A study by Yinqiu Cui et al. from 2013 found that 63% of the combined samples from various Hongshan archeological sites belonged to the subclade N1 of the paternal haplogroup N-M231 and calculated N to have been the predominant haplogroup in the region in the Neolithic period at 89%, its share gradually declining over time. Today this haplogroup is most common in Finland, the Baltic states and among northern Siberian ethnicities, such as the Yakuts. Other paternal haplogroups identified in the study were C and O2a, both of which predominate among the present-day inhabitants. Nelson et al. 2020 link proto-Turkic languages and the proto-Turkic people to the Hongshan culture in a wider neolithic “Transeurasian” context.
Artifacts
Hongshan burial artifacts include some of the earliest known examples of jade working. The Hongshan culture is known for its jade pig dragons and embryo dragons. Clay figurines, including figurines of pregnant women, are also found throughout Hongshan sites. Small copper rings were also excavated.
Religion
The archaeological site at Niuheliang is a unique ritual complex associated with the Hongshan culture. Excavators have discovered an underground temple complex—which included an altar—and also cairns in Niuheliang. The temple was constructed of stone platforms, with painted walls. Archaeologists have given it the name Goddess Temple due to the discovery of a clay female head with jade inlaid eyes. It was an underground structure, 1m deep. Included on its walls are mural paintings. Housed inside the Goddess Temple are clay figurines as large as three times the size of real-life humans. The exceedingly large figurines are possibly deities, but for a religion not reflective in any other Chinese culture. The existence of complex trading networks and monumental architecture point to the existence of a "chiefdom" in these prehistoric communities. Painted pottery was also discovered within the temple. Over 60 nearby tombs have been unearthed, all constructed of stone and covered by stone mounds, frequently including jade artifacts. Cairns were discovered atop two nearby two hills, with either round or square stepped tombs, made of piled limestone. Entombed inside were sculptures of dragons and tortoises. It has been suggested that religious sacrifice might have been performed within the Hongshan culture.
Feng shui
Just as suggested by evidence found at early Yangshao culture sites, Hongshan culture sites also provide the earliest evidence for feng shui. The presence of both round and square shapes at Hongshan culture ceremonial centers suggests an early presence of the gaitian cosmography. Early feng shui relied on astronomy to find correlations between humans and the universe.
Some Chinese archaeologists such as Guo Da-shun see the Hongshan culture as an important stage of early Chinese civilization. Whatever the linguistic affinity of the ancient denizens, Hongshan culture is believed to have exerted an influence on the development of early Chinese civilization. The culture also have contributed to the development of settlements in ancient Korea.
