- W2414393557 abstract "The evolution of C 4 grassland ecosystems in eastern Africa has been intensely studied because of the potential influence of vegetation on mammalian evolution, including that of our own lineage, hominins. Although a handful of sparse vegetation records exists from middle and early Miocene terrestrial fossil sites, there is no comprehensive record of vegetation through the Neogene. Here we present a vegetation record spanning the Neogene and Quaternary Periods that documents the appearance and subsequent expansion of C 4 grasslands in eastern Africa. Carbon isotope ratios from terrestrial plant wax biomarkers deposited in marine sediments indicate constant C 3 vegetation from ∼24 Ma to 10 Ma, when C 4 grasses first appeared. From this time forward, C 4 vegetation increases monotonically to present, with a coherent signal between marine core sites located in the Somali Basin and the Red Sea. The response of mammalian herbivores to the appearance of C 4 grasses at 10 Ma is immediate, as evidenced from existing records of mammalian diets from isotopic analyses of tooth enamel. The expansion of C 4 vegetation in eastern Africa is broadly mirrored by increasing proportions of C 4 -based foods in hominin diets, beginning at 3.8 Ma in Australopithecus and, slightly later, Kenyanthropus . This continues into the late Pleistocene in Paranthropus , whereas Homo maintains a flexible diet. The biomarker vegetation record suggests the increase in open, C 4 grassland ecosystems over the last 10 Ma may have operated as a selection pressure for traits and behaviors in Homo such as bipedalism, flexible diets, and complex social structure." @default.
