Research Objectives

  • Understanding the causal relationship between climate change and the natural environment, and their impact on the human population is a pressing issue of global importance
  • Consultation at GBY.
    Consultation at GBY.
    Prediction of the effects of future climate change has so far been based mostly on relatively short time spans, mainly the Last Glacial to Recent
  • This program uses a multidisciplinary approach which includes biology, geochemistry, geochronology and archaeology in order to examine the continuous record of hominin habitat over a period of 100,000 years, with a calibration of the parameters with respect to present-day climate.
  • The lakeside Acheulian site of Gesher Benot Ya‘aqov (GBY) in the Upper Jordan Valley has revealed sufficient evidence to define it as a benchmark suitable for this investigation

The Site of Gesher Benot Ya‘aqov

  • contains a well-described continuous sedimentary record, which crosses the globally identifiable Matuyama/Brunhes chron boundary at 780Ka and has a long span of ca. 100Ka of a glacial cycle. This time span includes the well-defined climate variations recorded in coeval deep-sea sediments (OIS 18-20) and most recently also the high-resolution isotope records of the Antarctic EPICA ice core, showing a large amplitude climate change
  • yielded very well preserved remains of rich and diverse lacustrine and terrestrial, floral and faunal assemblages and 13 horizons of human occupation
  • its location on the out-of-Africa migration route is pivotal in both location and in timing in the history of human evolution
  • The occurrence of edible species currently present in the region allows an understanding of the impact on food supply and hominin diet.
