“…However, this does not imply a direct line of descent from the first domesticated population, which may be extinct [18,36] or swamped by admixture. We acknowledge that a major expansion from East Asia may not be the only scenario consistent with our data, however this conclusion is also supported by other independent datasets of modern Asian FBDs based on different types of genetic markers [10,12,15,17,39]. These earlier studies differ in the precise location of the source population (Southeast versus Central Asia) and in the interpretation of this expansion as a primary [10,12,15,39] or secondary [17] wave.…”

Although a large part of the global domestic dog population is free-ranging and free-breeding, knowledge of genetic diversity in these free-breeding dogs (FBDs) and their ancestry relations to pure-breed dogs is limited, and the indigenous status of FBDs in Asia is still uncertain. We analyse genome-wide SNP variability of FBDs across Eurasia, and show that they display weak genetic structure and are genetically distinct from pure-breed dogs rather than constituting an admixture of breeds. Our results suggest that modern European breeds originated locally from European FBDs. East Asian and Arctic breeds show closest affinity to East Asian FBDs, and they both represent the earliest branching lineages in the phylogeny of extant Eurasian dogs. Our biogeographic reconstruction of ancestral distributions indicates a gradual westward expansion of East Asian indigenous dogs to the Middle East and Europe through Central and West Asia, providing evidence for a major expansion that shaped the patterns of genetic differentiation in modern dogs. This expansion was probably secondary and could have led to the replacement of earlier resident populations in Western Eurasia. This could explain why earlier studies based on modern DNA suggest East Asia as the region of dog origin, while ancient DNA and archaeological data point to Western Eurasia.

“…The tree was subsequently deposited in DomeTree (Build 1) (http://www.dometree.org/) as an open resource in 2015 [8]. That same year, Fregel et al [9] and Duleba et al [10] also reported two mtDNA haplogroup trees for dog. However, these three different dog mtDNA haplogroup trees show conflicting scoring of variants and haplogroup nomenclatures, a potential recipe for confusion in future related studies.…”

“…Sequences from ancient Iberian Canis remains are depicted in bold. Extant dog data from GenBank include the following: 54 sequences trimmed from mitogenome data (Duleba et al, 2015), haplogroup/sub-haplogroup nomenclature precedes accession number information; 49 sequences from modern Iberian native breeds and Iberian village dogs (Pires et al, 2006), with haplogroup letters, accession numbers and haplotype numbers shown; 4 Portuguese, 10 Spanish and 14 North African dogs (Pang et al, 2009), with haplogroup letters and haplotype numbers also indicated. Major haplogroups are coloured as follows: A-orange; B-yellow; C-blue; and D-green.…”

“…Median-joining network of mtDNA sequences. Clades A, B, C and D represent the major haplogroups found in extant dogs as defined by mitogenomes in Duleba et al (2015). Five distinct ancient haplotypes were recovered from Roman dog samples (black) and which clustered with haplotypes A and D of extant dogs (gray).…”

a b s t r a c tIn this study, we integrate osteometric and palaeogenetic data to investigate dog variability in the Roman Empire in Iberia and North Africa. Osteometry was used to distinguish the statusddomestic or wild, of approximately 2000 years old Canis remains and to understand to what extent teeth and long bones varied in dogs in the Roman provinces of Mauretania Tingitana, Lusitania and Tarraconensis. Highthroughput 454-DNA sequencing technology was used to obtain mitochondrial DNA (mtDNA) sequences from 15 bone and teeth samples. We identified five dog haplotypes from partial sequences of the hypervariable D-loop region. MtDNA haplotypes were grouped into two of the four major clades found in present-day dogs. We detected three clade A haplotypes in 12 samples from Portugal, Spain and Morocco, and a single clade D haplotype in 3 samples from Spain. So far, this is the oldest evidence for the presence of dog clade D in Iberia. It is dated to the late Roman occupation in the 4th-5th cent. AD (ca. 1,600 years ago).Our results confirm the existence of distinct dog morphotypes in Roman times that also harboured distinct genetic lineages. According to our data, dogs from distinct mtDNA lineages (clades A and D) have been continuously bred in the Iberian Peninsula since at least 1600 years ago. Moreover, the sharing of matrilines between dogs from Spain and North Africa may indicate gene flow. Dogs could have been easily transported between these regions by humans along maritime and terrestrial trade routes. These results provide new insights into pre-Roman and Roman domestication practices, confirming selection practices were extensively applied to dogs during the first centuries of our era in the Iberian Peninsula. We show that the greater size variability of teeth length (and consequently cranium) and long bone breadths (and consequently phenotype) of Roman dogs in the Iberian Peninsula, is concomitant with the detection of diverse and rare maternal lineages. This would reflect an intensification of dog breeding and the use of non-local dogs for breeding.
