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 breeding In the United States, a backyard breeder is someone who breeds animals, often without registration and with a focus on profit. In some cases the animals are inbred narrowly for looks with little regard to health. The term is considered derogatory. If a backyard dog breeder has a significant number of breeding animals, they become associated with puppy mills. Most puppy mills are licensed with the USDA. Animal breeding Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock.
