Proto-Transeurasian originated 9181 years ago in West Liao River basin. Dispersal driven by Early Neolithic millet farming, not pastoralism. Amur hunter-gatherer ancestry core to all Transeurasian speakers. West Liao Neolithic farmers mixed Amur and Yellow River genes. Millet spread east to Korea and Primorye by 5500 bp with Koreanic and Tungusic languages. Bronze Age rice farmers from Liaodong replaced Jomon-admixed Koreans. Massive Korean migration to Japan brought Upper Xiajiadian ancestry and Japonic language. Jomon ancestry present in Neolithic Korea up to 95% but vanished over time. Yayoi Japanese genomes show Jomon plus Korean Bronze Age ancestry. Nagabaka Ryukyuans derived from northern Jomon, not Taiwan. Amur ancestry traces to Japanese and Korean speakers today. Pastoralist hypothesis for Transeurasian origins refuted by linguistics, archaeology, genetics. Neolithic vocabulary shows millet, pigs, dogs, no cattle or horses. Bronze Age branches borrowed rice, dairy, horse terms from contacts. Population growth followed millet farming before Late Neolithic crash. Two millet centers birthed Sino-Tibetan on Yellow River, Transeurasian on West Liao. Jomon culture and genes stretched to southern Ryukyus and Korean coast.
