Compared to wolf and dog pups, golden jackal pups develop aggression at the age of 4–6 weeks, when play-fighting frequently escalates into uninhibited biting intended to harm. This aggression ceases by 10–12 weeks when a hierarchy has formed. [107] Once the lactation period concludes, the female drives off the pups.
For the first time in 150 years, a new species of canine has been discovered. What was originally thought to be a golden jackal -- has now been confirmed by researchers to be a new type of wolf ...
The African wolf was previously classified as an African variant of the golden jackal, though a series of analyses on the species' mitochondrial DNA and nuclear genome in 2015 demonstrated that it is a distinct species more closely related to the gray wolf and coyote.
Illustration of golden jackal-African wolf hybrids bred in captivity (1821). The Ethiopian wolf's conservation is threatened by dog hybridisation. [22] Animals resulting from Ethiopian wolf-dog hybridisation tend to be more heavily built than pure wolves, and have shorter muzzles and different coat patterns. [23]
Although no genetic evidence has been found of grey wolf–jackal hybridization in the Caucasus Mountains, some cases exist where apparently genetically pure golden jackals have displayed remarkably grey wolf-like phenotypes, to the point of being mistaken for wolves by trained biologists. [7]
The gray wolf (C. lupus), the Ethiopian wolf (C. simensis), eastern wolf (C. lycaon), and the African golden wolf (C. lupaster) are four of the many Canis species referred to as "wolves". [37] Species that are too small to attract the word "wolf" are called coyotes in the Americas and jackals elsewhere. [38]
The Egyptian wolf had an unresolved taxonomic identity and was formerly known as the Egyptian jackal. Throughout much of the 20th century, the animal was classed as a subspecies of golden jackal, Canis aureus lupaster. Notice was however taken by numerous zoologists of the animal's morphology, which corresponds more to that of the grey wolf.
Jackals are canids native to Africa and Eurasia.While the word "jackal" has historically been used for many canines of the subtribe canina, in modern use it most commonly refers to three species: the closely related black-backed jackal (Lupulella mesomelas) and side-striped jackal (Lupulella adusta) of Central and Southern Africa, and the golden jackal (Canis aureus) of south-central Europe ...
