The Indian plains wolf (Canis lupus pallipes, synonym Canis indica) is formed by 2 closely related female lineage mitochondrial DNA (mDNA) haplotypes that fall within the Canis lupus pallipes subspecies of the gray wolf. It is only found in the arid and semi-arid peninsular plains of India. These lineages are genetically unique from all other wolves worldwide, including from other wolves forming C. l. pallipes. The Indian gray wolf and the Himalayan wolf are phylogenetically basal to all other wolves and are closer to the African golden wolf. This indicates that these are the descendants of an ancient wolf distribution. In April 2009, the Latin binomial Canis indica had been proposed for these 2 haplotypes as a nomenclatural and taxonomic split from Canis lupus as a new species through the Nomenclature Specialist on the CITES Animals Committee. The committee recommended against this proposal but recommended that the name be entered into the species database as a synonym of the name under which it was listed. The proposal was based on one study that relied on only a limited number of museum and zoo samples that may not have been representative of the wild population, and a call for further fieldwork was made.:886

Wolf
The wolf must give chase and gain on its fleeing prey, slow it down by biting through thick hair and hide, and then disable it enough to begin feeding.[117] After chasing and then confronting a large prey animal, the wolf makes use of its 6 cm (2 1⁄2 in) fangs and its powerful masseter muscles to deliver a bite force of 28 kg/cm2 (400 lbf/in2), which is capable of breaking open the skulls of many of its prey animals. The wolf leaps at its quarry and tears at it. One wolf was observed being dragged for dozens of metres attached to the hind leg of a moose; another was seen being dragged over a fallen log while attached to a bull elk’s nose.[116]

The most common point of wolf attacks on moose is the upper hind legs.[124][125][126] Hind leg wounds are inflicted from the rear, midway up the hock with the canine teeth. These leave gaping skin perforations over 4 cm (1 1⁄2 in) in diameter. Although blood loss, muscle damage, and tendon exposure may occur, there is no evidence of hamstringing. Attacks also occur on the fleshy nose, the back and sides of the neck, the ears, and the perineum.[126] Wolves may wound large prey and then lie around resting for hours before killing it when it is weaker due to blood loss, thereby lessening the risk of injury to themselves.[127]

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 ...
