The Noua-Wietenberg fusion influenced G?va, and all Channelled Ware groups being primarily descendants from G?va. Channelled Ware seems to have been, in my opinion, by and large Thracian. All post-Channelled Ware territories, in which they firmly established themselves, appear later as Thracian, Dacian and Moesian. No exception from that rule.
There were however some mixed groups and fusions, which turned out different. One of these were the Paeonians, Northern Greeks and Dardanians. The Dardanians are said to have pushed the Channelled Ware groups back, but finally overrun parts of them in their Eastern territory in particular, and assimilating those, clearly. So they had a strong double substrate Thracian effect. First from early Channelled Ware groups, which infiltrated their core zone, then by assimilating a later Thracian substrate.
