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,...
Only five species of the once-diverse Rhinocerotidae remain, making reconstruction their evolutionary history a challenge to biologists since Darwin. We sequenced genomes from rhinoceros (three extinct and two living), which we compared existing data remaining three living range outgroups. identify an early divergence between extant African Eurasian lineages, resolving key debate regarding phylogeny rhinoceroses. This Miocene (∼16 million years ago [mya]) split post-dates land bridge...
Ancient DNA has significantly improved our understanding of the evolution and population history extinct megafauna. However, few studies have used complete ancient genomes to examine species responses climate change prior extinction. The woolly rhinoceros (Coelodonta antiquitatis) was a cold-adapted megaherbivore widely distributed across northern Eurasia during Late Pleistocene became approximately 14 thousand years before present (ka BP). While humans been proposed as potential causes...
The Bering Land Bridge (BLB) last connected Eurasia and North America during the Late Pleistocene. Although BLB would have enabled transfers of terrestrial biota in both directions, it also acted as an ecological filter whose permeability varied considerably over time. Here we explore possible impacts this corridor on genetic diversity within, connectivity among, populations a once wide-ranging group, caballine horses (Equus spp.). Using panel 187 mitochondrial eight nuclear genomes...
The extinct cave lion (Panthera spelaea) was an apex predator of the Pleistocene, and one largest felid species ever to exist. We report first mitochondrial genome sequences for this species, derived from two Beringian specimens, which has been radiocarbon dated 29,860 ± 210 14C a BP. Phylogenetic analysis confirms placement as sister taxon populations modern (P. leo). Using newly recovered stem pantherine fossils calibrate molecular clock, we estimate that P. spelaea leo diverged about 1.89...
Climate affects habitat, food availability, and the movement sustainability of all life. In this work, we apply Indigenous Western scientific methods, including genomics isotope profiling, on fossils from across Beringia to explore effect climate change horses. We find that Late Pleistocene horses Alaska northern Yukon are related populations Eurasia crossed Bering land bridge multiple times during last glacial interval. also deeply divergent lineages north south American ice sheets...
An incomplete carcass of an extinct bison, Bison ex gr. priscus , was discovered in 2012 the mouth Rauchua River (69°30′N, 166°49′E), Chukotka. The included rump with two hind limbs, ribs, and large flap hide from abdomen sides, several vertebrae, bones forelimbs anterior autopodia, stomach its contents, wool. limb are relatively gracile, which is unusual a SEM study hair microstructure suggests higher insulating capacity than extant members genus. Additionally, mitochondrial DNA analyses...
Abstract The skull of the extinct rhinoceros Stephanorhinus kirchbergensis (Jäger, 1839) was discovered in Chondon River valley (Arctic Yakutia, Russia) during summer 2014. This is first find above Arctic Circle, expanding significantly known geographic range genus. 14 C dating and geologic evidence indicate that dates to between 48,000 70,000 yr, corresponding Marine Oxygen Isotope Stage 4/3. It thus among latest records this species. To explore evolutionary natural history relatively...
The extinct woolly rhinoceros Coelodonta antiquitatis is a prominent member of the Mammuthus-Coelodonta faunal complex, but its biology poorly known, partly because very few specimens with well-preserved soft tissues have been discovered to date. However, permafrost-preserved horns are recording structures which contain isotopic records diet, environmental conditions and physiological status animal during most life. In this study we report first data on pattern carbon (13C/12C) nitrogen...
An accumulation of mammoth hair, discovered in the Bol'shaya Chukochya River valley (northeast Yakutia, Russia), was found to contain remains terrestrial and aquatic organisms, including plants, insects, crustaceans, birds mammals. Radiocarbon dating indicated that this post‐mortem taphocoenosis represented multiple time periods. The hair dated older than 45 ka BP , plants were 12 750±50 a (which corresponds shift environmental conditions landscapes during formation thermokarst northeastern...
ABSTRACT Ancient DNA (aDNA) sequencing has enabled unprecedented reconstruction of speciation, migration, and admixture events for extinct taxa 1 . Outside the permafrost, however, irreversible aDNA post-mortem degradation 2 so far limited recovery within ˜0.5 million years (Ma) time range 3 Tandem mass spectrometry (MS)-based collagen type I (COL1) provides direct access to older biomolecular information 4 , though with phylogenetic use. In absence molecular evidence, speciation several...

The cortex has numerous longitudinal slits, which some authors misinterpret as medullae. In species, medulla is degenerative does not affect insulation properties hairs....
A pioneer comprehensive study of several diminutive last‐generation woolly mammoth teeth (M3) found on the coast East Siberian Sea between mouths Alazeya and Malaya Kuropatoch'ya rivers was conducted. Two belonged to one individual. These have a similar lamellar frequency enamel thickness as Mammuthus primigenius Blumenbach. The molar crowns from lower region are in size those small Late Pleistocene–Holocene mammoths Wrangel Island. However, number plates (17–19, excluding talons) is much...
