The geographic and temporal origins of the domestic dog remain controversial, as genetic data suggest a domestication process in East Asia beginning 15,000 years ago, whereas oldest doglike fossils are found Europe Siberia date to >30,000 ago. We analyzed mitochondrial genomes 18 prehistoric canids from Eurasia New World, along with comprehensive panel modern dogs wolves. all phylogenetically most closely related either ancient or Europe. Molecular dating suggests an onset there 18,800...
Abstract Ancient DNA research has been revolutionized following development of next-generation sequencing platforms. Although a number such platforms have applied to ancient samples, the Illumina series are dominant choice today, mainly because high production capacities and short read production. Recently potentially attractive alternative platform for palaeogenomic data generation developed, BGISEQ-500, whose sequence output comparable with series. In this study, we modified standard...
Horse domestication revolutionized warfare and accelerated travel, trade, the geographic expansion of languages. Here, we present largest DNA time series for a non-human organism to date, including genome-scale data from 149 ancient animals 129 genomes (≥1-fold coverage), 87 which are new. This extensive dataset allows us assess modern legacy past equestrian civilizations. We find that two extinct horse lineages existed during early domestication, one at far western (Iberia) other eastern...
Dogs were the first domestic animal, but little is known about their population history and to what extent it was linked humans. We sequenced 27 ancient dog genomes found that all dogs share a common ancestry distinct from present-day wolves, with limited gene flow wolves since domestication substantial dog-to-wolf flow. By 11,000 years ago, at least five major lineages had diversified, demonstrating deep genetic of during Paleolithic. Coanalysis human reveals aspects mirror humans,...
Abstract Domestication of horses fundamentally transformed long-range mobility and warfare 1 . However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence bridling, milking corralling 2–4 at Botai, Central Asia around 3500 bc 3 Other longstanding candidate regions for domestication, such as Iberia 5 Anatolia 6 , have also recently been challenged. Thus, genetic, geographic temporal origins remained unknown. Here we...
Abstract The grey wolf ( Canis lupus ) was the first species to give rise a domestic population, and they remained widespread throughout last Ice Age when many other large mammal went extinct. Little is known, however, about history possible extinction of past populations or where progenitors present-day dog lineage familiaris lived 1–8 . Here we analysed 72 ancient genomes spanning 100,000 years from Europe, Siberia North America. We found that were highly connected Late Pleistocene, with...
Although the application of sequencing-by-synthesis techniques to DNA extracted from bones has revolutionized study ancient DNA, it been plagued by large fractions contaminating environmental DNA. The genetic analyses hair shafts could be a solution: We present 10 previously unexamined Siberian mammoth (Mammuthus primigenius) mitochondrial genomes, sequenced with up 48-fold coverage. observed levels damage-derived sequencing errors were lower than those in published frozen bone samples, even...
We report five new complete mitochondrial DNA (mtDNA) genomes of Siberian woolly mammoth ( Mammuthus primigenius ), sequenced with up to 73-fold coverage from extracted hair shaft material. Three the sequences present first mtDNA clade II. Analysis these and 13 recently published demonstrates existence two apparently sympatric clades that exhibit high interclade divergence. The analytical power afforded by analysis reveals a surprisingly ancient coalescence age clades, ≈1–2 million years,...
How species respond to an increased availability of habitat, for example at the end last glaciation, has been well established. In contrast, little is known about opposite process, when amount habitat decreases. The hypothesis tracking predicts that should be able track both increases and decreases in availability. alternative populations outside refugia become extinct during periods unsuitable climate. To test these hypotheses, we used ancient DNA techniques examine genetic variation arctic...
In Eurasia, the period between 40,000 and 30,000 BP saw replacement of Neandertals by anatomically modern humans (AMH) during after Middle to Upper Paleolithic transition. The human fossil record for this is very poorly defined with no overlap AMH on basis direct dates. Four new (14)C dates were obtained two adult from Spy (Belgium). results show that survived at least approximately 36,000 in Belgium fossils may be associated Lincombian-Ranisian-Jerzmanowician, a transitional techno-complex...
Abstract Almost 150 years after the first identification of Neandertal skeletal material, cognitive and symbolic abilities these populations remain a subject intense debate. We present 99 new remains from Troisième caverne Goyet (Belgium) dated to 40,500–45,500 calBP. The were identified through multidisciplinary study that combines morphometrics, taphonomy, stable isotopes, radiocarbon dating genetic analyses. bones show distinctive anthropogenic modifications, which provides clear evidence...
Abstract Grey wolves ( Canis lupus ) are one of the few large terrestrial carnivores that have maintained a wide geographical distribution across Northern Hemisphere throughout Pleistocene and Holocene. Recent genetic studies suggested that, despite this continuous presence, major demographic changes occurred in wolf populations between Late early Holocene, extant trace their ancestry to single population. Both origin ancestral population how it became widespread remain unknown. Here, we...

The Late Pleistocene global extinction of many terrestrial mammal species has been a subject intensive scientific study for over century, yet the relative contributions environmental changes and expansion humans remain unresolved. A defining component these extinctions is bias toward large species, with majority small-mammal taxa apparently surviving into present. Here, we investigate population-level history key tundra-specialist small mammal, collared lemming ( Dicrostonyx torquatus ), to...
Ancient DNA analyses have provided enhanced resolution of population histories in many Pleistocene taxa. However, most studies are spatially restricted, making inference species-level biogeographic difficult. Here, we analyse mitochondrial (mtDNA) variation the woolly mammoth from across its Holarctic range to reconstruct history over last 200 thousand years (kyr). We identify a previously undocumented major mtDNA lineage Europe, which was replaced by another 32-34 kyr before present (BP)....
Abstract Correlating cultural, technological and ecological aspects of both Upper Pleistocene modern humans (UPMHs) Neandertals provides a useful approach for achieving robust predictions about what makes us human. Here we present information period special relevance in human evolution, the time replacement by during Late Europe. Using stable isotopic approach, shed light on diet mobility late UPMHs from cave sites Troisième caverne Goyet Spy Belgium. We demonstrate that their was...
