The suggestion that the Corded Ware of 3rd millennium BC Europe is derived from earlier cord marked pottery in East Asia is intriguing. The world's earliest pottery was found in southern China, including cord marked pottery from about 13,000 BC. Jomon cord marked pottery dates from about 11,000 BC and Jomon aDNA shows affinity with the aboriginal Taiwanese, suggesting a coastal migration of people and pots from southern China to Japan, and further on to eastern Siberia (the Amur basin and Baikalia).
The earliest pottery in Taiwan, associated with proto-Austronesian speakers, was also cord marked. By about 1000 BC Austronesian speakers from Taiwan had spread Lapita pottery as far as Western Polynesia (Tonga and Samoa).
Pottery was invented independently more than once (in the Americas and West Asia for instance), but perhaps the idea of decorating pottery with cord marks was invented only once and the idea and the practice spread from the Pacific to the North Sea over several millennia.
