A 2007 study of feline mitochondrial DNA and microsatellites of approximately 1,000 cats from many different regions (including Africa, Azerbaijan, Kazakhstan, Mongolia, and the Middle East) showed 5 genetic lineages of the wildcat population. [5] These lineages included: Felis silvestris silvestris [6] (Europe) Felis silvestris bieti [7] (China)
