Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material.
But new research shows that commonly accepted radiocarbon dating standards ...
In addition, it is a delicate procedure that can yield very different dates if done incorrectly.
The new technique provides results similar to those obtained by radiocarbon dating, but using a completely new DNA-based approach that can complement radiocarbon dating or be used when radiocarbon dating is unreliable.
Specifically, the review will concentrate on the potential of carbon reservoirs and recycled organic remains to inflate apparent age estimates, diagenesis of carbon isotopes in variable p H ecologies, and hot-humid climates and non-climate-controlled archives that can compromise the efficacy of samples.
This study adds a powerful instrument to the growing toolkit of paleogeneticists that can contribute to our understanding of ancient cultures, most of which are currently known from archaeology and ancient literature," says Dr Esposito.
Radiocarbon technology requires certain levels of radiocarbon on the skeleton, and this is not always available.
At this point, in its embryonic state, TPS has already shown that its results are very similar to those obtained with traditional radiocarbon dating.
We found that the average difference between our age predictions on samples that existed up to 45,000 years ago, and those given by radiocarbon dating, was 800 years.
