A puzzling similarity has been observed in some of the ceramics and figurines in several cultures in Eastern Europe (the Trypillia-Cucuteni culture, 6500 - 5500 years before present [ybp]), Thailand (the Ban-Chiang culture, between 7400 and 3800 ybp), China (the Yangshao culture, between 8000 and 4000 ybp), North America (the Anasazi-Mogollon culture, between 7500 ybp and present time). It is remarkable that the ceramics of these four cultures match each other in 17 (45%) of the 38 indicators used to distinguish archeological ceramic piece in the comparative research. Remarkably, all four cultures with look-alike ceramics also use the swastika as a common symbol. We advance the hypothesis that all four cultures are connected by the Aryan (bearers of R1a) migrations between 5500 and 3000 ybp. While the Aryan migrations in Eurasia are well verified by DNA data, those in theAmericasare not known as yet. Consideration of R1ahaplotypes among Native Americans do not conflict with the hypothesis.
