Genomic and archaeological evidence suggest a dual origin of domestic dogs
TLDR
Results suggest that dogs may have been domesticated independently in Eastern and Western Eurasia from distinct wolf populations, and East Eurasian dogs were then possibly transported to Europe with people, where they partially replaced European Paleolithic dogs. Expand
The Evolution of Suidae.
TLDR
The current knowledge of this fascinating group of Cetartiodactyla is reviewed and a comprehensive evolutionary history from the Oligocene to the present day is provided. Expand
Microbial differences between dental plaque and historic dental calculus are related to oral biofilm maturation stage
TLDR
Overall, this work finds that there are systematic microbial differences between plaque and calculus related to biofilm physiology, and recognizing these differences is important for accurate data interpretation in studies comparing dentalplate and calculus. Expand
Ancient DNA suggests modern wolves trace their origin to a Late Pleistocene expansion from Beringia
TLDR
The results suggest that contemporary wolf populations trace their ancestry to an expansion from Beringia at the end of the Last Glacial Maximum, and that this process was most likely driven by Late Pleistocene ecological fluctuations that occurred across the Northern Hemisphere. Expand
A mitochondrial genetic divergence proxy predicts the reproductive compatibility of mammalian hybrids
TLDR
The strong correlation between genetic distance and hybrid fertility demonstrated here suggests that this proxy can be employed to predict whether the hybrid offspring of two mammalian species will follow Haldane's Rule. Expand
Speciation and domestication in Suiformes: a genomic perspective
TLDR
It is shown that, contrary to the expectation of simple models of speciation, the evolutionary history of these species involved alternating periods of gene-flow and genetic differentiation that are tightly linked to past climatic fluctuations that took place over the last 4 million years. Expand
Reconstructing Asian faunal introductions to eastern Africa from multi-proxy biomolecular and archaeological datasets
TLDR
Faunal remains from 22 eastern African sites are analysed and biomolecular techniques applied to confirm identifications of two Asian taxa: domestic chicken and black rat, supporting a late, mid-first millennium CE introduction of these species. Expand
Origins and genetic legacy of prehistoric dogs
TLDR
It is found that all dogs share a common ancestry distinct from present-day wolves, with limited gene flow from wolves since domestication but substantial dog-to-wolf gene flow. Expand
A novel MC1R allele for black coat colour reveals the Polynesian ancestry and hybridization patterns of Hawaiian feral pigs
TLDR
It is demonstrated that Hawaiian feral pigs are mostly the descendants of those originally introduced during Polynesian settlement, though there is evidence for some admixture. Expand
Specialized sledge dogs accompanied Inuit dispersal across the North American Arctic
TLDR
It is revealed that Inuit dogs derive from a secondary pre-contact migration of dogs distinct from Palaeo-Inuit dogs, and probably aided the Inuit expansion across the North American Arctic beginning around 1000 BP. Expand
