Evolución de la laringe y el lenguaje hablado.

from Cienciaes.com

Aunque ciertas especializaciones del aparato vocal humano eran bien conocidas y comprendidas, la evolución de la laringe no había sido estudiada en detalle. Ahora, un numeroso grupo de investigadores en biología evolutiva de varios países en varios continentes han utilizado la resonancia magnética y tomografía computarizada para analizar la anatomía de las laringes de 25 géneros (como Homo o Macaca) y 43 especies de primates. Los científicos confirman que, en la laringe humana, dos pliegues del tejido, las llamadas cuerdas vocales, son las responsables de la producción del sonido. Sin embargo, el resto de los primates posee, además, pliegues adicionales en forma de aletas, llamados membranas o labios vocales, que también participan en la producción del sonido. Los humanos somos los únicos primates que carecemos de esas membranas vocales y solo producimos sonidos mediante las cuerdas vocales. Más información en https://cienciaes.com
