“…7e, f) indicate that a simple, two-bottleneck model provides a close fit to the data for the breeds. They do not rule out a more complex population history, such as multiple domestication events, low levels of continuing gene flow between domestic dog and grey wolf 97,98 or multiple bottlenecks within breeds. Notably, the akita yields the poorest fit to the model, with an r 2 curve that appears to be triphasic.…”

Here we report a high-quality draft genome sequence of the domestic dog (Canis familiaris), together with a dense map of single nucleotide polymorphisms (SNPs) across breeds. The dog is of particular interest because it provides important evolutionary information and because existing breeds show great phenotypic diversity for morphological, physiological and behavioural traits. We use sequence comparison with the primate and rodent lineages to shed light on the structure and evolution of genomes and genes. Notably, the majority of the most highly conserved non-coding sequences in mammalian genomes are clustered near a small subset of genes with important roles in development. Analysis of SNPs reveals long-range haplotypes across the entire dog genome, and defines the nature of genetic diversity within and across breeds. The current SNP map now makes it possible for genome-wide association studies to identify genes responsible for diseases and traits, with important consequences for human and companion animal health.

“…a, Modern haplotype structure arose from key events in dog breeding history. The domestic dog diverged from wolves 15,000-100,000 years ago 97,119 , probably through multiple domestication events 98 . Recent dog breeds have been created within the past few hundred years.…”

“…Ancient DNA analysis of selected Late Glacial dog remains could be used to establish the relationship between prehistoric and present dog breeds. If extinct breeds can be found, these could be used to track the expansion of human groups in Europe and to investigate the interactions between indigenous populations and later immigrants [187,188]. Likewise, the genetic analysis of Late Glacial reindeer from different periods could aid in exploring their relation to each other, and to extant wild and domestic herds.…”

Adaptation and niche construction in human prehistory: a case study from the southern Scandinavian Late Glacial

The niche construction model postulates that human bio-social evolution is composed of three inheritance domains, genetic, cultural and ecological, linked by feedback selection. This paper argues that many kinds of archaeological data can serve as proxies for human niche construction processes, and presents a method for investigating specific niche construction hypotheses. To illustrate this method, the repeated emergence of specialized reindeer (Rangifer tarandus) hunting/herding economies during the Late Palaeolithic (ca 14.7-11.5 kyr BP) in southern Scandinavia is analysed from a niche construction/triple-inheritance perspective. This economic relationship resulted in the eventual domestication of Rangifer. The hypothesis of whether domestication was achieved as early as the Late Palaeolithic, and whether this required the use of domesticated dogs (Canis familiaris) as hunting, herding or transport aids, is tested via a comparative analysis using material culture-based phylogenies and ecological datasets in relation to demographic/genetic proxies. Only weak evidence for sustained niche construction behaviours by prehistoric hunter-gatherer in southern Scandinavia is found, but this study nonetheless provides interesting insights into the likely processes of dog and reindeer domestication, and into processes of adaptation in Late Glacial foragers.

“…thèse selon laquelle les chiens anciens et actuels partageraient une origine commune, celle des loups gris de l'Ancien Monde [2,3]. En revanche, la datation des événe-ments de domestication du chien ne confirme pas d'autres résultats publiés précédemment [4], mais propose de la faire remonter vers 12000-15000 ans avant J.-C.…”

“…Par ailleurs, les travaux de J.A. Leonard et al [2] et de P. Savolainen et al [3] montrent que tous les chiens domestiques actuels proviendraient de l'Est asiatique, d'où ils se seraient répandus en Europe, en Asie et vers le Nouveau Monde en accompagnant l'homme dans sa traversée du détroit de Béring, au pléistocène. La construction d'un arbre phylogénique et la répartition géographique des échantillons d'ADN analysés ont amené ces auteurs à proposer que la population des chiens actuels proviendrait d'un nombre restreint de loups femelles, et donc d'un pool limité d'allèles (et non de gènes, comme on le dit trop souvent), en dépit de ce que l'extrême variation morphologique observée actuellement laisserait supposer [3].…”
