As of July 2017, approximately 31 wild Mexican gray wolves inhabited Chihuahua and Sonora, Mexico, in the northern Sierra Madre Occidental. As of November 2017, 114 Mexican gray wolves were living in the wild in Arizona and New Mexico, distributed in 22 packs across the two states.

In February 2018, five more wolves were released in Chihuahua, bringing the total wild population in Mexico (Sonora and Chihuahua) to thirty-seven wolves. In 2018, six Mexican wolf pups from the Endangered Wolf Center were sent to dens in Arizona and New Mexico for their survival.

In 2019, the U.S. Fish and Wildlife Services discovered that 52 of 90 wolf pups born earlier in 2018 had survived to adulthood. These new wolves brought the number of Mexican gray wolves in Arizona and New Mexico to 163, with 87 wolves in New Mexico and 76 in Arizona.

Eight Mexican wolf cubs were born at the Desert Museum in Saltillo, Coahuila on July 1, 2020.

Evolution of the wolf
During the same period, the Soya Strait between Hokkaido and Sakhalin Island was dry for 75,000 years and it was proposed that the extinct Ezo wolf (C. l. hattai) arrived on Hokkaido from Sakhalin.[132][114][133] However, the sequences indicated that it arrived in Hokkaido less than 10,000 YBP. The Ezo wolf was closely related to one of the North American clades,[132][114][134] but different to the more southerly Japanese wolf (C. l. hodophilax) that was basal to modern wolves.[132][114] The Japanese wolf inhabited Kyushu, Shikoku, and Honshu islands[135][136] but not Hokkaido Island.[136] This indicates that its ancestor may have migrated from the Asian continent through the Korean Peninsula into Japan.[132][136] The past sea levels of the Korean Strait together with the timing of the Japanese wolf sequences indicated that it arrived to the southern islands less than 20,000 YBP.[114]

The dog was a very successful invader of North America and had established a widespread ecological niche by the Early–Middle Holocene. There was no overlap in niche between the dog and the wolf in comparison to the dog and other North American canids. By the Late Holocene, the dog’s niche area was less in size than researchers had expected to find, indicating that it was limited by biotic factors. These regions include the northeast and northwest of the United States that correlate with the greatest densities of early human occupation, indicating that the dog had “defected” from the wolf niche to the human niche and explains why the dog’s niche area was not as large as expected. The separation between dog and wolf may reflect the rapid rate in which domestication occurred,[137] including the possibility of a second domestication event occurring in North America.[138][137] Packs of wolves and hunter-gatherers hunt similar prey in a similar way within a similar group social structure that may have facilitated wolf domestication.[139]

In 2016, a whole-genome DNA study proposed, based on the assumptions made, that all of the North American wolves and coyotes diverged from a common ancestor less than 6,000–117,000 years ago, including the coyote diverging from Eurasian wolf about 51,000 years ago (which matches other studies indicating that the extant wolf came into being around this time), the red wolf diverging from the coyote between 55,000–117,000 years ago, and the eastern wolf (Great Lakes region and Algonquin) wolf diverging from the coyote 27,000-32,000 years ago, and asserts that these do not qualify as an ancient divergences that justify them being considered unique species. The study also indicated that all North America wolves have a significant amount of coyote ancestry and all coyotes some degree of wolf ancestry, and that the red wolf and eastern wolf are highly admixed with different proportions of gray wolf and coyote ancestry. The study found that coyote ancestry was highest in red wolves from th...

In Italy, the earliest remains of a wolf (Canis lupus) have been found in 1984 at the Middle Pleistocene site of La Polledrara di Cecanibbio, 20 km north-west of Rome in deposits dated 340-320 thousand years ago. The genetic analysis of Apennine wolves indicates that they went through a population decline of 100–1,000 fold between the past 4,700–23,800 years, which indicates genetic isolation south of the alps from other wolf populations for many thousands of years. In 1992, an examination of the mitochondrial DNA (mDNA) of 26 grey wolf populations worldwide revealed that the Italian wolf has a unique mitochondrial haplotype (a mutation) not shared by any other grey wolf population. Further tests on grey wolf mDNA revealed that, unlike several European grey wolf populations, Italian wolves do not share haplotypes with either other grey wolves or domestic dogs. In 2010, a study compared the mDNA haplotypes of 24 ancient wolf specimens from Western Europe dated between 44,000 and 1,2...

Wolf populations in Poland have increased to about 800–900 individuals since being classified as a game species in 1976. Poland plays a fundamental role in providing routes of expansion into neighbouring Central European countries. In the east, its range overlaps with populations in Lithuania, Belarus, Ukraine, and Slovakia. A population in western Poland expanded into eastern Germany and in 2000 the first pups were born on German territory. In 2012, an estimated 14 wolf packs were living in Germany (mostly in the east) and a pack with pups has been sighted within 24 kilometres (15 mi) of Berlin. The grey wolf is protected in Slovakia, though an exception is made for wolves killing livestock. A few Slovakian wolves disperse into the Czech Republic, where they are afforded full protection. Wolves in Slovakia, Ukraine and Croatia may disperse into Hungary, where the lack of cover hinders the buildup of an autonomous population. Although wolves have special status in Hungary, they may ...
