Немного о затруднениях таксономии собачьих:

Canid species are largely well defined, though there is debate over whether the Dingo represents a Grey Wolf subspecies or an entirely seperate species, and some authorities consider Eastern North American populations of the Grey Wolf to be a distinct species, Canis Lycaon. In early 2011, genetic analysis showed that certain Golden Jackal populations from Egypt to Ethiopia actually represent an ancient Grey Wolf subspecies that should be reclassified as the African Wolf. At the other extreme, the very similar Kit Fox and Swift Fox are sometimes classified as the same species.

Ну и раз уж заговорили про африканского волка:

It was previously classified as an African variant of the Eurasian Golden Jackal, with at least one subspecies (Canis anthus lupaster) having been classified as a Grey Wolf. In 2015, a series of analyses on the species' mtDNA and nuclear genome demonstrated that it was in fact distinct from the golden jackal, and more closely related to Grey Wolves and Coyotes. It is nonetheless still close enough to the golden jackal to produce hybrid offspring, as indicated through genetic tests and a 19th century captive crossbreeding experiment. As the IUCN's golden jackal page has not been updated since 2008, it has yet to recognise the distinctiveness of the African wolf and give it its own conservation status, with population estimates being completely lacking.

Африканские волки ближе к волкам с койотами, чем к шакалам.

Although subsequently synonymised with the golden jackal, new doubts over its being conspecific with the golden jackal arose in 2011, when several golden "jackal" populations in Egypt and the Horn of Africa classed as Canis aureus lupaster were found to have mtDNA sequences more closely resembling those in Grey Wolves than those of golden jackals. These wolf-like mtDNA sequences were confirmed to occur over a range 6,000 km wide, encompassing Algeria, Mali and Senegal. In both these studies, it was proposed to reclassify Canis aureus lupaster as a subspecies of Grey Wolf.

In 2015 however, a more thorough comparative study of mitochondrial and nuclear genomes on both Eurasian Golden Jackals and their African counterparts revealed that the latter were in fact a separate species more closely related to Grey Wolves and Coyotes, with a genetic divergence of around 6.7%, which is greater than that between Grey Wolves and Coyotes (4%) and that between Grey Wolves and domestic dogs (0.2%).

It was estimated that the African golden wolf diverged from the wolf-coyote clade 1-1.7 million years ago during the Pleistocene, and that its superficial similarity to the Eurasian Golden Jackal (particularly in East Africa, where African wolves are similar in size to golden jackals) is a case of parallel evolution.

Похож на шакала. Но так как вопрос с подвохом, значит африканский волк. -)

А, вообще, фиг их отличишь.



Вот скажи, кто есть кто?

А вот и не угадал! Слева - африканский волк, справа - шакал. :d

Да не может такого быть.

Это наверное в том ключе что все африканские обыкновенные шакалы по новому - волки... , а так судя по фото, слева африканский подвид шакала, справа индийский

Same or different? The African golden wolf, Canis anthus, (left) and Eurasian golden jackal, C. aureus (right), were originally thought to be the same species, formerly known as the golden jackal.
