Vestigial ear muscles activate during focused listening, revealing a hidden link to our auditory past and evolution.

If you can wiggle your ears, you can use muscles that helped our distant ancestors listen closely. These auricular muscles helped change the shape of the pinna, or the shell of the ear, funneling ...

Similar research has already shown that the largest muscles, posterior and superior auricular muscles, react during attentive listening. Because they pull the ears up and back, they are considered ...
