosphere by cosmic radiation and is taken up by plants and animals as long as they live.
