A theoretical analysis of taxonomic binning accuracy
The results quantify the degradation in assignment accuracy as the samples diverge from their closest reference sequence, and with incompleteness of reference sequences.
Microstratigraphic preservation of ancient faunal and hominin DNA in Pleistocene cave sediments
It is shown that impregnated blocks of intact sediment are excellent archives of DNA and can preserve DNA of hominins and other mammals and provides a means of linking genetic information to the archaeological and ecological records on a microstratigraphic scale.
Evaluating Claims of Early Human Occupation at Chiquihuite Cave, Mexico
ABSTRACT Archaeologists working in Mexico recently claimed evidence for pre-Last Glacial Maximum human occupation in the Americas, based on lithic items excavated from Chiquihuite Cave, Zacatecas.
Soot and charcoal are reservoirs of extracellular DNA
It is demonstrated how the interaction between DNA and soot and charcoal partly occurs via terminal basepairs, suggesting that, besides electrostatic forces, hydrophobic interactions play an important role in binding.
Integrating multi-taxon palaeogenomes and sedimentary ancient DNA to study past ecosystem dynamics
It is timely to develop an integrative approach to aDNA studies by combining data from multiple taxa and substrates to provide a more comprehensive understanding of ecosystem-wide changes.
Placing Ancient DNA Sequences into Reference Phylogenies
This work provides an automated workflow for jointly analysing ancient and present-day sequence data in a phylogenetic context and provides both a parsimony approach and a highly optimised likelihood-based approach that assigns a posterior probability to each branch.


Polar and brown bear genomes reveal ancient admixture and demographic footprints of past climate change
It is demonstrated that brown bears and PBs have had sufficiently independent evolutionary histories over the last 4–5 million years to leave imprints in the PB nuclear genome that likely are associated with ecological adaptation to the Arctic environment.
Ancient and modern environmental DNA
EDNA has revealed an ancient forest in Greenland, extended by several thousand years the survival dates for mainland woolly mammoth in Alaska, and pushed back the dates for spruce survival in Scandinavian ice-free refugia during the last glaciation.
Mitochondrial genomes reveal an explosive radiation of extinct and extant bears near the Miocene-Pliocene boundary
Molecular dating of the mtDNA divergence times suggests a rapid radiation of bears in both the Old and New Worlds around 5 million years ago, at the Miocene-Pliocene boundary, which coincides with major global changes, such as the Messinian crisis and the first opening of the Bering Strait, and suggests a global influence of such events on species radiations.
Complete mitochondrial genome sequence of a Middle Pleistocene cave bear reconstructed from ultrashort DNA fragments
The results prove that authentic ancient DNA can be preserved for hundreds of thousand years outside of permafrost and enable the retrieval of phylogenetically informative sequences from samples in which virtually all DNA is diminished to fragments shorter than 50 bp.
The evolutionary history of bears is characterized by gene flow across species
A genome analysis of the bear family with representatives of all living species shows that gene flow is not limited to closely related species pairs and necessitates shifting the attention from speciation processes achieving genome-wide reproductive isolation to the selective processes that maintain species divergence in the face of gene flow.
Hybridization capture of larch (Larix Mill) chloroplast genomes from sedimentary ancient DNA reveals past changes of Siberian forests
This study demonstrates for the first time that hybridization capture applied to ancient DNA from lake sediments can provide genome-scale information and is a viable tool for studying past changes of a specific taxon.
A Paleogenomic Perspective on Evolution and Gene Function: New Insights from Ancient DNA
The origins and growth of this field are reviewed and how challenges owing to the limited amount of DNA available for analysis and the possibility of contamination by modern material have been overcome are explained.
DNA evidence of bowhead whale exploitation by Greenlandic Paleo-Inuit 4,000 years ago
A comprehensive record of past subsistence economies in Greenland is reconstructed by sequencing ancient DNA from four well-described midden deposits, confirming that the species found in the fossil record were a vital part of Inuit subsistence and adding a new dimension with evidence that caribou, walrus and whale species played a more prominent role for the survival of Paleo-Inuit cultures than previously reported.
A fossil bear from northeastern Brazil, with a phylogenetic analysis of the South American extinct Tremarctinae (Ursidae)
The skull with mandible of a fossil tremarctine bear from Ubajara county, northeastern Brazil, is described and compared to other specimens belonging to the nominal species, Arctodus (Pararctotherium) brasiliensis, and a phylogenetic hypothesis and correspondent classification for the genera of Tremarctinae are proposed, using cladistic methodology.
