Another similarity would be the capabilities of speech.

• With the discovery of a hyoid bone in Kebara Cave in Israel, scientists have been able to reconstruct the Neanderthal esophagus and deduce that they could indeed speak. The space between the tongue and the throat was smaller than our own, which indicates that they communicated with high pitched, nasally voices contrary to the brutish tones that they are attributed in sci-fi flicks.
