ABSTRACT This paper is a reply to Chatters et al. (2021. “Evaluating Claims of Early Human Occupation at Chiquihuite Cave, Mexico.” PaleoAmerica 8, doi:10.1080/20555563.2021.1940441), in which they raise a large number of doubts about the legitimacy of our claims of earlier-than-expected human presence at Chiquihuite Cave, in northern Zacatecas, Mexico, mainly questioning the artificial nature of the lithic assemblage and the integrity of our geological contexts. We respond to their main topics of concern, contributing arguments in defense of the human origin of the artifacts. We also include 10 examples of stone tools, with full descriptions and photographs, focusing on modified flakes that bear indicators of use-wear and intentional modification.

ABSTRACT This is a response to a critique, “Current Understanding of the Earliest Human Occupations in the Americas: Evaluation of Becerra–Valdivia and Higham (2020)”, made by Potter et al. (2021) on one of our previous publications (“The timing and effect of the earliest human arrivals in North America”; Becerra–Valdivia and Higham, 2020, Nature). Here, we address their concerns and clarify their misunderstandings.

ABSTRACT Since 2009, systematic interdisciplinary investigations on the Alpena-Amberley Ridge in Lake Huron have documented hunting features, stone tools and debitage, and unique paleoenvironmental data reported in numerous peer-reviewed publications. Andrew A. White presents a contrarian critique of this work that attempts to dismiss each find and hypothesis that has been generated by the research. White’s assertions rely on a cherry-picked reading of the literature, outdated typological analogies and paleoenvironmental models, and are rife with contradictions. Yet White is unable to present a convincing or coherent counter-scenario to account for the Lake Huron data. This critique aptly illustrates that there is still much research to be done in the Great Lakes.
自2009年以来，对休伦湖Alpena-Amberley山脊进行了系统的跨学科调查，记录了狩猎特征、石器工具和碎屑，以及许多同行评审出版物中报道的独特的古环境数据。安德鲁·a·怀特(Andrew a . White)对这项工作提出了一种相反的批评，试图驳斥这项研究产生的每一个发现和假设。怀特的断言依赖于对文献的精心挑选，过时的类型学类比和古环境模型，并且充满了矛盾。然而，怀特无法提出一个令人信服或连贯的反方案来解释休伦湖的数据。这一批评恰如其分地说明，在五大湖地区仍有许多研究有待完成。

ABSTRACT A widely accepted model for the peopling of the Americas postulates a source population in the Northeast Asian maritime region, which includes northern Japan. The model is based on similarities in stone artifacts (stemmed points) found in North American sites dating as early as 15,000 years ago and those of comparable age in Japan and neighboring regions of Northeast Asia. Here we show, on the basis of data and analyses in biological anthropology, that the people who made stemmed points in northern Japan (labeled “Incipient Jomon” in the archaeological literature) represent an unlikely source population for the indigenous peoples of the Western Hemisphere.

ABSTRACT A series of papers has developed the claim that stone features on the submerged Alpena-Amberley Ridge (AAR) in Lake Huron provides unique insight into the Paleoindian caribou-hunting economies of the Great Lakes. The documented human occupation of the AAR dates to the late Early Holocene (about 9000 calendar years ago): however, a time when glacial ice was far to the north and the region was occupied by hunting-gathering societies with ties to the western Great Plains and the deciduous forests of the Eastern Woodlands. Key elements of the caribou-hunting scenario as presented are poorly explained, contradictory, and/or ecologically unsound. Ethnographic and archaeological data demonstrate the use of structures for hunting other kinds of large game, presenting possibilities for alternative explanations. Constructing a satisfying explanation of the AAR features will require expanding the scope of investigation to develop and test multiple hypotheses that engage with the terrestrial archaeological record.

ABSTRACT Cave and rockshelter sites have long been the cornerstone of Western Stemmed Tradition (WST) research in the northwestern Great Basin; however, these sites likely offer a narrow view of Terminal Pleistocene and Early Holocene lifeways. Open-air sites dominate the WST record and are critical to our understanding of WST settlement–subsistence practices and technological organization. I present the results of a lithic technological, source provenance, and spatial analysis of the Catnip Creek Delta (CCD) Locality, Guano Valley, OR. The CCD Locality contains one of the densest concentrations of Paleoindian artifacts in the region. My results indicate that the CCD Locality WST assemblage is likely a product of numerous short-term occupations by residentially mobile groups who primarily used the location to replenish their lithic toolkit and as a hunting location.

ABSTRACT Over the past few decades several genetic models have been published to explain the peopling of the Americas. Most of these models have not been fully reconciled with prior ones and with local and regional archaeological records. The implications of this and other concerns are discussed and solutions offered to better coordinate the joint approach of the two disciplines in the study of First Peoples and in archaeology and genetics in general.

ABSTRACT A chert object embedded in the cranium of a bison found at the Alexon site, Florida, is cited as direct evidence of human and megafauna interaction at the end of the Pleistocene in the American Southeast. Previous analyses identified the chert object as the mid-section of a lanceolate projectile point. Radiocarbon ages on unpurified bison collagen from two separate bison elements yielded Late Pleistocene and Early Holocene ages. We were able to relocate the site and examine the stratigraphy, but our attempts to radiocarbon date the bone failed. We obtained micro-computed tomography scans and used digital imaging software to generate a three-dimensional rendering of the embedded object. Finally, the skull and embedded object were visually examined. We conclude that the object embedded in the skull is not an artifact and that the Alexon site is a paleontological locality.

ABSTRACT Triangular non-stemmed points (TNSPs) have been recovered for several decades from early archaeological sites in different regions of South America. We report a synthesis and review of 63 early Holocene radiocarbon dates (∼12,650–8050 cal yr BP) of the main sites where TNSPs have been recovered and records of this point design with fluting technology. The oldest ages of dated sites with TNSPs are synchronous with ages obtained for Fishtail point sites. The extra-regional evidence allows discussion of aspects related to the use of open environments, chronology, size, context, fluting technology and distribution of these points, leading to the generation of new ways to continue increasing our understanding of cultural complexity in early settlement in South America. The results open new perspectives and implications for the debate on social interaction and technological transmission by Paleoamericans during the peopling of South America.

ABSTRACT Archaeological research of late Pleistocene sites in northeastern Brazil has rarely analyzed site formation processes from a geoarchaeological perspective. This has contributed to the long-held debate over the reliability of Pleistocene ages and the anthropic origin of stone tools and combustion features. In this work, we combine high-resolution geoarchaeological methods to study the formation processes of the Toca da Janela da Barra do Antonião North site (TJBA-North), located in a surface karst about 12 km northeast of the classical site of Boqueirão da Pedra Furada (Serra da Capivara, Piauí). The site contains stone tools and megafauna remains in sedimentary levels that have been dated by optically stimulated luminescence (OSL) as more than 20,000 years ago up to the early Holocene. Using micromorphology, Fourier transform infrared spectrometry (FTIR), micro-FTIR on the micromorphology thin sections, and magnetic analyses, we carried out a comprehensive study of the climatic conditions during the late and terminal Pleistocene and investigated the depositional history of the site.
巴西东北部晚更新世遗址的考古研究很少从地质考古学的角度分析遗址的形成过程。这促成了长期以来关于更新世时代的可靠性以及石器和燃烧特征的人为起源的争论。在这项工作中，我们结合高分辨率地质考古方法研究了Toca da Janela da Barra do antonio North遗址(TJBA-North)的形成过程，该遗址位于boqueir o da Pedra Furada (Serra da Capivara, Piauí)经典遗址东北约12公里处的表面喀斯特。该遗址包含石器和沉积层的巨型动物遗骸，通过光学刺激发光(OSL)可以确定其年代为2万多年前到全新世早期。利用显微形貌、傅里叶变换红外光谱(FTIR)、显微形貌薄片微傅里叶变换红外光谱(FTIR)和磁学分析等方法，对该遗址更新世晚期和晚期的气候条件进行了全面研究，并对其沉积历史进行了研究。
