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 ...
The first identification of a Denisovan individual occurred in 2010, based on mitochondrial DNA (mtDNA) extracted from a juvenile female finger bone excavated from the Siberian Denisova Cave in the Altai Mountains in 2008. [2] Nuclear DNA indicates close affinities with Neanderthals. The cave was also periodically inhabited by Neanderthals, but ...
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 ...
Ancient DNA extracted from skeletons in burial sites across England shows evidence of mass migration from Europe and movement of people from as far as West Africa, challenging perceptions that ...
The simplest definition of "paleontology" is "the study of ancient life". [5] The field seeks information about several aspects of past organisms: "their identity and origin, their environment and evolution, and what they can tell us about the Earth's organic and inorganic past".
Bone fragments unearthed in a cave in central Germany show that our species ventured into Europe's cold higher latitudes more than 45,000 years ago - much earlier than previously known - in a ...
Neanderthal DNA extraction. Working in a clean room, researchers at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, took extensive precautions to avoid contaminating Neanderthal DNA samples - extracted from bones like this one - with DNA from any other source, including modern humans.
