Disintegrating habitats also affect local Indigenous communities, whose deep-rooted histories include stewardship of these biologically and culturally essential places. Understanding human-fisheries dynamics is crucial for biocultural restoration. We present a snapshot of fisheries use at <em>Digawututklh</em> (CA-HUM-23), a Late Holocene ethnographic Wiyot village on the north spit of <em>Wigi</em> (Humboldt Bay), an area experiencing the highest rate of level rise in California that it is exacerbated by the high rate of subsidence where the Juan de Fuca Plate dives under the North American Plate. To expand knowledge of species use, we employ complementary faunal and genetic analyses and test the capabilities of ancient DNA (aDNA) barcoding methods. We employ a broad-spectrum sampling approach to identify previously unidentifiable elements and confirm aDNA identification of fish bone is feasible on a wide range of non-vertebral elements and tiny, fragile fragments. Our findings highlight the potential of this methodology and the need for further sequencing of modern fish bones to refine aDNA species identification. This biodiversity-centered approach provides a more comprehensive picture of historical fisheries in this endangered northern California estuary. Contrary to a salmon-focal economy assumed in prominent developmental models, results reveal complex interactions with multiple fish species, employing diverse capture methods and technologies, such as tidal weirs, nets, and spears. Identified fish species, along with shellfish, crab, waterfowl, and mammals recovered at the site, indicate significant record of human connectivity with eelgrass (<em>Zostera marina</em>) meadows. The eelgrass biome of Humboldt Bay —a highly productive habitat that supplies nutrients, shelter, and nursery grounds for diverse species—was a key target for early indigenous aquaculture, practiced by the some of the earliest sedentary plank house villagers in coastal northwest California. The study provides insight into Wiyot sustainable practices, informed by traditional ecological knowledge of food webs and seasonal spawning and migratory patterns.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"181 ","pages":"Article 106267"},"PeriodicalIF":2.6,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144595469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previously, the ELISA method was successfully used in the identification of the glue in family level. However, the method can not tell the species of the glue. For example, it can not known whether the glue was from cattle or sheep using ELISA methods. This study provides a novel biological technique to identify the species of animal glue used as ancient binders. Hence, the accurate identification results at the species level can be obtained by DNA barcoding method with low detection limits. Moreover, ten animal glues belong to different species can be identified using a pair of universal primer at one time.

It was demonstrated that certain animals were not only consumed as food resource at that time, but their leftover bones, skins, and other parts were also utilized to produce animal glue. Additionally, our findings is consistent with the records in ancient books, which documented the species of animals frequently used in the manufacturing of animal glue.

This study investigated whether the stone reduction behaviors of apes fall within the range of experienced modern humans. The actions of two bonobos while engaged in stone toolmaking were coded by two raters and compared to five experienced human knappers using a correspondence analysis. We found that actions associated with bonobo-made tools cluster together and are distinct from those used by modern humans to make choppers, chopping-tools, and handaxes. However, when handaxe toolmaking actions are excluded, greater overlap in action patterns emerges. The most discriminating behaviors associated with the bonobo-made tools include holding the hammerstone in their left hand and above the shoulder before striking, supporting the core on both the hand and foot or on the ground, a secant angle of percussion, and an impact location deep beyond the edge of the core. Additionally, the bonobos’ tools are associated with negative percussion results (e.g., a strike that fails to produce a flake).
