Ancient DNA. Cross-linked DNA extracted from the 4,000-year-old liver of the ancient Egyptian priest Nekht-Ankh. 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 ...
Archaeogenetics. 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 ...
History. The study of molecular paleontology is said to have begun with the discovery by Abelson of 360 million year old amino acids preserved in fossil shells. [12] However, Svante Pääbo is often the one considered to be the founder of the field of molecular paleontology. [13]
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 ...
DNA analysis indicates the older male was the adolescents’ father. The researchers believe that given the man’s age, it is likely he was present at their burial.
Paleogenomics. 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.
Paleogenetics is the study of the past through the examination of preserved genetic material from the remains of ancient organisms. [1][2] Emile Zuckerkandl and Linus Pauling introduced the term in 1963, long before the sequencing of DNA, in reference to the possible reconstruction of the corresponding polypeptide sequences of past organisms.

Institutions. University of Oslo. University of Otago. John Radcliffe Hospital. Erika Hagelberg is a British Evolutionary geneticist and Professor of Biosciences at the University of Oslo. She works on ancient DNA and pioneered a means to extract DNA from bones. Her research has applications in evolutionary biology and forensic science.
