↑ Skulls from Potapovka burials belong to the massive proto-Europoid type and are similar to the earlier Catacomb and genetically follow the Timber-grave and west Andronovo, but differ from Abashevo.[19]
↑ "[M]assive broad-faced proto-Europoid type is a trait of post-Mariupol’ cultures, Sredniy Stog, as well as the Pit-grave culture of the Dnieper’s left bank, the Donets, and Don... During the period of the Timber-grave culture the population of the Ukraine was represented by the medium type between the dolichocephalous narrow-faced population of the Multi-roller Ware culture (Babino) and the more massive broad-faced population of the Timber-grave culture of the Volga region... The anthropological data confirm the existence of an impetus from the Volga region to the Ukraine in the formation of the Timber-grave culture. During the Belozerka stage the dolichocranial narrow-faced type became the prevalent one. A close affinity among the skulls of the Timber-grave, Belozerka, and Scythian cultures of the Pontic steppes, on the one hand, and of the same cultures of the forest-steppe region, on the other, has been shown... This proves the genetical continuity between the Iranian-speeking Scythian population and the previous Timber-grave culture population in the Ukraine... The heir of the Neolithic Dnieper-Donets and Sredniy Stog cultures was the Pit-grave culture. Its population possessed distinct Europoid features, was tall, with massive skulls... The tribes of the Abashevo culture appear in the forest-steppe zone, almost simultaneously with the Poltavka culture. The Abashevans are marked by dolichocephaly and narrow faces. This population had its roots in the Balanovo and Fatyanovo cultures on the Middle Volga, and in Central Europe... [T]he early Timber-grave culture (the Potapovka) population was the result of the mixing of different components. One type was massive, and its predecessor was the Pit-grave-Poltavka type. The second type was a dolichocephalous Europoid type genetically related to the Sintashta population... One more participant of the ethno-cultural processes in the steppes was that of the tribes of the Pokrovskiy type. They were dolichocephalous narrow-faced Europoids akin to the Abashevans and different from the Potapovkans... The majority of Timber-grave culture skulls are dolichocranic with middle-broad faces. They evidence the significant role of Pit-grave and Poltavka components in the Timber-grave culture population... One may assume a genetic connection between the populations of the Timber-grave culture of the Urals region and the Alakul’ culture of the Urals and West Kazakhstan belonging to a dolichocephalous narrow-face type with the population of the Sintashta culture... [T]he western part of the Andronovo culture population belongs to the dolichocranic type akin to that of the Timber-grave culture.[20]
↑ "Morphological data suggests that both Fedorovka and Alakul’ skeletons may be related to Sintashta groups, which in turn may reflect admixture of Neolithic forest HGs and steppe pastoralists, descendants of the Catacomb and Poltavka cultures."[18]
