Abstract
The Pleistocene Epoch, extending from approximately 2.58 million to 11,700 years before present, represents one of the most consequential periods in human and environmental history. Characterized by repeated glacial and interglacial cycles, this epoch witnessed profound climatic oscillations that reshaped terrestrial landscapes, altered ecological systems, and influenced the distribution of flora and fauna across continents. These environmental transformations played a decisive role in shaping patterns of human migration, adaptation, and settlement. Rather than acting merely as a backdrop to human development, climatic fluctuations actively structured opportunities and constraints that guided the movement of early hominin populations through diverse geographical environments.
This paper examines the relationship between Pleistocene environmental change and the spatial foundations of human history through a historical-geographical perspective. Particular attention is given to the influence of glacial advances and retreats, changing sea levels, shifting vegetation zones, and fluctuating precipitation regimes on migration corridors and settlement formation. The study explores major dispersal routes from Africa into Eurasia, the occupation of new ecological niches, and the emergence of regional settlement systems in response to changing environmental conditions. It further evaluates the adaptive strategies employed by prehistoric populations to cope with climatic instability, including technological innovation, mobility, and resource diversification. The paper argues that environmental transformations during the Pleistocene were fundamental drivers of human spatial organization. Understanding these interactions provides critical insights into the origins of human adaptability and the long-term relationship between environmental change and societal development.
