"The history of the Indo-European words for 'horse' shows that the Proto-Indo-European speakers had long lived in an area where the horse was native and/or domesticated (Mallory 1989,pp.161–63). The first strong archaeological evidence for the domestication of the horse comes from the Ukrainian Srednij Stog culture, which flourished c. 4200–3500 BC and is likely to represent an early phase of the Proto-Indo-European culture (Anthony 1986:295f.; Mallory 1989:162, 197–210). During the Pit Grave culture (c. 3500–2800 BC) which continued the cultures related to Srednij Stog and probably represents the late phase of the Proto-Indo-European culture – full-scale pastoral technology, including the domesticated horse, wheeled vehicles, stockbreeding and limited horticulture, spread all over the Pontic steppes, and, c. 3000 BC, in practically every direction from this centre (Anthony 1986, 1991; Mallory 1989, vol. 1).
