As of 2018, the global gray wolf population is estimated to be 200,000–250,000. [1] Once abundant over much of North America and Eurasia, the gray wolf inhabits a smaller portion of its former range because of widespread human encroachment and destruction of its habitat, and the resulting human-wolf encounters that sparked broad extirpation.
It was estimated that the African wolf diverged from the wolf–coyote clade 1.0–1.7 million years ago, during the Pleistocene, and therefore its superficial similarity to the golden jackal (particularly in East Africa, where African wolves are similar in size to golden jackals) would be a case of parallel evolution.
Wolves in the eastern Balkans benefitted from the region's contiguity with the former Soviet Union and large areas of plains, mountains and farmlands. Wolves in Hungary occurred in only half the country around the start of the 20th century, and were largely restricted to the Carpathian Basin. Wolf populations in Romania remained largely ...

The cranial length of the adult Arabian wolf measures on average 200.8 mm (0.659 ft), which is smaller than most wolves. [15] Along with the Indian wolf, it is probably smaller than other wolves to help it adapt to life in a hot, dry climate. [16] This is an example of Bergmann's rule, where mammal size varies by the warmth of their environment.
