Accuracy of ancient dating methods
" Given the rapid increase in the number of ancient skeletons with published DNA, we believe that our technique will be useful to develop alternative hypotheses," Dr Esposito will say.
Chair of the ESHG conference, Professor Joris Veltman, Director of the Institute of Genetic Medicine at Newcastle University in Newcastle, United Kingdom, said: "This study shows how DNA derived from ancient skeletons can be used to more accurately determine the age of the skeleton than traditional radiocarbon tracing methods.
In this context, dating ancient skeletons is of key importance for obtaining reliable and accurate results, " says Dr Esposito.
" Through this work, together with other projects that we are working on in the lab, we will be able to achieve a better understanding of the historical developments that took place from the beginning of the Neolithic period, with the introduction of farming practices in Europe, and throughout the Bronze and Iron Ages.
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 application of radiocarbon dating to determine the geochronology of archaeological sites is ubiquitous across the African continent.Accelerator mass spectrometry has made radiocarbon dating the most precise method to determine the death of living organisms that occurred within the last 50,000 years.A new study has shed new light on the use of mollusc shells as personal adornments by Bronze Age people.The research team used amino acid racemisation analysis (a technique used previously mainly ...Legacy radiocarbon ages must be critically examined for what method was used to generate the age, and calibration radiocarbon ages from critical periods of African prehistory lack precision to resolve significant debates.A multipronged dating strategy and careful selection of radiocarbon sample materials are advocated from the earliest stages of research design. Cette revue fournit les archéologues africanistes avec des appréciations et des mises en garde sur l’utilisation des âges radiocarbone.However, the method is not without limitations and this review article provides Africanist archaeologists with cautionary insights as to when, where, and how to utilize radiocarbon dates.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.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 ...
