 The relationship between the Sorraia and other breeds remains largely undetermined , as is its relationship to the wild horse subspecies , the Tarpan and the Przewalski 's Horse . The Sorraia originally developed in the southern part of the Iberian peninsula. d 'Andrade hypothesized that the Sorraia would be the ancestor of the Southern Iberian breeds . Morphologically , scientists place the Sorraia as closely related to the Gallego and the Asturcon , but genetic studies using mitochondrial DNA show that the Sorraia forms a cluster that is largely separated from most Iberian breeds . Some evidence links this cluster with Konik and domestic Mongolian horses . At the same time , one of the maternal lineages is shared with the Lusitano . Genetic evidence has not supported an hypothesis that the Sorraia is related to the Barb horse , an African breed introduced to Iberia by the Moors .
