Abstract (fachliche Beschreibung):


The environmental hypotheses of human evolution postulate that climate-derived environmental

changes and tectonic forcing were the driving factors of the evolution of African fauna, including

early humans. In these models, major evolutionary events were associated with African climate

change at 2.7-2.5 Ma, 1.9-1.6 Ma and 1-0.7 Ma intervals, which appear to coincide with the

timing of key evolutionary milestones in human history. Recent scientific drilling in various

paleolakes of the East African Rift has produced multiple high-resolution records of climate

variability, which can be used to reconstruct the regional climate history. However, previous

attempts to test the environmental hypotheses by applying this record directly to human evolution

have been limited by the difficulty of linking core records directly to time-equivalent outcrops

containing the fossil and archaeological record. We will therefore apply a novel approach

in archaeology - a combination of tephrostratigraphic and sequence stratigraphic concepts.
