Pleistocenen
Pleistocenen, known in English as the Pleistocene, is the earliest epoch of the Quaternary period. It spans from about 2.58 million years ago to approximately 11,700 years ago. The name derives from Greek and reflects its place as the most recent major division of the geologic timescale.
The epoch is characterized by repeated cycles of cooling and warming, leading to alternating glacial and interglacial
Biologically, the Pleistocene witnessed significant evolutionary and behavioral developments. It includes the emergence of Homo sapiens
Subdivisions of the Pleistocene are defined in terms of stages or ages, commonly Gelasian, Calabrian, Ionian,
