We found that the average difference between our age predictions on samples that existed up to 45, years ago, and those given by radiocarbon dating, was years. Radiocarbon technology requires certain levels of radiocarbon on the skeleton, and this is not always available. In addition, it is a delicate procedure that can yield very different dates if done incorrectly.
New technique provides accurate dating of ancient skeletons – Popular Archeology
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. The study of genetic data allows us to uncover long-lasting questions about migrations and population mixing in the past. These periods include some of the most crucial events involving the population movements and replacements that shaped our world.
The technique is also expected to be valuable for genealogy. Health research will benefit too. Since the study of genetic disorders is closely tied up with questions of ancestry and population stratification, being able to analyze the homogeneity of populations is of vital importance to epidemiologists.
This is another example of the power of modern genomics technologies to assist in helping us understand where we come from, how the journeys of our forefathers have helped shape our current genome and how this now impacts our current abilities and weaknesses, including risks of disease.

When an animal or plant dies, it stops exchanging carbon with its environment, and measuring the amount that remains provides a method of determining when it died. Cover image, above right: A Neolithic period skeleton unearthed in Israel. Become a Popular Archaeology premium subscriber.
