Multiple and ancient origins of the domestic dog.
Sequences from both dogs and wolves showed considerable diversity and supported the hypothesis that wolves were the ancestors of dogs, suggesting that dogs originated more than 100,000 years before the present.
Mitochondrial DNA phylogeography and population history of the grey wolf Canis lupus
The results suggest that fluctuating population sizes during the late Pleistocene have left a genetic signature on levels of variation in both species, and a statistical parsimony analysis indicates local genetic structure that suggests recent restricted gene flow.
Genome Sequencing Highlights the Dynamic Early History of Dogs
It is found that none of the extant wolf lineages from putative domestication centers is more closely related to dogs, and, instead, the sampled wolves form a sister monophyletic clade, suggesting that a re-evaluation of past hypotheses regarding dog origins is necessary.
Ancient DNA Evidence for Old World Origin of New World Dogs

Mitochondrial DNA sequences isolated from ancient dog remains from Latin America and Alaska showed that native American dogs originated from multiple Old World lineages of dogs that accompanied late…

It is shown here that the genetic diversity of the severely bottlenecked and geographically isolated Scandinavian population of grey wolves (Canis lupus), founded by only two individuals, was recovered by the arrival of a single immigrant.
Widespread origins of domestic horse lineages.
Domestication entails control of wild species and is generally regarded as a complex process confined to a restricted area and culture. Previous DNA sequence analyses of several domestic species have…
Megafaunal Extinctions and the Disappearance of a Specialized Wolf Ecomorph
Identification of Genomic Regions Associated with Phenotypic Variation between Dog Breeds using Selection Mapping
This study provides a catalogue of genomic regions showing extreme reduction in genetic variation or population differentiation in dogs, including many linked to phenotypic variation.
Ebola Outbreak Killed 5000 Gorillas

- 8 December 2006
Data is presented suggesting that in 2002 and 2003 ZEBOV killed about 5000 gorillas in the study area, evidence that group-to-group transmission has amplified gorilla die-offs.
FAST TRACK: Legacy lost: genetic variability and population size of extirpated US grey wolves (Canis lupus)
Analysis of mitochondrial DNA sequences of 34 pre‐extermination wolves found that they had more than twice the diversity of their modern conspecifics, implying a historic population size of several hundred thousand wolves in the western cUS and Mexico, and a much wider geographical mandate for the reintroduction of Mexican wolves than currently planned.
