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 ]
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.
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))
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.
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 ...
The findings, published in a series of articles in Current Archaeology, come from one of the largest ancient DNA projects in Europe involving 460 people who were buried in graves between 200AD and ...
Museomics is the study of genomic data obtained from ancient DNA (aDNA) and historic DNA (hDNA) specimens in museum collections. [1] [2] Early research in this area focused on short sequences of DNA from mitochondrial genes, but sequencing of whole genomes has become possible. [1]
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 ...
