Cover image: Pictured are hominin fossils from sites within the Turkana Basin in Kenya. Four articles in the Early Hominin Diet Special Feature illustrate how stable carbon isotopes present in the dental enamel of such fossils can reveal the diets of hominins that lived in Africa between roughly 4.1 and 1.3 million years ago. The papers found evidence of a shift from a diet dominated by leaves and fruits from trees, shrubs, and bushes to one that featured an increased proportion derived from grasses or sedges. Clockwise beginning at the top left are crania from Paranthropus boisei, Homo sapiens from the Holocene, Homo ergaster, Homo rudolfensis, Kenyanthropus platyops, and Paranthropus aethiopicus. At the bottom is a single mandible from Australopithecus anamensis. See the Commentary by Richard G. Klein on pages 10470–10472.
