This article describes a recent study in which scientists were able to use CT scans to generate 3-D models of Neanderthal ear structures. In the past, attempts to determine whether Neanderthals used language hinged on the hyoid bone, a single piece of the Neanderthal vocal tract. However, these scientists took a different approach by looking at the ears of Neanderthals to give clues about Neanderthal language. By running the ear models through computer programs, scientists were able to determine that the Neanderthal ear's "sweet spot" included higher frequencies characteristic of consonant production, and therefore human language. This is exciting because it gives scientists another piece in the puzzle of early human language development.
"Did Neanderthals sing? Is there a 'music gene'? Two scientists debate whether our capacity to make and enjoy songs comes from biological evolution or from the advent of civilization. Music is everywhere, but it remains an evolutionary enigma."
From the section Science & Environment An analysis of a Neanderthal's fossilised hyoid bone - a horseshoe-shaped structure in the neck - suggests the species had the ability to speak. This has been suspected since the 1989 discovery of a Neanderthal hyoid that looks just like a modern human's.
This article reminds me of the "Singing Neanderthals" reading that we did. Perhaps whales, like babies, hear tones instead of actual words and can also perceive emotions of other whales they communicate with. If this is so, would this 'tone communication' be considered a language in of itself?
