The test result of haplogroup [R1a in a Northwest Russian Karelian released this week] confirmed for me the probability that ceramic technology entered the West as a result of a population movement in the early Holocene.
|Trek of Ceramic Technology, From Asia to the West (Jordan & Zvelebil, 2014)|
In time it may be shown that the transmission of ceramic pottery technology to the West came as the result of a population movement of R1 lineages creeping from the Altai into the Urals and the Southern Caspian where the technology appears simultaneously.
Similarly, the transmission of [ceramic technology into the New World] probably comes from the Yenisei region in a somewhat later movement of R1's brother haplogroup Q's subclades moving in the opposite direction, both descended from P-M45.
Quickly, here's a some comments regarding ceramic's Central Asian trek by Jordan & Zvelebil:
"After c. 7,500 BC (9,500 BP), in the context of early post-glacial environmental conditions, pottery is dispersed further to the north-west, via the northerly route through central Russia, the Upper Volga, into Karelia and beyond, forming various local traditions of pointed-based pitted and combed ware, such as the Sperrings pottery of Finland, and entering the East Baltic and northern Scandinavia by about 5,000 BC"
"More tentatively, it is possible that as a part of this general process of ceramic dispersal, the production of pottery also spreads via a more southerly route from Central Asia along the eastern shore of the Caspian south, into northwest Iran and northern Syria."Also from the Haak paper was the presence of R1b among an early Cardial farmer in Northern Iberia. This certainly shows that early R1b was in contact with either Byblian or Thessalonian farmers in the final days of the Pre-Pottery Neolithic B. We know that the end of the PPNB saw sweeping changes from pottery cultures of Eastern Anatolia and further East.

A couple of footnotes:
* We should be careful not to get wrapped around the axle of periodization and technological classification. The Karelian and Samaran are referred to as belonging to the "Mesolithic" or "Neolithic" or "Hunter-Gatherer", none of which is equivalent those of Western Europe in terms of technology or age. Within a certain context they have meaning, otherwise they are confusing or misleading. I would focus on calendar dates and understand the changes taking place in these regions that are being settled by a continuous stream of peoples from the Southeast.
