New geochemical data from the Malawi Rift (Chiwondo Beds, Karonga Basin) fill a major spatial gap in our knowledge of hominin adaptations on a continental scale. Oxygen (δ18O), carbon (δ13C), and clumped (Δ47) isotope data on paleosols, hominins, and selected fauna elucidate an unexpected diversity in the Pleistocene hominin diet in the various habitats of the East African Rift System (EARS). Food sources of earlyHomoandParanthropusthriving in relatively cool and wet wooded savanna ecosystems along the western shore of paleolake Malawi contained a large fraction of C3plant material. Complementary water consumption reconstructions suggest thatca.2.4 Ma, earlyHomo(Homo rudolfensis) andParanthropus(Paranthropus boisei) remained rather stationary near freshwater sources along the lake margins. Time-equivalentParanthropus aethiopicusfrom the Eastern Rift further north in the EARS consumed a higher fraction of C4resources, an adaptation that grew more pronounced with increasing openness of the savanna setting after 2 Ma, whileHomomaintained a high versatility. However, southern AfricanParanthropus robustushad, similar to the Malawi Rift individuals, C3-dominated feeding strategies throughout the Early Pleistocene. Collectively, the stable isotope and faunal data presented here document that earlyHomoandParanthropuswere dietary opportunists and able to cope with a wide range of paleohabitats, which clearly demonstrates their high behavioral flexibility in the African Early Pleistocene.
