Study Correlates Climate Change and Early Human Activities at The Algerian Site of El Kherba 1.7 Million Years Ago

The results of this paleoecological study indicate the occurrence of an increasingly open landscape, which is supported by the pedogenic carbonate data showing a climate change that is consistent with the documented Plio-Pleistocene continental trend of increasing aridification and grassland expansion.

The climate change likely impacted hominid foraging activities particularly in the Archaeological level A. The level A witnessed a drastic decrease in hominid activities characterized by a considerably lower density in stone tools and fossil bones as opposed to the lower level B characterized by a closed habitat and abundant archaeological materials.

“The open habitat in level A would have caused major constraints for early hominids, such as limitations for access to food supply and water as a result to their diffusion and shortage on the landscape, as well as riskier possibilities for meat acquisition due to competition with carnivores”, explains Mohamed Sahnouni.

In this The study, entitled Evidence of climate change in the Lower Pleistocene site of El Kherba (Algeria) and its possible impact on hominid activities, at 1.7 Ma, collaborators from the Centre National de Recherches Prehistoriques, Anthropologiques et Historiques (CNRPAH, Algeria), Museo Nacional de Ciemcias Naturales (Madrid), Indiana University Bloomington and Chevron Energy (USA), have also participated.
