The Human Throat and Larynx

The human throat has been modified to facilitate speech. We have a resonating chamber for vocal sounds about an inch and a half in length above the larynx. The range of sounds which the human vocal apparatus is able to produce--from animal-like growls and screeches to the perfect pitch of an opera singer--is truly amazing.

Adaptation of the human throat for speech also permits choking while eating or drinking--a danger most creatures do not have to fear.
