Ancient hominid ears were tuned to high frequencies. Scientists generated a 3-D virtual reconstruction of the ear anatomy for this Paranthropus robustus skull and for two other ancient South African hominids. New findings suggest these hominids could hear high-frequency sounds needed to discern certain consonants. ~~ Rolf Quam
