Did our earliest hominid ancestor begin to walk on two legs in forests, woodlands or grasslands? A new model of the relationship of the carbon isotope ratios of soil to the proportions of tree versus C4 grass cover in tropical savannas produces results consistent with a model of bipedal origins in grassy savannas. However, this model was developed using data mainly from floral habitats on infertile sandy soils, and may be irrelevant for fossil sites in regions with fertile soils.
