Investigating the Global Pattern of Language Diversity: Contemporary Evidence of Evolutionary Trajectories

This study investigates the contemporary evolutionary trajectories underlying the global distribution of linguistic diversity. The current spatial configuration of world languages is analyzed, with particular attention paid to the accelerating attrition of endangered languages and the dynamic interplay between linguistic evolution, human migration, and sociocultural transformations. The systemic impacts of globalization processes on linguistic ecosystems are critically examined. From an interdisciplinary framework incorporating cognitive neuroscience, computational modeling (including AI-driven methodologies), and gene-culture coevolution theory, novel theoretical and methodological advancements in diachronic linguistics are evaluated. Current research limitations are identified, and empirically grounded future directions are proposed. The findings aim to establish an evidence-based foundation for both theoretical development and policy formulation regarding the conservation of linguistic diversity.
