Ancient DNA (aDNA) is DNA isolated from ancient sources ... This DNA had a half-life significantly longer than previous research, of up to 15,000 years. Kirkpatrick's ...
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.
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
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 ...
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.

This week, an analysis of ancient DNA sheds light on a bygone empire, Voyager 1 is back in touch with NASA, what to do now that the cicadas are here, and more.
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 ...
Denisova 4, a molar. The Denisovans or Denisova hominins (/ d ə ˈ n iː s ə v ə / də-NEE-sə-və) are an extinct species or subspecies of archaic human that ranged across Asia during the Lower and Middle Paleolithic, and lived, based on current evidence, from 285 thousand to 25 thousand years ago. [1]
