About 20 years ago, DNA sequences were separately described from the quagga (a type of zebra) and an ancient Egyptian individual. What made these DNA sequences exceptional was that they were derived from 140- and 2400-year-old specimens. However, ancient DNA research, defined broadly as the retrieval of DNA sequences from museum specimens, archaeological finds, fossil remains, and other unusual sources of DNA, only really became feasible with the advent of techniques for the enzymatic…

Ancient DNA analysis
TLDR
This Primer outlines the best ways to find, handle and analyse ancient DNA from various sources and summarizes ethical considerations and the importance of working closely with all stakeholders, including archaeologists, curators and descendant communities.
Ancient DNA
TLDR
Ancient DNA has benefited in particular from recent advances in high-throughput sequencing technologies and from the development of analytical techniques that take advantage of the evolutionary information gained by sampling genetic data over both space and time.
V.15. Ancient DNA
TLDR
Ancient DNA has benefited in particular from recent advances in high-throughput sequencing technologies and from the development of analytical techniques that take advantage of the evolutionary information gained by sampling genetic data over both space and time.
Ancient human DNA: Phylogenetic applications
TLDR
The development of new high-throughput sequencing technologies has revolutionised the study of ancient human DNA and provided increasingly more detailed insights into the origin and development of the authors' own species.
Ancient DNA studies: new perspectives on old samples
TLDR
The methodologies applied to ancient DNA analysis are reviewed and the perspectives that next-generation sequencing applications provide in this field are reviewed.
From genes to genomes: what is new in ancient DNA?
TLDR
In this review some of the latest methodological developments in ancient DNA research will be discussed, in particular how new approaches allow us to overcome previous limitations while working with ancient hominin DNA.
Ancient plant DNA: review and prospects.
TLDR
The trend from species identification to population-level investigation is emphasized and the potential and the difficulties in this field, related to DNA preservation and to risks of contamination are highlighted.
Methodchallenges in the analysis of ancient DNA
TLDR
These analyses demonstrate the importance of closely related genomic sequence for correctly identifying and classifying bona fide endogenous DNA fragments and show that more accurate genome divergence estimates from ancient DNA sequence can be attained using at least two outgroup genomes and appropriate filtering.

The retrieval of ancient human DNA sequences.
TLDR
These results show that more experimental work than is often applied is necessary to ensure that DNA sequences amplified from ancient human remains are authentic and quantitation of the numbers of amplifiable molecules is a useful tool to determine the role of contaminating contemporary molecules and PCR errors in amplifications from ancient DNA.
Authenticating DNA Extracted From Ancient Skeletal Remains
TLDR
Work with a range of Holocene skeletal material from domestic animals and humans suggests that more than 50% of skeletal remains from the past two thousand years are likely to contain amplifiable endogenous DNA, but that in the case of human material great care is needed to distinguish this from contamination introduced before the samples reach the laboratory.
Ancient DNA analysis of human populations.
TLDR
Five well-preserved skeletal specimens from the western United States dating from 800-1600 A.D. yielded DNA samples with levels of contamination ranging from 0-100%, as determined by the presence or absence of New World-specific mitochondrial markers.
Miocene DNA sequences — a dream come true?
DNA sequences from the quagga, an extinct member of the horse family
TLDR
Dried muscle from a museum specimen of the quagga, a zebra-like species that became extinct in 1883, is examined, and DNA was extracted in amounts approaching 1% of that expected from fresh muscle, and that the DNA was of relatively low molecular weight.
Chloroplast DNA sequence from a Miocene Magnolia species
TLDR
The extraction of DNA from fossil leaf samples from the Miocene Clarkia deposit, the amplification of an 820-base pair DNA fragment from the chloroplast gene rbcL from a fossil of the genus Magnolia, and its subsequent sequencing extend the ability to analyse ancient DNA and may open new avenues into problems in palaeobotany, biogeography, and in the calibration of mutation rates.
Nuclear DNA sequences detect species limits in ancient moa
TLDR
The results show that moa were characterized by extreme reverse sexual dimorphism and as a result they have been able to clarify the number of moa species and illustrates that single-locus nuclear DNA sequences can be consistently recovered from ancient material.
An rbcL sequence from a Miocene Taxodium (bald cypress).
TLDR
The successful amplification, sequencing, and analysis of a 1320-base-pair portion of the chloroplast gene rbcL from a Miocene Taxodium specimen, also from the Clarkia site, suggest that it may be possible to isolate and sequence DNAs routinely from the Miocene Clarkia deposit.
Recovery of 16S ribosomal RNA gene fragments from ancient halite
TLDR
Terminal restriction fragment length polymorphism analyses indicate complex and different populations of microorganisms or their free DNA in ancient halites of different ages.
Molecular cloning of Ancient Egyptian mummy DNA
TLDR
Analysis of 23 mummies investigated for DNA content show that substantial pieces of mummy DNA can be cloned and that the DNA fragments seem to contain little or no modifications introduced postmortem.
