A million-year-old skull found in China, known as Yunxian 2, has led scientists to propose a significant revision in the understanding of human evolution. Initially classified as belonging to Homo erectus, advanced reconstruction techniques suggest it may actually belong to a newly identified group called Homo longi, or "dragon man," which could be closely related to the Denisovans. This finding implies that modern humans (Homo sapiens) may have originated much earlier and potentially outside Africa, indicating a more

James C. Scott’s "Seeing Like a State" presents the concept of "legibility" in organizational work, distinguishing between legible and illegible tasks. Legible work is structured, predictable, and documentable, while illegible work encompasses informal interactions, tacit knowledge, and flexible adaptations that are not easily quantified. This distinction helps explain the complexities of large software companies, including their counterintuitive practices and discrepancies between official rules and actual behavior. Scott draws parallels to the "high modernist
