Loss of air sacs improved hominin speech abilities

Journal of Human Evolution, 2012
In this paper, the acoustic-perceptual effects of air sacs are investigated. Using an adaptive hearing experiment, it is shown that air sacs reduce the perceptual effect of vowel-like articulations. Air sacs are a feature of the vocal tract of all great apes, except humans.

Sisters of the Sinuses: Cetacean Air Sacs

The Anatomical Record, 2008
AbstractThis overview assesses some distinguishing features of the cetacean (whale, dolphin, porpoise) air sac system that may relate to the anatomy and function of the paranasal sinuses in terrestrial mammals. The cetacean respiratory tract has been modified through evolution to accommodate living in water.

THE PERCEPTUAL EFFECT OF AIR SACS

The Evolution of Language, 2010
This paper presents work on air sacs that extends the work presented by de Boer, (2008a). In that paper, and before (Fitch, 2000) air sacs were identified as a likely feature of our evolutionary ancestors that may have been lost because of the evolution of speech.
