Core Insights - The article discusses significant archaeological findings related to ancient human ancestors, particularly focusing on the discovery of the "Dragon Man" and the implications of these findings for understanding human evolution and dietary practices [4][8]. Group 1: Discovery of "Dragon Man" - The "Dragon Man" fossil, a nearly complete skull found near Harbin, China, dates back to no later than 146,000 years ago and is linked to the Denisovans, a previously mysterious ancient human group [4][7]. - The identification of "Dragon Man" provides insights into the interactions of ancient human populations in East Asia and raises questions about their role as ancestors of modern East Asians [8]. Group 2: Dietary Practices of Ancient Humans - A significant archaeological discovery at the Jiangchuan site in Yunnan revealed 35 well-preserved wooden tools dating back approximately 300,000 years, alongside stone tools and animal remains, indicating a diverse diet and advanced tool-making capabilities [9][11]. - The analysis of these wooden tools suggests that ancient humans not only hunted but also engaged in gathering activities, showcasing a balanced diet that included both animal and plant sources [12]. Group 3: Winter Survival Strategies - Research on small bone tools from the Water Cave site indicates that ancient humans had developed techniques for processing animal hides, essential for making winter clothing and shelter [14][15]. - The findings suggest that these ancient populations employed a sophisticated resource management strategy, preparing multiple types of resources to improve living conditions and ensure survival during harsh winters [17].
