Archaeogenetic data shows that "the West Liao River Valley was a contact zone between northern steppe tribes and the Central Plain farming population.
The formation and development of the Lower Xiajiadian Culture population was likely a complex process affected by admixture of ethnically different people".
[5] The Lower Xiajiadian culture remains displayed high genetic affinity to "Yellow River farmers" but were not identical to them, in contrast, the Upper Xiajiadian remains displayed high genetic affinity to Ancient Northeast Asian Amur hunter-gatherers and later Xianbei.
[6] Archaeological and DNA evidence supports examples that the people of the Lower Xiajiadian Culture immigrating to the south and contributed to the gene pool of the Central Plain population during the Bronze Age.
The most commonly found copper and bronze artefacts are dagger-axes with an integrated handle, mace head, piers, knives, and earrings.
Along with professors Gan Zhi-geng and Guo Da-shun, they believe that Lower Xiajiadian contributed to some of the origins of both Shang and Yan cultures.
