Origins

Arabians are thought to be one of the oldest human-developed horse breeds in the world. Recent genetic studies of mitochondrial DNA in Arabian horses of Polish and American breeding suggest that the modern breed has heterogeneous origins with ten haplogroups. The modern concept of breed purity in the modern population cannot be traced beyond 200 years.

The progenitor stock, the Oriental subtype, had characteristics similar to the modern Arabian. Horses with these features appeared in rock paintings and inscriptions in the Arabian Peninsula dating back 3500 years. In ancient history throughout the Ancient Near East, horses with refined heads and high-carried tails were depicted in artwork, particularly that of Ancient Egypt in the 16th century BC.

Some 20th-century scholars of the Arabian horse once theorized that the Arabian came from a separate subspecies of horse, known as equus caballus pumpelli. However, others, including Gladys Brown Edwards, a noted Arabian researcher, stated that the "dry" oriental horses of the desert, from which the modern Arabian developed, were Equus ferus caballus with specific landrace characteristics based on the environments in which they lived, rather than being a separate subspecies. Horses with similar, though not identical, physical characteristics include the Marwari horse of India, the Barb of North Africa, the Akhal-Teke of western Asia and the now-extinct Turkoman Horse.
