              the possibility to sequence genomes from Pleistocene organisms.
              Here we analyze DNA sequences determined from a Neandertal, a
              mammoth, and a cave bear. We show that purines are overrepresented
              at positions adjacent to the breaks in the ancient DNA, suggesting
              that depurination has contributed to its degradation. We
              furthermore show that substitutions resulting from miscoding
              cytosine residues are vastly overrepresented in the DNA sequences
              and drastically clustered in the ends of the molecules, whereas
              other substitutions are rare. We present a model where the
              observed substitution patterns are used to estimate the rate of
              deamination of cytosine residues in single- and double-stranded
              portions of the DNA, the length of single-stranded ends, and the
              frequency of nicks. The results suggest that reliable genome
              sequences can be obtained from Pleistocene organisms.},

  abstract = {Motivation: Ancient DNA (aDNA) molecules in fossilized bones and
              teeth, coprolites, sediments, mummified specimens and museum
              collections represent fantastic sources of information for
              evolutionary biologists, revealing the agents of past epidemics
              and the dynamics of past populations. However, the analysis of
              aDNA generally faces two major issues. Firstly, sequences consist
              of a mixture of endogenous and various exogenous backgrounds,
              mostly microbial. Secondly, high nucleotide misincorporation rates
              can be observed as a result of severe post-mortem DNA damage. Such
              misincorporation patterns are instrumental to authenticate ancient
              sequences versus modern contaminants. We recently developed the
              user-friendly mapDamage package that identifies such patterns from
              next-generation sequencing (NGS) sequence datasets. The absence of
              formal statistical modeling of the DNA damage process, however,
              precluded rigorous quantitative comparisons across
              samples.Results: Here, we describe mapDamage 2.0 that extends the
              original features of mapDamage by incorporating a statistical
              model of DNA damage. Assuming that damage events depend only on
              sequencing position and post-mortem deamination, our Bayesian
              statistical framework provides estimates of four key features of
              aDNA molecules: the average length of overhangs (λ), nick
              frequency (ν) and cytosine deamination rates in both
              double-stranded regions () and overhangs (). Our model enables
              rescaling base quality scores according to their probability of
              being damaged. mapDamage 2.0 handles NGS datasets with ease and is
              compatible with a wide range of DNA library
              protocols.Availability: mapDamage 2.0 is available at

              determining the impacts of past human activities on marine

              fauna are often difficult to identify, in particular if species
              have a wide spatial distribution and lack clear osteological or
              isotopic differentiation between populations. Here, we report that
              ancient fish-bone remains, despite being porous, brittle, and
              light, provide an excellent source of endogenous DNA (15-46\%) of
              sufficient quality for whole-genome reconstruction. By comparing
              ancient sequence data to that of modern specimens, we determine
              the biological origin of 15 Viking Age (800-1066 CE) and
              subsequent medieval (1066-1280 CE) Atlantic cod (Gadus morhua)
              specimens from excavation sites in Germany, Norway, and the United

              was a fishing settlement for the procurement of local catches,
              whereas the other localities were centers of trade. Fish from the
              trade sites show a mixed ancestry and are statistically
              differentiated from local fish populations. Moreover, Viking Age
              samples from Haithabu, Germany, are traced back to the North East
              Arctic Atlantic cod population that has supported the Lofoten
              fisheries of Norway for centuries. Our results resolve a
              long-standing controversial hypothesis and indicate that the

              make up invaluable resources to study past assemblages,
              populations, and even the evolution of species. However, DNA is
              subject to degradation, and hence over time decrease to ultra low
              concentrations which makes it highly prone to contamination by
              modern sources. Strict precautions are therefore necessary to
              ensure that DNA from modern sources does not appear in the final
              data is authenticated as ancient. The most generally accepted and
              widely applied authenticity for ancient DNA studies is to test for
              elevated deaminated cytosine residues towards the termini of the
              molecules: DNA damage. To date, this has primarily been used for
              single organisms and recently for read assemblies, however, these
              methods are not applicable for estimating DNA damage for ancient
              metagenomes with tens and even hundreds of thousands of
              species.MethodsWe presentmetaDMG, a novel framework and toolkit
              that allows for the estimation, quantification and visualization
              of postmortem damage for single reads, single genomes and even
              metagenomic environmental DNA by utilizing the taxonomic branching
              structure. It bypasses any need for initial classification,
              splitting reads by individual organisms, and realignment. We have
              implemented a Bayesian approach that combines a modified geometric
              damage profile with a beta-binomial model to fit the entire model
              to the individual misincorporations at all taxonomic
              levels.ResultsWe evaluated the performance using both simulated
              and published environmental DNA datasets and compared to existing
              methods when relevant. We findmetaDMGto be an order of magnitude
              faster than previous methods and more accurate – even for complex
              metagenomes. Our simulations show thatmetaDMGcan estimate DNA
              damage at taxonomic levels down to 100 reads, that the estimated
              uncertainties decrease with increased number of reads and that the

               derived from archaeological remains, such as paleofeces and
               dental calculus, we can investigate past microbiome functional
               diversity that may be absent or underrepresented in the modern
               microbiome gene catalogue. However, compared to modern samples,
               ancient samples are often burdened with environmental
               contamination, resulting in metagenomic datasets that represent
               mixtures of ancient and modern DNA. The ability to rapidly and
               reliably establish the authenticity and integrity of ancient
               samples is essential for ancient DNA studies, and the ability to
               distinguish between ancient and modern sequences is particularly
               important for ancient microbiome studies. Characteristic patterns
               of ancient DNA damage, namely DNA fragmentation and cytosine
               deamination (observed as C-to-T transitions) are typically used
               to authenticate ancient samples and sequences, but existing tools
               for inspecting and filtering aDNA damage either compute it at the
               read level, which leads to high data loss and lower quality when
               used in combination with de novo assembly, or require manual
               inspection, which is impractical for ancient assemblies that
               typically contain tens to hundreds of thousands of contigs. To
               address these challenges, we designed PyDamage, a robust,
               automated approach for aDNA damage estimation and authentication
               of de novo assembled aDNA. PyDamage uses a likelihood ratio based
               approach to discriminate between truly ancient contigs and
               contigs originating from modern contamination. We test PyDamage
               on both on simulated aDNA data and archaeological paleofeces, and
               we demonstrate its ability to reliably and automatically identify
               contigs bearing DNA damage characteristic of aDNA. Coupled with
               aDNA de novo assembly, Pydamage opens up new doors to explore
               functional diversity in ancient metagenomic datasets.},

              show a characteristic DNA damage pattern caused by miscoding
              lesions that differs from present day DNA sequences. Here, we
              develop a framework for evaluating the likelihood of a sequence
              originating from a model with postmortem degradation-summarized in
              a postmortem degradation score-which allows the identification of
              DNA fragments that are unlikely to originate from present day
              sources. We apply this approach to a contaminated Neandertal
              specimen from Okladnikov Cave in Siberia to isolate its endogenous
              DNA from modern human contaminants and show that the reconstructed
              mitochondrial genome sequence is more closely related to the
              variation of Western Neandertals than what was discernible from
              previous analyses. Our method opens up the potential for genomic
              analysis of contaminated fossil material.},

              sequencing technologies often allows multiple samples to be
              sequenced in parallel on a single sequencing run. This is
              particularly true if subsets of the genome are studied rather than
              complete genomes. In recent years, target capture from sequencing
              libraries has largely replaced polymerase chain reaction (PCR) as
              the preferred method of target enrichment. Parallelizing target
              capture and sequencing for multiple samples requires the
              incorporation of sample-specific barcodes into sequencing
              libraries, which is necessary to trace back the sample source of
              each sequence. This protocol describes a fast and reliable method
              for the preparation of barcoded (``indexed'') sequencing libraries
              for Illumina's Genome Analyzer platform. The protocol avoids
              expensive commercial library preparation kits and can be performed
              in a 96-well plate setup using multi-channel pipettes, requiring
              not more than two or three days of lab work. Libraries can be

              DNA usually involves ligation of adapters to double-stranded DNA
              fragments. However, for highly degraded DNA, especially ancient
              DNA, library preparation has been found to be more efficient if
              each of the two DNA strands are converted into library molecules
              separately. We present a new method for single-stranded library
              preparation, ssDNA2.0, which is based on single-stranded DNA
              ligation with T4 DNA ligase utilizing a splinter oligonucleotide
              with a stretch of random bases hybridized to a 3΄ biotinylated
              donor oligonucleotide. A thorough evaluation of this ligation
              scheme shows that single-stranded DNA can be ligated to adapter
              oligonucleotides in higher concentration than with CircLigase (an
              RNA ligase that was previously chosen for end-to-end ligation in
              single-stranded library preparation) and that biases in ligation
              can be minimized when choosing splinters with 7 or 8 random
              nucleotides. We show that ssDNA2.0 tolerates higher quantities of
              input DNA than CircLigase-based library preparation, is less
              costly and better compatible with automation. We also provide an
              in-depth comparison of library preparation methods on degraded DNA

              single-stranded library preparation increases library yields from

              magnitude.},

              associated with wild rodents and their fleas. Historically it was
              responsible for three pandemics: the Plague of Justinian in the
              6th century AD, which persisted until the 8th century [1]; the
              renowned Black Death of the 14th century [2, 3], with recurrent
              outbreaks until the 18th century [4]; and the most recent 19th
              century pandemic, in which Y. pestis spread worldwide [5] and
              became endemic in several regions [6]. The discovery of molecular
              signatures of Y. pestis in prehistoric Eurasian individuals and
              two genomes from Southern Siberia suggest that Y. pestis caused
              some form of disease in humans prior to the first historically
              documented pandemic [7]. Here, we present six new European Y.
              pestis genomes spanning the Late Neolithic to the Bronze Age
              (LNBA; 4,800 to 3,700 calibrated years before present). This time

              social changes that led to cross-European networks of contact and
              exchange [8, 9]. We show that all known LNBA strains form a single
              putatively extinct clade in the Y. pestis phylogeny. Interpreting
              our data within the context of recent ancient human genomic
              evidence that suggests an increase in human mobility during the
              LNBA, we propose a possible scenario for the early spread of Y.

               assigned morphologically and genetically to Equus ovodovi, a
               species representative of Sussemionus. We present the first
               high-quality complete genome of the Sussemionus lineage, which
               was sequenced to 13.4× depth of coverage. Radiocarbon dating
               demonstrates that this lineage survived until ~3500 years ago,
               despite continued demographic collapse during the Last Glacial
               Maximum and the great human expansion in East Asia. We also
               confirmed the Equus phylogenetic tree and found that Sussemionus
               diverged from the ancestor of non-caballine equids ~2.3-2.7
               million years ago and possibly remained affected by secondary
               gene flow post-divergence. We found that the small genetic
               diversity, rather than enhanced inbreeding, limited the species'
               chances of survival. Our work adds to the growing literature
               illustrating how ancient DNA can inform on extinction dynamics
               and the long-term resilience of species surviving in cryptic
               population pockets.},

  abstract = {Dental calculus, the calcified form of the mammalian oral
              microbial plaque biofilm, is a rich source of oral microbiome,
              host, and dietary biomolecules and is well preserved in museum and
              archaeological specimens. Despite its wide presence in mammals, to
              date, dental calculus has primarily been used to study primate
              microbiome evolution. We establish dental calculus as a valuable
              tool for the study of nonhuman host microbiome evolution, by using
              shotgun metagenomics to characterize the taxonomic and functional
              composition of the oral microbiome in species as diverse as
              gorillas, bears, and reindeer. We detect oral pathogens in
              individuals with evidence of oral disease, assemble near-complete
              bacterial genomes from historical specimens, characterize
              antibiotic resistance genes, reconstruct components of the host
              diet, and recover host genetic profiles. Our work demonstrates
              that metagenomic analyses of dental calculus can be performed on a
              diverse range of mammalian species, which will allow the study of
              oral microbiome and pathogen evolution from a comparative
              perspective. As dental calculus is readily preserved through time,
              it can also facilitate the quantification of the impact of
              anthropogenic changes on wildlife and the environment.},

  abstract = {The challenge of sequencing ancient DNA has led to the development
              of specialized laboratory protocols that have focused on reducing
              contamination and maximizing the number of molecules that are
              extracted from ancient remains. Despite the fact that success in
              ancient DNA studies is typically obtained by screening many
              samples to identify a promising subset, ancient DNA protocols have
              not, in general, focused on reducing the time required to screen
              samples. We present an adaptation of a popular ancient library
              preparation method that makes screening more efficient. First, the
              DNA extract is treated using a protocol that causes characteristic
              ancient DNA damage to be restricted to the terminal nucleotides,
              while nearly eliminating it in the interior of the DNA molecules,
              allowing a single library to be used both to test for ancient DNA
              authenticity and to carry out population genetic analysis. Second,
              the DNA molecules are ligated to a unique pair of barcodes, which
              eliminates undetected cross-contamination from this step onwards.
              Third, the barcoded library molecules include incomplete adapters
              of short length that can increase the specificity of
              hybridization-based genomic target enrichment. The adapters are
              completed just before sequencing, so the same DNA library can be
              used in multiple experiments, and the sequences distinguished. We
              demonstrate this protocol on 60 ancient human samples.},
