Thetarpan(Equus ferus ferus) was a free-ranging horse subspecies of theEurasian steppefrom the 18th to the 20th century.[1]It is generally unknown whether those horses represented genuine wild horses, feral domestic horses or hybrids.[1]The last individual believed to be a tarpan died in captivity in theRussian Empirein 1909.[2]
Beginning in the 1930s, several attempts were made to develop horses that looked like tarpans throughselective breeding,called "breeding back"by advocates. The breeds that resulted included theHeck horse,theHegardt or Stroebel's horse ,and a derivation of theKonikbreed, all of which have a primitive appearance, particularly in having thegrullocoat colour. Some of these horses are now commercially promoted as "tarpans", although such animals are only domestic breeds and not the wild animal themselves.
Name and etymology
[edit]The name "tarpan" or "tarpani" derives from aTurkic language(KazakhorKyrgyz) name meaning "wild horse".[3][4]TheTatarsand theCossacksdistinguished the wild horse from theferal horse;the latter was calledTakjaorMuzin.[5][6]
Taxonomy
[edit]The tarpan was first described bySamuel Gottlieb Gmelinin 1771;[7]he had seen the animals in 1769 in the district ofBobrov,nearVoronezh.In 1784,Pieter Boddaertnamed the speciesEquus ferus,referring to Gmelin's description. Unaware of Boddaert's name,Otto Antoniuspublished the nameEquus gmeliniin 1912, again referring to Gmelin's description. Since Antonius' name refers to the same description as Boddaert's it is ajunior objective synonym.It is now thought that the domesticatedhorse,namedEquus caballusbyCarl Linnaeusin 1758, is descended from the tarpan; indeed, many taxonomists consider them to belong to the same species. By a strict application of the rules of theInternational Code of Zoological Nomenclature,the tarpan ought to be namedE. caballus,or if considered a subspecies,E. caballus ferus.However, biologists have generally ignored the letter of the rule and usedE. ferusfor the tarpan to avoid confusion with the domesticated subspecies.[citation needed]
It is debated if the small, free-roaming horses seen in the Russian steppes during 18th and 19th centuries and called "tarpan" were indeed wild, never-domesticated horses, hybrids of thePrzewalski's horseand local domestic animals, or simplyferal horses.[8]Most studies have been based on only two preserved specimens and research to date has not positively linked the tarpan to Pleistocene or Holocene-era animals.[citation needed]
In 2003, theInternational Commission on Zoological Nomenclature"conserved the usage of 17 specific names based on wild species, which are predated by or contemporary with those based on domestic forms", confirmingE. ferusfor the undomesticated wild horse. Taxonomists who consider the domestic horse a subspecies of the wild horse should useEquus ferus caballus;the nameEquus caballusremains available for the domestic horse where it is considered to be a separate species.[9]
Appearance
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/2/28/Tarpan.png/220px-Tarpan.png)
Traditionally, two tarpan subtypes have been proposed, the forest tarpan and steppe tarpan, although there seem to be only minor differences in type. The general view is that there was only one subspecies, the tarpan,Equus ferus ferus.[2]The last individual, which died in captivity in 1909, was between 140 and 145 centimetres (55 and 57 in; 13.3 and 14.1hands) tall at the shoulders, and had a thick, fallingmane,agrullocoat colour, dark legs, andprimitive markings,including a dorsal stripe and shoulder stripes.[2]
A number ofcoat colourgenotypeshave been identified within European wild horses from thePleistoceneandHolocene:those creatingbay,blackandleopard complexare known from the wild horse population in Europe and were depicted incave paintingsof wild horses during the Pleistocene.[11]Thedun gene,[12]adilution geneseen inPrzewalski's horsethat also creates the grullo or "blue dun" coat seen in the Konik, has not yet been studied in European wild horses. It is likely that at least some wild horses had a dun coat.[11]
Historical reports are ambiguous on whether tarpans had standing manes like wild equines, or falling manes like domestic horses.[2]
The appearance of European wild horses may be reconstructed with genetic,osteologicand historic data. One genetic study suggests that bay was the predominant colour in European wild horses.[13]During theMesolithic,a gene coding a black coat colour appeared on the Iberian peninsula. This colour spread east but was less common than bay in the investigated sample and never reached Siberia.[13]Bay in combination with dun results in the "bay dun" colour seen in Przewalski's horses; black with dun creates the grullo coat. A loss of the dun dilution may have been advantageous in more forested western European landscapes, as dark colours were a better camouflage in forests.[14]Pangaréor "mealy" coloration, a characteristic of other wild equines, might have been present in at least some European wild horses,[14]as historic accounts report a light belly.
Historic references report that most tarpans were black dun (grullo, "blue dun" ) colour. Some black individuals were reported to have domestic colours like white or grey legs. Authors, such as Peter Pallas, believed tarpans to be escaped farm horses.[15]
History
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/9/9a/Lascaux_horse_replica.jpg/220px-Lascaux_horse_replica.jpg)
Wild horses have been present in Europe since thePleistoceneand ranged from southernFranceandSpaineast to centralRussia.There are cave drawings of primitive predomestication horses atLascaux,France and inCave of Altamira,Spain, as well as artifacts believed to show the species insouthern Russian empire,where a horse of this type was domesticated around 3000 BC.[16]Equus ferushad a continuous range from western Europe toAlaska;historic material suggests wild horses lived in most parts of Holocene continental Europe and the Eurasian steppe, except for parts of Scandinavia, Iceland and Ireland.[15]
Ancient equine DNA
[edit]Tarpan DNA shows its ancestry to be a mixture between horses native to Europe and found with theCorded Ware Culture,and horses closely related to the DOM2 population, the ancestors of modern domestic horses. (DOM2 horses originated from the Western Eurasia steppes, especially the lower Volga-Don, but not in Anatolia, during the late fourth and early third millennia BCE. Their genes may show selection for easier domestication and stronger backs). This is not consistent with tarpans as the wild ancestor of, or a feral version of, DOM2. Nor is the tarpan a hybrid with Przewalski's horses.[17]
Forest tarpan
[edit]The "forest horse" or "forest tarpan" was a hypothesis of various 20th-century natural scientists, includingTadeusz Vetulani,who suggested that the continuous forestation of Europe after the last ice age created forest-adapted subtype of the wild horse, which he namedEquus sylvestris.However, historic references do not describe any major difference between the populations, and therefore most authors assume there was only one subspecies of western Eurasian wild horse,Equus ferus ferus.[2]
Nevertheless, a stocky type of horse living in forests and highlands was described during the 19th century in Spain, thePyrenees,theCamargue,theArdennes,Great Britain,and the southernSwedishupland. They had a robust head and strong body, and a long frizzy mane. The colour was described as faint brown or yellowish brown witheel stripeand leg stripes, or wholly black legs. The flanks and shoulders were spotted, some of them tended to an ashy colour. They dwelled in rocky habitats and showed intelligent and fierce behaviour.[6]Yet, those horses were never colloquially called "tarpans".[18]
Black wild horses were found in Dutch swamps, with a large skull, small eyes, and a bristly muzzle. Their mane was full, with broad hooves, and curly hair. However, it is possible that these were feral and not wild horses.[6]

Herodotusdescribed light-coloured wild horses in an area now part ofUkrainein the 5th century BCE. In the 12th century,Albertus Magnusstated that mouse-coloured wild horses with a dark eel stripe lived in the German territory, and in Denmark, large herds were hunted.
16th century free-ranging horses in Europe
[edit]Wild horses still were common in the east of Prussia during the 15th and early 16th centuries. During the 16th century, wild horses disappeared from most of the mainland of western Europe and became less common in eastern Europe as well.Belsazar Hacquetsaw wild horses in the Polish zoo inZamośćduring theSeven Years' War.According to him, those wild horses were of small body size, had a blackish brown colour, a large and thick head, short dark manes and tail hair, and a "beard". They were absolutely untameable and defended themselves harshly against predators.[citation needed]
Kajetan Kozmian visited the population at Zamość as well and reported that they were small and strong, had robust limbs and a consistently dark mouse colour.Samuel Gottlieb Gmelinwitnessed herds inVoronezhin 1768. Those horses were described as very fast and shy, fleeing at any noise, and as small, with small, pinned ears and a short frizzly mane. The tail was shorter than in domestic horses. They were typically mouse-coloured with a light belly and legs becoming black, althoughgreyand white horses were mentioned as well. The coat was long and dense.[15]The horses at Zamosc were never called "tarpan" back in their lifetime.[18]
Peter Simon Pallaswitnessed possible tarpans in the same year in southern Russia. He thought they were feral animals that escaped during the confusions of wars. These herds were important game of the Tatars and numbered between 5 and 20 animals. The horses he described had a small body, large and thick heads, short frizzly manes and short tail hair, as well as pinned ears. The colour was described as faint brownish, sometimes brown or black. He also reported of obvious domestic hybrids with light-coloured legs orgrey coats.[15]
The tarpans of 18th century Europe
[edit]The Natural History of Horsesby 19th-century authorCharles Hamilton Smithalso described tarpans. According to Smith, the herds of free-ranging horses numbered from a few to hundred individuals.[6]They often were mixed with domestic horses, and alongside pure herds there were herds of feral horses or hybrids. The colour of alleged pure tarpans was described as consistently brown, cream-coloured or mouse-coloured. The short frizzy mane was reported to be black, as were the tail and legs. The ears were of varying size, but set high on the skull. The eyes were small.[15]
According to Smith, tarpans made stronger sounds than domestic horses and the overall appearance of these horses was mule-like.[6]
Extinction
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/8/86/Equus_ferus_ferus.jpg/220px-Equus_ferus_ferus.jpg)
The human-caused extinction of wild horses in Europe began in Southern Europe, possibly in antiquity.[15]While humans had been hunting wild horses since thePaleolithic,[14]during historic timeshorse meatwas an important source of protein for many cultures. As large herbivores, the range of the tarpan was continuously decreased by the increasing human population of the Eurasian landmass. Wild horses were further targeted because they caused damage to hay stores and often took domestic mares from pastures. Furthermore, interbreeding with wild horses was an economic loss for farmers since thefoalsof such matings were intractable.[further explanation needed][15]
Tarpans lived in the southern parts of the steppe. In 1879 the last scientifically confirmed individual was killed. After that, only dubious sightings were documented.[15]As the tarpan horse died out in the wild between 1875 and 1890, the last free-ranging mare considered a tarpan was accidentally killed during an attempt at capture. The last captive tarpan died in 1909 in a Ukrainian zoo in the Russian empire.[20]
The horses at Zamosc survived until 1806, when they were allegedly donated to local farmers of Poland and bred to their horses.[2][21]TheKonikis claimed to descend from these hybrid horses,[16]as recent research has highlighted a significant degree of anatomic difference between free-roaming Konik in the Netherlands and other modern domesticated horses.[22]
Tarpans interbreeding with domestic horses
[edit]The oldest archaeological evidence for domesticated horses is from Kazakhstan and Ukraine between 6,000 and 5,500YBP(years before present).[23]The diversemitochondrial DNAof domestic horses contrasts sharply with the very low diversity of the Y chromosome; that suggests that many mares but only a few stallions were used,[24]and local use of wild mares or even secondary sites of domestication are likely.[25]Therefore, the European wild horse may well have contributed to the domestic horse.[25]
Wild horses vs. feral horses
[edit]Some researchers consider the tarpans to be mixed wild and feral population or completely feral horses. Few consider the more recent animals historically called "tarpans" to be genuine wild horses without domestic influence.[15]Historic references to "wild horses" may actually refer to feral domestic horses or hybrids.[15]
Some 19th century authors wrote that local "wild" horses had hoof problems that led to crippled legs; therefore, they assumed these were feral horses.[15]Other contemporary authors claimed all "wild" horses between the Volga River and the Ural were actually feral. However, others thought that this was too speculative and assumed that wild, undomesticated horses still lived into the 19th century.[6]Domestic horsesused in warfareoften were turned loose when they were no longer needed. Also, remaining wild stallions could steal domestic mares. There are some accounts from the 18th and 19th centuries of wild herds with typical wild horse features such as large heads, pinned ears, short frizzy mane and tail, but mentioned animals with domestic influence as well.[15]
The only known individual to be photographed was the so-called Cherson tarpan, which was caught as a foal nearNovovorontsovkain 1866. It died in 1887 in the Moscow Zoo. The nature of this horse was dubious in its lifetime, because it showed almost none of the wild horse features described in the historic sources.[2]In 2021, a study found that the so-called 'Shatilov' tarpan, a museum specimen from theKherson regionof thePontic–Caspian steppethat died in 1868[citation needed],was a hybrid between two horse lineages, with two thirds of its genetics representing the same ancestral lineage as modern horses, and the remaining third related to a distinct lineage of European horses found at an archaeological site associated with the late-NeolithicCorded Ware culture.[26]

Breeding back the tarpan
[edit]Three attempts have been made to useselective breedingto create a type of horse that resembles the tarpanphenotype,though recreating an extinct subspecies is not genetically possible with current technology. In 1936, Polish university professorTadeusz Vetulaniselected Polish farm horses that were formerly known as Panje horses (now called Konik) and that he believed resembled the historic tarpan and started aselective breedingprogram. Although his breeding attempt is well known, it made only a minor contribution to the modernKonikstock,[1]which clusters genetically with other domestic horse breeds, including those as diverse as theMongolian horseand theThoroughbred.[25]
In the early 1930s,Berlin ZooDirectorLutz HeckandHeinz Heckof theMunich Zoobegan a program crossbreedingKonikswithPrzewalski horsestallions, and the mares ofGotland ponies,andIcelandic horses,. By the 1960s they produced theHeck horse.[27]In the mid-1960s, Harry Hegard started a similar program in the United States usingmustangsand local working ranch horses that has resulted in the Hegardt or Stroebel's horse.[28]
Assessment
[edit]While all three breeds have a primitive look that resembles the tarpan in some respects, they are not genetically tarpans and the wild, predomestic European horse remains extinct. However, this does not prevent some modern breeders from marketing horses with these features as a "tarpan".[29]
In spite of sharing primitive external features, the Konik andHuculhorses have markedly differentconformationwith differently proportioned body measurements, thought in part to be linked to living in different habitats.[2][30]
Other breeds sometimes alleged to be surviving wild horses include theExmoor ponyand theDülmen pony.However, genetic studies do not set any of these breeds apart from other domestic horses.[25][31]On the other hand, there has not yet been a study comparing domestic breeds directly with the European wild horse.[32]
