“By analyzing teeth and carbon remains from isotopes from fossil specimen Australopithecus sediba, German scientists discovered early humanity chewed bark. The immediate ancestor of the human lineage may have lived off a woodland diet of leaves, fruits and bark instead of a menu based on the open savanna as other extinct relatives of humanity did, researchers say. Food was a major environmental force that shaped the human lineage – perhaps influencing key moments such as when humans’ ancestors started walking upright – and these new findings help reveal the complex evolutionary paths these ancestors took in response to the world around them, the scientists add.” w/ photos + video
