Once thought to possibly be C. l. pallipes (the Indian wolf), the Arabian wolf was designated Canis lupus arabs by the British zoologist Reginald Innes Pocock in 1934. Pocock noted its smaller skull and smaller size. In the third edition of Mammal Species of the World published in 2005, the mammalogist W. Christopher Wozencraft listed under the wolf Canis lupus the subspecies Canis lupus arabs. A 2014 study suggests that genetically the Arabian wolf is closer to C. l. lupus than it is to C. l. pallipes and supports the subspecies designation C. l. arabs. There has been admixture with domestic dogs, but it is unclear whether or not this is why this wolf is genetically closer to C. l. lupus. This raises a concern of extinction by hybridization as Arabian wolves are more adapted to desert life than wolf/dog hybrids.

In Israel and the Palestinian Territories, there is some disagreement as to the exact taxonomic status of wolves. Some scientists hold that two subspecies of wolf are present- C. l. pallipes in the northern parts, and C. l. arabs in the south. They point out that the southern wolves are smaller than the northern wolves which are also darker and have longer fur. Other scientists consider the wolf in the area to be C. l. arabs, with no real distinction between northern and southern wolves. As in other countries, there is interbreeding with feral dogs, which adds an element of uncertainty.

Wolf
The wolf is the largest member of the Canidae family, and is further distinguished from coyotes and jackals by a broader snout, shorter ears, a shorter torso and a longer tail. It is slender and powerfully built with a large, deeply descending rib cage, a sloping back, and a heavily muscled neck. The wolf’s legs are moderately longer than those of other canids, which enables the animal to move swiftly, and to overcome the deep snow that covers most of its geographical range in winter. The ears are relatively small and triangular. The wolf’s head is large and heavy, with a wide forehead, strong jaws and a long, blunt muzzle. The skull is 230–280 mm (9–11 in) in length and 130–150 mm (5–6 in) in width. The teeth are heavy and large, making them better suited to crushing bone than those of other canids. They are not as specialized as those found in hyenas though. Its molars have a flat chewing surface, but not to the same extent as the coyote, whose diet contains more vegetable matter. Females tend to have narrower muzzles and foreheads, thinner necks, slightly shorter legs, and less massive shoulders than males.

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 ...
