Ancient DNA (aDNA) is DNA isolated from ancient sources (typically specimens, but also environmental DNA). [ 1 ] [ 2 ] Due to degradation processes (including cross-linking , deamination and fragmentation ) [ 3 ] ancient DNA is more degraded in comparison with contemporary genetic material. [ 4 ]
A view of Pompeii, the ancient Roman city near modern Naples in Italy, is seen in 1979. An estimated 2,000 people died in the city during the eruption of the nearby Mount Vesuvius. ((AP Photo, File))
Ancient DNA recovered from Pompeii shows that people found holding one another beneath the volcanic ash weren’t related in the ... When excavations began at the Pompeii site centuries later ...
Who We Are and How We Got Here is a 2018 book on the contribution of genome-wide ancient DNA research to human population genetics by the geneticist David Reich.He describes discoveries made by his group and others, based on analysis and comparison of ancient and modern DNA from human populations around the world.
Archaeogenetics is the study of ancient DNA using various molecular genetic methods and DNA resources. This form of genetic analysis can be applied to human, animal, and plant specimens. Ancient DNA can be extracted from various fossilized specimens including bones, eggshells, and artificially preserved tissues in human and animal specimens.
Scientists turn to ancient DNA to understand the history of Easter Island, a remote island in the Pacific Ocean also known as Rapa Nui.
Paleogenomics is a field of science based on the reconstruction and analysis of genomic information in extinct species.Improved methods for the extraction of ancient DNA (aDNA) from museum artifacts, ice cores, archeological or paleontological sites, and next-generation sequencing technologies have spurred this field.
DNA recovered from the bones of ancient Europeans is shedding light on the genetic origins of the debilitating disease multiple sclerosis. Gene that protected humans 5,000 years ago may be linked ...
