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))
Scientists turn to ancient DNA to understand the history of Easter Island, a remote island in the Pacific Ocean also known as Rapa Nui. New evidence upends contentious Easter Island theory ...
Pontus Skoglund (born 3 March 1984) is a Swedish population geneticist, currently at the Francis Crick Institute and formerly at Harvard Medical School.. Skoglund studies ancient DNA to verify human history, mostly about how humans populated Earth.
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.
Ancient DNA recovered from Pompeii shows that people found holding one another beneath the volcanic ash weren’t related in the ways we think. DNA analysis upends long-held assumptions about ...
The team compared the ancient DNA with that of 68 residents of the present-day Maya community of Tixcacaltuyub. The researchers found the two shared a close genetic signature.
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.
