In this context, dating ancient skeletons is of key importance for obtaining reliable and accurate results, " says Dr. "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 technique is also expected to be valuable for genealogy. Since the study of genetic disorders is closely tied up with questions of ancestry and population stratification, being able to analyse the homogeneity of populations is of vital importance to epidemiologists.
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. Radiocarbon technology requires certain levels of radiocarbon on the skeleton, and this is not always available.
"This permits us to open a powerful window on our past.
"When applying our ancient DNA dating technology to modern genomes, we have seen that some populations have more ancient genomes than others, and this can be helpful in establishing individual origins," says Dr. The researchers are currently compiling a larger dataset to increase the geographical/time coverage of their model and improve its accuracy.
"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. 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.
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 ...
" 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.However, radiocarbon techniques commonly used to date and analyse DNA from ancient skeletons can be inaccurate and difficult to apply.Inspired by the Geographic Population Structure model that can track mutations associated with geography, researchers have developed a new analytic method, the Time Population Structure (TPS), that uses mutations to predict time in order to date the ancient DNA. Umberto Esposito, a postdoctoral research in the laboratory of Dr.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.
