Etymology

Lorenz Oken Lorenz Oken (1 August 1779 – 11 August 1851) was a German naturalist, botanist, biologist, and ornithologist. Oken was born Lorenz Okenfuss (german: Okenfuß) in Bohlsbach (now part of Offenburg), Ortenau, Baden, and studied natural history and ...
, in the third volume of his ''Lehrbuch der Naturgeschichte'' (1815), to place these species into a new separate genus, ''Thos'', named after the classical Greek word "jackal", but his theory had little immediate impact on taxonomy at the time. Angel Cabrera, in his 1932 monograph on the mammals of Morocco, questioned whether or not the presence of a cingulum on the upper molars of the jackals and its corresponding absence in the rest of ''Canis'' could justify a subdivision of that genus. In practice, Cabrera chose the undivided-genus alternative and referred to the jackals as ''Canis'' instead of ''Thos''. Oken's ''Thos'' theory was revived in 1914 by
Edmund Heller Edmund Heller (May 21, 1875 – July 18, 1939) was an American zoologist. He was President of the Association of Zoos & Aquariums for two terms, from 1935-1936 and 1937-1938. Early life While at Stanford University, he collected specimens in th ...

Species


Folklore and literature

Like foxes and coyotes, jackals are often depicted as clever sorcerers in the myths and legends of their regions. They are mentioned roughly 14 times in the Bible. It is frequently used as a literary device to illustrate desolation, loneliness, and abandonment, with reference to its habit of living in the ruins of former cities and other areas abandoned by humans. It is called "wild dog" in several translations of the Bible. In the King James Bible, Isaiah 13:21 refers to 'doleful creatures', which some commentators suggest are either jackals or
