Not often talked about, but Corded Ware, specifically Balanovo, descended groups invaded the Steppe and replaced the Yamnaya-Continuin Catacombnaya Culture in 2200bc. The Abashevo Culture (1st image) extended across the forest steppe massively and also the Urals, where it later gave rise to Sintashta. In 2200bc, Abashevo groups moved southward to exploit the Climactic Changes that were ravaging the Catacomb Groups. This Abashevo Descended culture is known as Babino AKA Multiroller ceramics. Babino was primarily R-Z93 and genetically a 40~-60~% mix of Catacomb and Abashevo. The second image shows the Babino Culture in its earliest stage.

Babino at its zenith (3rd image) encompassed the Entire Steppe, although it misses areas previously inhabited by Catacomb in the Ciscaucasus. This area was lost to the Lola and Nevinnomysk Cultures, which were genetically distinct from Indo-European groups and most resemble Steppe-Maykop populations.

After 1600bc, the Babino Culture would be pushed out of most of the Steppe by another Culture, which had the same ancestor of Abashevo, the Srubnaya Culture. Babino groups were forced to reorganize into a new culture, the Noua-Sabatinovka-Coslogeni(-radovanu) Complex. The Srubnaya Invasion forced them westward into Transylvania and Mutenia as well as the slopes of the carpathians, destroying the previous Monteoru Culture, which was in deep continuity with the Cernavoda II Culture since 3200bc, and was possibly related to Anatolians such as Luwians and Hittites.

The NSC Complex was later replaced by the Belegis II Channeled ware Complex in 1300bc, contributing almost no ancestry to later groups, thus constituting complete annihilation from the lands west of the Dniester. The Channeled ware complex was possibly Para-Dacothracian, or Dacothracian directly. In 1000bc Dacothracians Proper of the Stamped Ware horizon would move in from the south to replace Channeled ware
