Because this break down occurs at a known rate it is theoretically possible to compare the amount of regular carbon and the amount of radioactive carbon and estimate just how long an organism has been dead.
Unfortunately, we aren't able to reliably date artifacts beyond several thousand years.
Scientists have tried to extend confidence in the carbon dating method further back in time by calibrating the method using tree ring dating.
Radiocarbon dating works by comparing the amount of normal carbon that is found in a sample with the amount of radioactive carbon.
Both carbon and radioactive carbon are found in every living organism.
It is too soon to know whether the discovery will seriously upset the estimated dates of events like the arrival of human beings in the Western Hemisphere, scientists said.
