TL;DR: Comparing population genetic results of humans and dogs from Siberia, Beringia, and North America shows that there is a close correlation in the movement and divergences of their respective lineages, and suggests that dogs were domesticated in Siberia by ∼23,000 y ago, possibly while both people and wolves were isolated during the harsh climate of the Last Glacial Maximum.

TL;DR: The results show that, though the four specimens represent extinct wolf lineages, they do not form a monophyletic group, and each Pleistocene Siberian canid branched off the lineage that gave rise to present-day wolves and dogs.

TL;DR: This analysis indicates that sled dogs represent an ancient lineage going back at least 9500 years and that wolves bred with the ancestors of sled dogs and precontact American dogs, however, gene flow between sled Dogs and wolves likely stopped before ∼9500 years ago.

TL;DR: Genetic data is used to determine the sex of 98 woolly mammoth specimens in order to infer social and behavioral patterns in the last 60,000 years of the species' existence and hypothesize that social structure in proboscideans is characterized by matriarchal hierarchy and sex segregation.

TL;DR: 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.
