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 animal specimens. In plants, ancient DNA can be extracted from seeds and tissue. Archaeogenetics provides us with genetic evidence of ancient population group migrations,[1] domestication events, and plant and animal evolution.[2] The ancient DNA cross referenced with the DNA of relative modern genetic populations allows researchers to run comparison studies that provide a more complete analysis when ancient DNA is compromised.[3]
Archaeogenetics receives its name from the Greek word arkhaios, meaning "ancient", and the term genetics, meaning "the study of heredity".[4] The term archaeogenetics was conceived by archaeologist Colin Renfrew.[5]
In February 2021, scientists reported the oldest DNA ever sequenced was successfully retrieved from a mammoth dating back over a million years.[6][7]
