Pottok the Losino, the Galician, the Landais, and the Monchino horses. Tests have revealed considerable genetic differences between populations in the Northern Basque Country and the Southern Basque Country, leading some to consider them separate breeds. Some claim the Pottok's origins derive from the horses on ancient cave paintings in the area and thus claim to descend from the Magdalenian horses of 14,000–7000 BC. Other link its origins to an influx of horses during the Bronze Age. However, neither of these theories has to date been scientifically verified.

Animal genetic resources for food and agriculture to wild. They differ in terms of animal management, animal treatment, environmental impact, and market infrastructure. For some breeds, opportunities for sustainable use are limited. For such breeds, to ensure that their critical genetic diversity is not lost, conservation programs are required. Several approaches for conservation can be applied, including in situ conservation with live animal populations, and ex situ conservation or cryoconservation involving the freezing of genetic materials. In many instances, both of these approached are used in a complementary manner. In order to establish and strengthen these programs, more research on methods and technologies must be undertaken, especially
