“…Concurrently with North‐Caucasus Majkop culture (5,850–4,850 BP), recognized as the putative homeland of the Northwestern Caucasian language family (walnut proto‐term *ĺa , Wang et al., 2019), a wide variety of plant foods including, grape ( Vitis vinifera ), hazelnut ( Corylus ), common walnut, and sweet chestnut were stored in ceramic vessels as offerings for votive/ritual purpose in the geographically adjacent settlements of the Kura‐Araxes culture in the Southern Caucasus (Areni‐1 Cave, Armenia 6,230–5,790 BP, Wilkinson et al., 2012; Aradetis Orgora, Georgia, 4,950 BP, Kvavadze et al., 2019). While it is still matter of debate if Kartvelian was the idiom spoken by Kura‐Axes communities (Beridze, 2019, walnut proto‐term *ḳaḳ‐al‐, chestnut proto‐term *ć̣ab‐ ), the subsequent Indo‐European speakers of the Early Kurgan settlements in Georgia showed similar habits using animals, cereals, hazelnuts, figs ( Ficus carica L.), walnuts (Indo‐European proto‐form *kar and *a‐/an‐gōza ), and chestnuts (Indo‐European proto‐form *kastAno‐ and *blwt' ) as major components of funeral gifts (Bedeni Plateau, 4,450–4,150 BP, Kvavadze et al., 2015; Ananauri‐3‐kurgan site, 4,450 BP, Makharadze, 2015). All these studies suggested that common walnut and sweet chestnut cultivation, together with viticulture and pasturing, was fully incorporated in the Trans‐Caucasian agricultural landscape of EBA.…”
