Target entity: Pleistocene
Context triple: [Bolshoy Lyakhovsky Island, geologicalPeriodEvidence, Pleistocene]
  • A. Pleistocene epoch chosen
    The Pleistocene epoch was a geological time period characterized by repeated ice ages, widespread glaciation, and the evolution and global spread of modern humans.
  • B. Quaternary period
    The Quaternary period is the most recent division of geologic time, characterized by repeated ice ages, the evolution and global spread of modern humans, and significant climatic fluctuations over the last 2.6 million years.
