Yamna culture
(重定向自Yamnaya)
The Yamna or Yamnaya culture, also called Pit Grave Culture and Ochre Grave Culture, was a late Copper Age/early Bronze Age culture of the Southern Bug/Dniester/Ural region (the Pontic steppe), dating to 3,500 – 2,300 BCE. The Yamna culture is identified with the late Proto-Indo-Europeans, and is the strongest candidate for the Urheimat (homeland) of the Proto-Indo-European language.
