Caption

Reconstructed hearing patterns in modern humans, Neandertals and the Sima de los Huesos based on their ear anatomy. Compared with their ancestors from the Sima de los Huesos, the Neandertals more closely resemble modern humans in showing a heightened sensitivity between 3.5-5 kHz, a frequency range that contains acoustic information related to consonant production in human spoken language.
