However, ethnographic and historical literatures worldwide have suggested inconclusive functions for similar implements. We conducted a range of experiments under realistic conditions, including hide and plant processing and earth-working, followed by use-wear analysis, to identify the functions of the Hemudu scapular implements. The results suggest that no more than half of the implements were employed as si and that their penetrability and durability were rather limited. These findings help explain why Hemudu should not be labeled as a farming society. Through experimentation and use-wear analysis, we produced relatively large datasets that make a significant contribution to the identification of soil-derived wear patterns on bone tools. We also included quantitative measurements of soil properties to ensure similarities in use contexts between our experimental and archaeological analogies in order to reach reliable functional identifications. Our approaches and results, therefore, provided a solid base for re-evaluating previous research as well as building a standardized database of scientific value for future evaluation and adjustment, even if that future research is done in isolation and in different soil contexts.

Historical records document the use of settlement relocation as a strategy for social engineering in China no later than the late Shang dynasty (1250–1046 B.C.). We employ placemaking theory to examine social changes associated with population movements to Taosi (2300–1900 B.C.) and Erlitou (1750–1520 B.C.) and the processes of urban construction concomitant to the movements at each site. Furthermore, we employ structuration theory to interpret the process of political knowledge building as concerns settlement relocation and social engineering. Based on our assessment of settlement histories, divisions of space, burial patterns, and community formation, we conclude that the use ofsettlement relocation as political strategy was formulated during the Taosi and Erlitou eras, and that it was intentionally implemented for political reform by Phase II of Erlitou.

In the Hemudu Culture (7000–5000 B.P.), bone (scapula) digging tools were used from the earliest times, whereas peoples in surrounding areas used stone spades. A range of experiments on manufacturing costs, durability, and use efficiency under realistic conditions show that bone and stone spades are functionally equivalent when soils are soft, but that stone implements provide significant and easily perceived advantages when working harder soils. The persistence of scapular spades in the Hemudu Culture would have constrained decisions about undertaking large construction projects under normal soil conditions. Our results show that, in addition to generalized labor for construction, labor demands for producing earth-working implements for large-scale prehistoric earthworks could have also been substantial. These findings not only help explain the processes of intensifying rice-agriculture and se...

However, case studies of craft transmission for osseous technology are rare despite their equal importance to pottery and lithic industries in preindustrial societies. Our research fills the gap by examining early Hemudu Culture’s (7000–6000 BP) scapular implements in the southern Yangzi Delta to understand the linkage between learning and maintaining the scapular shovel tradition in Hemudu’s socio-economic context. We first traced the history of scapular tools to the precedent Kuahuqiao Culture (8200–7000 BP), then used published experimental results to identify the product traits pertinent to craft learning and infer Hemudu scapular shovel blades’ learning and production patterns. Hemudu scapular shovels had a unique, complicated hafting style and an evidential raw material preference for old water buffalo scapulae. However, the blades’ morphological details and technical solutions varied significantly. In addition, most finished products display manufacturing mistakes resulting from crafters’ lacking skills, experience, and intervention. Practice pieces are rare compared to finished and used products. Although additional evidence implies that practice might have been more common than the studied sample suggested, it was carried out with less-than-ideal bones and insufficient for developing technical competency. We argue that the Hemudu societal norms for a scapular shovel applied only to the highly visible aspects of the implement. The shaft and ligatures could reduce the visibility of many manufacturing flaws on the shovel blade to reach the desired visual effect of the shovel. The shovel blades were made by household crafters emulating from an artifact or a memorized template but had insufficient training and practice in manufacturing. Communities of practice were minimal to nonexistent among the shovel makers; alternative mechanisms to maintain the technical norms or hold a high product standard were also lacking. Therefore, we concluded that the scapular shovels were less important as a technical implementation than a visual communicator of social identity. The binary system of conformist style and material preference mixed with loose quality control in the shovel blade production reveals that social conformity and the associated learning pattern are circumstantial and fluid even for a community’s iconic implement. Further research with other artifact types in Yangzi Delta would help shed light on whether similar learning patterns were applied besides the creation of scapular shovels.

Quantitative microscopy characterizing the surface texture of wear traces has helped develop a more standardized chipped stone tool microwear practice. However, to date, these surface metrology methods have not been used to characterize ground stone tool surfaces. To expand the range of raw materials and tool types tested with these methods, we explore the application of imaging confocal microscopy for the quantification of an assemblage of experimental hoes, modelled after Late Neolithic and Early Bronze Age artifacts from China. Surface texture properties of sediment wear are compared to wear from wooden hafts to identify whether confocal microscopy can distinguish between different wear types. The results show that there is a significant difference between sediment and hafting wear and suggests further research is needed to identify how experimental conditions affect polish measurements within wear types. This preliminary study indicates that imaging confocal microscopy has excellent potential for the quantification of microwear traces on ground stone tools and may contribute to our understanding of earth working tools in prehistory.

The appearance of microwear on ground stone artefacts is normally more complex and complicated than on chipped stone artefacts, as the mineral and textural components of the raw materials chosen for ground stone artefacts often are more heterogeneous. Currently, the baseline principles for analyzing microwear on ground stone artefacts are primarily based on the studies of non-cutting tools such as grinding and abrading implements. Our research uses experimental ground stone shovels and hoes crafted from oolitic dolomite to understand the raw material's effect on microwear development and to distinguish the microwear patterns associated with varying sediment conditions in the Neolithic and Early Bronze archaeological sites in the Middle Yellow River and Lower Yangzi River in China. The research combines detailed petrographic analysis of the raw material, measurement of the worked material's physical properties, and careful examination of microwear using both high-power and low-power approaches. The results not only advance the methods for microwear analysis on heterogeneous raw materials, but also enrich the microwear dataset for understanding earth-working activities associated with ground stone tools. Applying our results to analysis of archaeological counterparts will add additional lines of evidence to evaluate the importance of farming and construction activities in Neolithic and Bronze Age subsistence systems.

In the early Hemudu culture (7000-6000 BP) in eastern China, bone, particularly wild water buffalo scapulae, was preferred for crafting spades to modify the margins of wetlands for cultivation and occupation. Experimental and ethnographic research show that earth properties in the area adequately explains why wooden spades were less common; however, preference for bone spades over stone spades requires explanations beyond techno-functions during use. This paper identifies potential factors during the manufacturing procedure that might have encouraged the development and persistence of the scapular spade tradition. Replication experiments reconstructed the manufacturing procedure of the Hemudu scapular spade in comparison to that of a groundstone equivalent. The results showed that the manufacture knowledge was sophisticated for bone as well as for stone. However, the adequate level of know-how for successful production was lower for bone. Surprisingly, the costs in time and manufacturing tools for crafting a good enough bone tool were higher than those for a stone counterpart. In fact, the manufacture of bone tools involved the use of advanced groundstone tools. Overall, the Hemudu tool producers appear to have made their technological choices based on traditional conformity as well as resistance to motor skill adjustment rather than comprehensive cost-benefit assessment. The persistence of the scapular spade tradition led to increased investments into sophisticated modifications to cope with increasingly arduous earth-working tasks and likely led to increased investment into raw material procurement when bone raw materials became scarce. The results also suggest that technological ease and manufacturing costs in tool production should be evaluated carefully within the behavioral contexts, while taking into account that implements crafted from a variety of raw materials were employed in manufacturing the tool and that the costs and benefits in production are not equally perceivable to decision makers.

Although the scapula normally would not be considered for distinguishing among adult age classes, the maturity and thickness of the bone were an important consideration for its technological performance. Statistical analysis of the width and rugosity level of the scapular neck show that scapulae from older adult wild buffalo was strongly preferred for crafting earth‐working implements. This raw material was less commonly available to tool makers in comparison with the bones of younger animals. In order to conserve the scapulae of old buffalo for tool production, the Hemudu people likely took these heavy bones from kill sites. They seldom transported scapulae from younger animals; such raw material was rarely used, and presumably only when the desirable material was unavailable. Our approaches for reconstructing buffalo mortality patterns are based on the development of the scapular bone. In addition to water buffalo and cattle, the approach is applicable to other ungulate scapulae that have been transformed into artefacts (tools and oracle bones) in prehistoric and historic cultures. This attempt at testing for age bias in scapular raw material selection can further stimulate methodological development to reveal activities surrounding bone acquisition in preindustrial societies.

In addition to water buffalo and cattle, the approach is applicable to other ungulate scapulae that have been transformed into artefacts (tools and oracle bones) in prehistoric and historic cultures. This attempt at testing for age bias in scapular raw material selection can further stimulate methodological development to reveal activities surrounding bone acquisition in preindustrial societies.

Rammed-earth construction techniques (i.e., tamping or pounding loose earth into a solid mass with a rammer) were invented in the Iron Age Mediterranean and the Neolithic Middle Yellow River Valley and adopted across the globe overtime. Rammed-earth techniques were widely employed for building massive structures ranging from large tombs to the Great Wall in late Neolithic and dynastic China; as such, understanding the labor costs involved is fundamental for understanding labor organization for these public works.
Ethnographic, historic, and previous experimental accounts provide inconsistent labor estimations for rammed-earth compaction. Our research develops a method for contextually relevant and reliable labor estimations for archaeological rammed-earth structures of varying quality. We built a rammed-earth wall under realistic conditions, quantified the influential factors for rammed-earth quality, and developed the protocol for calibrating experimental results to match the archaeological record.
Our calibrated estimations for the rammed-earth walls at the Taosi and Erlitou urban sites reveal rather light labor demands on the inhabitants, implying that monumental architectures at the dawn of China’s dynastic history in the Central Plain were less about manifesting power than facilitating social changes. Our method can be applied to estimate labor costs for earthen structures in general and enables comparative studies across time and space regarding the relations between massive earthen construction and social-political transformation.
Quantitative microscopy characterizing the surface texture of wear traces has helped develop a more standardized chipped stone tool microwear practice. However, to date, these surface metrology methods have not been used to characterize ground stone tool surfaces. To expand the range of raw materials and tool types tested with these methods, we explore the application of imaging confocal microscopy for the quantification of an assemblage of experimental hoes, modelled after Late Neolithic and Early Bronze Age artifacts from China. Surface texture properties of sediment wear are compared to wear from wooden hafts to identify whether confocal microscopy can distinguish between different wear types. The results show that there is a significant difference between sediment and hafting wear and suggests further research is needed to identify how experimental conditions affect polish measurements within wear types. This preliminary study indicates that imaging confocal microscopy has excellent potential for the quantification of microwear traces on ground stone tools and may contribute to our understanding of earth working tools in prehistory.
Ground stone tools encompass a wide array of implements important in the economic organization of many prehistoric and early historic societies; however, functional analysis of ground stone artefacts has been relatively limited in comparison to chipped stone tools. The appearance of microwear on ground stone artefacts is normally
more complex and complicated than on chipped stone artefacts, as the mineral and textural components of the raw materials chosen for ground stone artefacts often are more heterogeneous. Currently, the baseline principles for analyzing microwear on ground stone artefacts are primarily based on the studies of non-cutting tools such as
grinding and abrading implements.
Our research uses experimental ground stone shovels and hoes crafted from oolitic dolomite to understand the
raw material's effect on microwear development and to distinguish the microwear patterns associated with
varying sediment conditions in the Neolithic and Early Bronze archaeological sites in the Middle Yellow River
and Lower Yangzi River in China. The research combines detailed petrographic analysis of the raw material,
measurement of the worked material's physical properties, and careful examination of microwear using both
high-power and low-power approaches. The results not only advance the methods for microwear analysis on
heterogeneous raw materials, but also enrich the microwear dataset for understanding earth-working activities
associated with ground stone tools. Applying our results to analysis of archaeological counterparts will add
additional lines of evidence to evaluate the importance of farming and construction activities in Neolithic and
Bronze Age subsistence systems.
