Jiahu () was the site of a Neolithic settlement based in the central plain of ancient China, near the Yellow River. It is located between the floodplains of the Ni River to the north, and the Sha River to the south, north of the modern city of Wuyang, Henan Province. Most archaeologists consider the site to be one of the earliest examples of the Peiligang culture. Settled around 7000 BC, the site was later flooded and abandoned around 5700 BC. The settlement was surrounded by a moat and covered a relatively large area of 55,000 square meters (5.5 hectare). At one time, it was "a complex, highly organized Chinese Neolithic society", home to at least 250 people and perhaps as many as 800.
The important discoveries of the Jiahu archaeological site include the Jiahu symbols, possibly an early example of proto-writing, carved into tortoise shells and bones; the thirty-three Jiahu flutes carved from the wing bones of cranes, believed to be among the oldest playable musical instruments in the world; and evidence of alcohol fermented from rice, honey and hawthorn leaves.
A broad variety of other artifacts indicates a fairly advanced settlement for the early Neolithic period, including residences, burial sites, pottery kilns, an assortment of implements made of stone and earthenware, and a large central structure believed to be a communal workspace. To date, 45 residences have been excavated at Jiahu. Most of these are small, between four and ten meters. Most of these were semi-subterranean (partially dug into the earth) and with a single room; however, some of these had additional rooms built on later. Rubbish pits and storage cellars were also excavated, and nine pottery kilns were identified.
Discovery and excavation of the site
Discovered by Zhu Zhi in 1962, extensive excavation of the site did not occur until the 1980s. Most of the site still has not been excavated, although work is slowly progressing. The excavation of Jiahu burial sites and rubbish pits has been productive, yielding abundant evidence about the lives of the Jiahu people. Chinese researchers from the Henan Provincial Institute of Cultural Relics and Archaeology, led for many years by Zhang Juzhong, a professor from the University of Science and Technology of China, have carried out archaeological research around the site for decades.
Zhang's team conducted excavation of portions of the site in seven stages; each stage took two to three years. A large portion of the Jiahu site was excavated in the first two phases of the project, between 1983 and 1987. Zhang and his assistants published the findings of the first two phases in detail in the journal Antiquity.
Jiahu and Peiligang
Some archaeologists point to cultural distinctions between Jiahu and Peiligang, as well as the distance: Jiahu is isolated, many kilometers south of the larger Peiligang grouping of over 100 archaeological sites in a fairly compact area. The distance would have represented a journey on foot of several days in the Neolithic era. This school of thought suggests that Jiahu and Peiligang represented separate, neighboring cultures that interacted and shared many characteristics. Other early Neolithic settlements in this part of the world were much farther south and east.
Archaeologists have divided Jiahu into three distinct phases. The oldest phase ranges from 7000 to 6600 BC; the middle phase ranges from 6600 to 6200 BC; and the last phase ranges from 6200 to 5700 BC. The last two phases correspond to the Peiligang culture, while the earliest phase is unique to Jiahu.
Careful examination of the skeletons of over 400 individuals, removed from more than 300 graves, by several scientific teams over the course of the past 30 years illustrates that the Jiahu ethnic group was a part of the Northern Mongoloid group, and identified closely with the Miaodigou and Xiawanggang sub-groups which were also descendants of hunting and gathering tribes in Henan Province, and the Dawenkou, Xixiahou and Yedian sub-groups that were later found in Shandong Province.
