It has been suggested that raised eyebrows are universally associated with a surprised expression because they effectively widen the eyes, enabling us to take in more information. Which theorist would have agreed with this statement?

The theorist is Charles Darwin.

Explanation:

As we know, Charles Darwin's theory of evolution claimed that organisms which are able to adapt to the environment survive. Those which are not end up extinct. Small details, therefore, can make a whole lot of difference. The eyebrows we have nowadays are an evolutionary trait that has more than just an aesthetic purpose. If raising your eyebrows when you are surprised means you can take in more information, it can also make a difference in survival. The more information you take in, the better equipped your brain is to make a decision that may determine if you live or die.
