Separating endogenous ancient DNA from modern day contamination in a Siberian Neandertal
Open accessAbstract
One of the main impediments for obtaining DNA sequences from ancient human skeletons is the presence of contaminating modern human DNA molecules in many fossil samples and laboratory reagents. However, DNA fragments isolated from ancient specimens 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.

In the citing paper
“By characterizing damage patterns, users can distinguish authentic aDNA from modern contaminants, thereby ensuring the integrity of the dataset (Jónsson et al. 2013, Skoglund et al. 2014).”

In the citing paper
“Cytosine deamination can also be estimated using the tool PMDtools 55 on data generated following full USER-treatment by conditioning on CpG dinucleotides 125 , since these are heavily methylated in the nuclear genomes of vertebrates and protected from USER degradation.”

In the citing paper
“For highly degraded or contaminated material, analyses may be conditioned on reads showing evidence of post-mortem DNA damage 55,189,192 and/or limited to transversions 7 so as to mitigate both rampant contamination and damage-related nucleotide misincorporation.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
