Tarpan

The tarpan, scientifically known as Equus ferus ferus, was a population of free-ranging horses. They lived across the Eurasian steppe from the 18th to the 20th century.

Today, the exact nature of the tarpan remains a subject of intense scientific debate. Researchers are unsure if they were truly wild horses or feral domesticated horses. Some evidence suggests they might have been hybrids. However, DNA sequencing indicates that at least some tarpans were genetically distinct from modern domestic horses. This mystery makes the tarpan a vital subject for studying horse evolution.

Understanding the tarpan requires looking at its physical appearance and genetic makeup.

Most historical reports describe a horse with a primitive look. They often possessed a grullo coat, which is a "blue dun" color. This color is created when a black coat is diluted by a dun gene. Many individuals also had dark legs and distinct markings. These included a dorsal stripe along the spine and stripes on the shoulders. Some accounts even mention a light-colored belly, a trait known as pangaré or "mealy" coloration.

Taxonomy, or the science of naming organisms, provides different views on the tarpan. Samuel Gottlieb Gmelin first described the animal in 1771 after seeing them in 1769. In 1784, Pieter Boddaert named the species Equus ferus. Later, in 1912, Otto Antonius published the name Equus gmelini. Because Antonius used the same description, his name is considered a junior objective synonym. Many taxonomists believe domestic horses, Equus caballus, descended from the tarpan. Because of this link, some scientists classify them as the same species. They might use the name Equus ferus caballus to show this relationship.

The history of wild horses in Europe stretches back to the Pleistocene era. Evidence of primitive horses can be seen in the cave paintings at Lascaux in France and Altamira in Spain. Wild horses once had a continuous range from Western Europe all the way to Alaska. By the 16th century, wild horses began to disappear from mainland Western Europe. They became much less common in Eastern Europe as well. By the 18th century, they were mostly found in the eastern regions like the Russian steppes.

Different researchers have proposed different types of these horses. Some scientists suggested a "forest tarpan" or Equus sylvestris lived in forested areas. They believed these horses were adapted to different environments after the last ice age. However, most authors today assume there was only one subspecies: Equus ferus ferus. Descriptions of stocky horses in places like the Pyrenees or Great Britain exist, but they were not called tarpans. In the 19th century, observers like Belsazar Hacquet saw small, untameable horses in Poland. These animals had thick heads and short, dark manes.

The disappearance of the tarpan was caused by human activity. People hunted wild horses for meat, which was a vital source of protein. As the human population grew, the range for large herbivores like the tarpan decreased. Farmers also viewed them as a threat to their resources. Tarpans would eat hay stores meant for domestic animals. They also sometimes took domestic mares from pastures. Furthermore, interbreeding with domestic horses caused a loss of the wild genetic line. The last known individual died in captivity in the Russian Empire in 1909.

Since the 1930s, people have tried to recreate the look of the tarpan. This process is called "breeding back," which uses selective breeding to achieve a primitive appearance. This effort resulted in breeds like the Heck horse and certain versions of the Konik breed.

While some people commercially sell these horses as "tarpans," they are actually domesticated breeds. They are not the original wild animals themselves. Studying these attempts helps scientists understand how much of the original wild horse identity remains in modern breeds.
