HUMAN HISTORY ON THE ENVIRONMENTAL BACKGROUND

  • The cumulative probability distributions based on calibrated 14C dates:

  • 14C dates sets for Mesolithic and Neolithic sites in Poland during the last 15,000 BP

  • 14C dates sets from sediment with well-defined sedimentation conditions (speleothems, peat)

  • The grey areas show time intervals in which the climatic conditions were conducive to increased human settling.
