Ancient DNA reveals the population interactions and a Neolithic patrilineal community in Northern Yangtze Region

Abstract

The scarcity of ancient genomes of early rice cultivators has hindered our understanding of their genetic profiles and dynamic interactions with millet cultivators. In this study, we analyzed 58 ancient genomes from Baligang, a long-term settlement situated on the northern rim of the Middle Yangtze River Basin, spanning from the Middle Neolithic to the Late Bronze Age. This chronostratified genetic dataset offers comprehensive genomic insights into populations engaged in early rice cultivation, enhancing our understanding of East Asian demographic history. Our study revealed that Baligang experienced successive waves of admixture over time, with ~4,200 BP as a critical transition point, marked by a significant genomic influx of southern East Asian populations. We also identify the detailed kinship relations within multi-generational secondary burial and the existence of patrilineal communities dating back five millennia, offering fresh perspectives on early social structure in prehistoric China.
