In this paper, I examine both approaches and conclude that neither, as currently envisioned, is likely to provide the answers archaeologists seek. Technological complexity is always a work in progress, and deciding where to place the boundary between \"pre-modern\" and \"modern\" is arbitrary. The symbolic approach is better suited to the task but problematic nonetheless, because archaeologists focus only on objects or practices that had no evident utilitarian function. That assumption flies in the face of ethnographic reality. Traditional Indigenous peoples see symbolic meanings in almost everything in their world, whether utilitarian or not, mundane or special, animate or inanimate, natural or supernatural. The hearth, smoke, cardinal directions, colors, plants, animals, water, wind, clouds, rain, thunder, lightning, minerals, even toolstone, all are viewed as sentient, volitional spirit-beings with human-like temperaments, needs, and expectations. Importantly, this worldview introduces spiritually motivated behaviors and constraints that have real world causal agency. Why should we assume that the first time a few peoples scattered across Eurasia or Africa decided to wear ornaments or paint cave walls conveniently coincided with the first time human beings possessed the cognitive capacity for symbolic behavior? A deeply spiritual worldview could have emerged millennia earlier, but saw its expression in other domains of material culture or phenomena, including those that archaeologists routinely dismiss as utterly mundane and utilitarian. I suggest that technological complexity cannot resolve the modernity issue, and that the current focus on symbolism expressed exclusively in non-utilitarian objects and practices is far too narrow and fails to recognize the pervasive nature of spiritualism in traditional societies. I offer what I believe is a more anthropologically sound research paradigm for exploring the origins of modern human behavior, and some admittedly very preliminary suggestions for a way forward.</div></div>","PeriodicalId":101053,"journal":{"name":"Quaternary Environments and Humans","volume":"4 1","pages":"Article 100102"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147398370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using an updated database of Japanese Upper Paleolithic functional studies, this paper conducts a meta-analysis of functional estimates from use-wear traces to examine the differences in stone tool use among three lithic industries in the northeastern Paleo-Honshu Island: Trapezoid (early Upper Paleolithic: EUP, c. 38–32 cal ka BP), Blade point (middle Upper Paleolithic: MUP, c. 32–23 cal ka BP), and Microblade (late Upper Paleolithic: LUP, c. 18–16 cal ka BP) and to discuss how Paleolithic hunter-gatherers organized and adapted their tool use strategies during Marine Isotope Stages 3 and 2. Results suggest that EUP, MUP, and LUP populations organized their stone tool uses differently. The EUP foragers used trapezoidal tools multifunctionally, though infrequently for shaping non-lithic and/or complex tools. In contrast, LUP foragers honed technologies to maintain diverse stone toolkits specialized for processing non-lithic and complex tools. MUP foragers possessed blade tools with a moderate frequency of toolmaking traces and moderate multifunctionality. Taken together, observed diversity of stone tool use likely reflect differences in the toolkit structures that Upper Paleolithic hunter-gatherers designed to adapt to the Late Pleistocene environments on the northeastern Paleo-Honshu Island.</div></div>","PeriodicalId":101053,"journal":{"name":"Quaternary Environments and Humans","volume":"3 4","pages":"Article 100084"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145322453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to Vansina’s view of the region as a terminus for the settlement of diverse Bantu speech communities, the area was likely an important center of diversification and expansion for early Bantu speakers. Under a drier climate favoring the increase of grassland and open woodland around Idiofa but not a general loss of the forest cover, Bantu speakers most probably started occupying the region from the 4th century BCE onwards. Pottery-producing settlements first emerge along the Kwilu River, i.e., at Luani (371–148 BCE) and Lukombe (357–27 BCE), and then near Idiofa (146–18 BCE), where the earliest evidence for iron metallurgy marks the actual start of the Early Iron Age (146 BCE-750CE) south of the Congo rainforest. The first settlers lived in small and enclaved communities without much mutual communication. These were perfect conditions for early divergence within the Bantu language family’s major West-Coastal Bantu branch. While modern language data situate the West-Coastal Bantu homeland between the Kasai and Kamtsha Rivers, this zone was only settled towards the beginning of the common era based on the currently available archaeological data. This apparent mismatch between archaeology and historical linguistics might be due to subsequent processes of language death and population relocation and restructuring. Confirming Vansina’s idea that modern-day Kwilu-Kasai communities do not directly descend from the region’s earliest Bantu-speaking settlers, significant population reshuffling did indeed occur after the Early Iron Age. During the so-called ‘hiatus period’ (750–1450 CE), human activity contracted to a few refuge areas, especially near the modern towns of Bandundu and Idiofa, and the vegetation underwent an irreversible climate-induced shift to open habitats, possibly connected to the Medieval Climate Anomaly. During the Late Iron Age, the study area was rapidly resettled, first in the south (15–16th c. CE), and then in the north (17–18th c. CE), and large cross-regional exchange networks developed. In line with oral histories still existing among Kwilu-Kasai peoples today and with the clans and political and social institutions they share, the region underwent a very advanced demographic, linguistic and cultural integration in the four to five centuries preceding the start of European colonization, which may have involved populations no longer present there today, such as Ubangi-speaking groups.</div></div>","PeriodicalId":101053,"journal":{"name":"Quaternary Environments and Humans","volume":"3 4","pages":"Article 100088"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145322452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
