Group 3: Clothing and Survival Strategies - Research from the Water Cave site in Ningxia has provided indirect evidence of clothing production among Paleolithic humans, with small bone tools found that were likely used for processing animal hides [11][13]. - The study indicates that these tools were part of a sophisticated strategy for preparing for winter, highlighting the resourcefulness of ancient populations in adapting to their environment [13]. - The findings suggest that these early humans had developed specialized tools and strategies for resource management, which were crucial for their survival and adaptation [13].

Core Viewpoint - A joint archaeological team has discovered 30 new Paleolithic sites in the Nanhou River basin, with at least 8 sites showing original stratigraphy, indicating significant findings for prehistoric cultural studies in southern China and Southeast Asia [1][3][7]. Group 1: Discovery and Findings - The investigation focused on the Nanhou River site, with the main site designated as BN1 and others numbered from BN2 to BN30 based on their discovery order [3]. - A total of 1,191 stone artifacts were collected during the survey, primarily from the first and second terraces along the river's meandering bends, with some found at higher terraces [3]. - The raw materials for the stone artifacts varied, including sandstone, tuff, mudstone, limestone, conglomerate, sedimentary rock, gneiss, quartzite, and quartz, with sandstone and limestone being predominant [3][5]. Group 2: Cultural Significance - The stone artifacts exhibit characteristics typical of southern China's pebble industry while also reflecting features of the Peace Culture, which represents a transitional phase from hunter-gatherer societies to settled communities in Southeast Asia [5]. - The cultural profile of the artifacts from the surveyed sites aligns with those from the BN1 excavation, with known dating extending back to 14,000 years ago, marking it as the largest and most culturally rich Paleolithic site group discovered in Hainan [7]. - Some surveyed locations still retain original stratigraphy, providing a crucial foundation for future systematic archaeological excavations and research in the region, which could shed light on cultural interactions between southern China and Southeast Asia [7].

Core Findings - The research team at the Gantangqing site published a significant archaeological discovery in the journal "Science," revealing 35 well-preserved wooden artifacts dating back approximately 300,000 years, along with associated cultural relics including stone tools, bone and antler artifacts, animal fossils, plant remains, and evidence of fire [1][2]. Archaeological Significance - The wooden artifacts are the earliest known in East Asia, primarily used for digging edible plant roots, termed "digging sticks." The site also yielded small scrapers that reflect the distinctive characteristics of East Asian Paleolithic culture [1][2]. - The discovery fills a gap in the study of wooden artifacts from the Paleolithic era in China and has significant implications for understanding the origins, processing techniques, functions, and evolutionary development of wooden tools [2]. Cultural Insights - The findings challenge the long-held "East Asian bamboo and wood tool hypothesis," which suggested that ancient humans in East Asia primarily relied on bamboo and wood tools, with simple stone tools serving mainly to create these wooden implements. The evidence from Gantangqing supports the notion that early humans indeed manufactured and utilized wooden tools [2]. - The stone tools found at the site, while traditional in form, contain new information that can reshape the understanding of East Asian Paleolithic cultural traditions and the technological capabilities of ancient humans [3]. Technological Advancements - The stone tools, mostly small and simple in appearance, were previously thought to indicate a lack of technological sophistication. However, some specimens show fine repair marks, indicating a level of detailed craftsmanship. The discovery of soft hammer materials, the earliest known in East Asia, suggests that the region's early inhabitants were not technologically inferior to their Western counterparts [5]. - The characteristics of the stone tools reflect the constraints imposed by the availability of quality raw materials, leading to refined processing techniques and the development of wooden materials, indicating a different evolutionary path compared to Western prehistoric populations [5]. Dietary Insights - The Gantangqing site provides rare evidence of plant-based food resources utilized by early humans, including a variety of nuts and fruits, revealing a broad spectrum of plant materials in their diet. This highlights the unique resource utilization strategies of Southeast Asian ancient populations living in tropical and subtropical environments [6]. - The research underscores the diversity of survival strategies among Paleolithic humans, with East Asian populations relying significantly on plant resources, contrasting with the hunting of large mammals that dominated in temperate regions like Europe [6].

Core Viewpoint - The discovery of 35 well-preserved wooden tools at the Gantangqing site in Yunnan, China, dating back approximately 300,000 years, indicates that wooden tools played a significant role in the survival and adaptation of early humans in East Asia during the Middle Pleistocene [2][8]. Group 1: Discovery and Significance - The Gantangqing site is the first Middle Pleistocene open-air site discovered in Yuxi, Yunnan, providing valuable materials for comparative studies of early Paleolithic culture in China [4]. - The wooden tools found at the site fill a gap in the study of wooden artifacts from the Paleolithic era in China, highlighting their importance in early human culture [4][12]. Group 2: Tool Characteristics and Usage - The 35 wooden tools include digging sticks and small handheld pointed tools, showcasing a complexity that contrasts with the seemingly "primitive" stone tool assemblages of early East Asian Paleolithic [6][7]. - Evidence of human processing is found on some tools, including wear patterns and soil residues containing plant starch grains, confirming their primary function for digging underground plant food [7][12]. Group 3: Broader Implications - This research suggests that wooden tools were crucial for early human survival strategies in tropical and subtropical environments, revealing unique resource utilization strategies [12]. - The findings challenge previous notions that early wooden tools were primarily hunting implements, indicating a broader range of uses, particularly in plant-based food processing [12].
