Evolutionary simplification in the human larynx – the loss of vocal membranes and air sacs common to all nonhuman primates – enabled the increased acoustic complexity required by human speech, ...

The evolution of the human larynx contributed to the stable voices we use to communicate. The morphological changes do not include the addition of structures but rather the loss of specific vocal ...

Monkeys known as macaques possess the vocal anatomy to produce "clearly intelligible" human speech but lack the brain circuitry to do so, according to new research. The findings — which could apply to ...

Say what? Doctors have grown the world’s first vocal cords from scratch. The breakthrough could one day restore speech to people who have lost their own vocal cords through surgery or disease. Doctors ...

Researchers say they’ve grown new sets of vocal cords from just a few cells, and think they might be able to create custom-grown replacements for people who have lost their own voices. The highly ...

Vibrating tissue that hums in tune with normal, human vocal cords has been grown in a lab for the first time. The bioengineered tissue opens a route to developing new therapies for people who have ...

Dysphonia, or voice problems, is a disorder that gets little attention in the public imagination. Loss of speech is not life-threatening. And because it is often a consequence of other health issues ...

An ongoing debate among scientists, on why chimpanzees and other nonhuman primates cannot speak or sing like humans, has focused mainly on evolutionary changes in human brain development. Attention ...
