We’ve all done it. We have all seen it. She is the «face of anger», of anger, fury, rage, or whatever you want to call it. And now scientists say that it seems to be part of our basic biology as human beings rather than a cultural reaction.

Researchers at the University of California at Santa Barbara (known as UCSB or UC Santa Barbara) and Griffith University in Australia identified «functional advantages that led to the evolution of the specific appearance of the anger face,» explained the center of American studies on his website.

«The expression is in every culture, and even children with congenital blindness make the same face without ever having seen one,» explains lead study author Aaron Sell, a professor at Griffith University’s School of Criminology and a former investigator for the UCSB Center for Developmental Psychology.

And the face of anger is more than a display of anger, but has evolved to perform the signals of strength of the human being.
