Studies of modern gray wolves have identified distinct sub-populations that live in close proximity to each other. However, the geographic origin of this radiation is not known.

Population structure Ina genetic study found that the wolf population in Europe was divided along a north-south axis and formed five major clusters. Three clusters were identified occupying southern and central Europe in Italy, the Dinaric- Balkansthe Carpathians.

Another two clusters were identified occupying north-central Europe and the Ukrainian steppe. The Italian wolf consisted of an isolated population with low genetic diversity. Wolves from Finland, Latvia, Belarus, Poland and Russia formed the north-central Europe cluster, with wolves from the Carpathians cluster coming from a mixture of wolves from the north-central cluster and the Dinaric-Balkans cluster.

The wolves from the Carpathians were more similar to the wolves from the Pontic-Caspian Steppe than they were to wolves from north-central Europe. These clusters may have been the result of expansion from glacial refugiaan adaptation to local environments, and landscape fragmentation and the killing of wolves in some areas by humans.

The studies found that precipitation and mean diurnal temperature range were the most influential variables. The first is the product of a male wolf and a female spanielwhile the latter comes from a female wolf and a male West Siberian Laika It was once thought that dogs and gray wolves did not voluntarily interbreed in the wild, though they can produce fertile wolf-dog offspring.

The coyote is a typical canid intermediate in size between the foxes and the gray wolf. The pelage of the coyote is grayish, buff, pinkish cinnamon, or brownish, or a combination of those colors, often overlain by blackish tipped hairs on the ears, muzzle feet, and dorsum.

Gray wolves howl to assemble the pack (usually before and after hunts), to pass on an alarm (particularly at a den site), In , a comprehensive study found that the gray wolf was present across all of mainland China, both in the past and today.
