Paleoanthropologists have long speculated about the role of environmental change in
shaping human evolution in Africa. In recent years, drill cores of late Neogene lacustrine …

Anthropogenically elevated CO2 (eCO2) concentrations have been suggested to increase
woody cover within tropical ecosystems through fertilization. The effect of eCO2 is built into …

Characterizing eastern African environmental variability on orbital timescales is crucial to
evaluating the hominin evolutionary response to past climate changes. However, there is a …

Expanding grassy ecosystems through the late Cenozoic may have driven ecological and
evolutionary change in hominins and other African mammals. However, we lack a …

The most profound shift in the African hydroclimate of the last 1 million years occurred
around 300 thousand years (ka) ago. This change in African hydroclimate is manifest as an …

Eastern Africa has played a prominent role in debates about human evolution and dispersal
due to the presence of rich archaeological, palaeoanthropological and palaeoenvironmental …

Abstract The Early-Middle Pleistocene Transition (EMPT) between 1200 and 700 ka
