Research suggests that orbital controls played a role in shaping the hydroclimate of eastern Africa during the Pleistocene era. Studies based on various records, including speleothem and lake data, indicate that hydroclimate variability in the region was influenced by multiple factors, including high-latitude and Indian Ocean conditions. The findings also imply a potential link between hydroclimate changes in eastern Africa and early human dispersal, although the specifics of these relationships are still being explored.
