If You Raise Your Eyebrows While Looking in a Mirror

Question

If you raise your eyebrows while looking in a mirror, you will also
A) See your ears rise up because the same muscles are involved in eyebrow raising and ear raising
B) See your ears rise up because, according to Darwin's theory of evolution, humans evolved from animals and the animals with which humans share evolutionary ancestors also perk up their ears and raise their eyebrows in response to unexpected sounds
C) See your ears raise because of mirror neurons
D) a and b

Accepted Answer

The correct answers are A and B because both the involvement of similar muscles in eyebrow and ear movements and Darwin's theory regarding evolutionary traits shared with animals explain why you might observe your ears rising when you raise your eyebrows. Darwin's theory suggests that certain expressions and reactions are evolutionary remnants from our animal ancestors, including the simultaneous movement of ears and eyebrows in response to stimuli.
