Archaeologists commonly divide the culture into three phases: the early phase (4100-3500 BC), the middle phase (3500-3000 BC) and the late phase (3000-2600 BC). Based on the evidence from grave goods, the early phase was highly egalitarian. The phase is typified by the presence of individually designed, long-stemmed cups (gu). Graves built with earthen ledges became increasingly common during the latter parts of the early phase. During the middle phase, grave goods began to emphasize quantity over diversity. During the late phase, wooden coffins began to appear in Dawenkou burials. The culture became increasingly stratified, as some graves contained no grave goods while others contained a large quantity of grave goods.
The type site at Dawenkou, located in Tai'an, Shandong, was excavated in 1959, 1974 and 1978. Only the middle layer at Dawenkou is associated with the Dawenkou culture, as the earliest layer corresponds to the Beixin culture and the latest layer corresponds to the early Shandong variant of the Longshan culture. The physical similarity of the Jiahu people to the later Dawenkou (2600 BC±4300 BC) indicates that the Dawenkou might have descended from the Jiahu, following a slow migration along the middle and lower reaches of the Huai river and the Hanshui valley.
