It compares carbon-14 levels in tissues with the atmospheric spike from 1950s nuclear testing to estimate when tissues formed.
Yes. Tooth enamel forms in childhood at known ages, so its carbon-14 level can help estimate when a person was born.
Results are ranges, can sometimes match two points on the curve and have become less precise for recent decades.
No. It narrows age and time estimates, while identity must be confirmed through DNA, dental records or other scientific methods.
Stable isotopes can suggest regions where a person lived, adding geographic clues to the age and time estimates.
