In the 19th century, in Abkhazia, a region of the Caucasus under the rule of the Russian Empire, a young woman with a beast-like appearance was captured in the forest. The woman, named Zana, showed abnormally low physical and intellectual abilities for a human, but she would end up living out her life in the village. For many years, her existence has been linked to the Caucasus folklore "Almasti" and passed down through the generations. Was she a Neanderthal? Or an unknown ape that we do not know? The latest DNA analysis will reveal her true identity.
