NEW YORK :It may not be as threatening as a lion’s roar or a
snake bare its fangs, but scientists now believe that the human ‘’angry face’’
evolved to make us look ‘really dangerous’.
The glower people pull when they are exasperated may be more
than a way of communicating their frustrations, Santa Barbara have found at the
University of California,.
lowered eyebrow, Flared nostrils and a jutting jaw are all
characteristics that make a person seem physically stronger, and may have been
used to make opponent back down in times gone by.
The academics believed that scowls developed as a show of
strength rather than a way of showing frustrations.
According to ‘’The Times’’, Aaron Sell, who lead the
research, said: ‘The reason natural selection designed [the angry face] is that
the individuals who made the face out-reproduced the other ones.’
‘They out-reproduced them because the people who made that
face won their conflict. and other people back down because they thinking that,
“Woww, he looks really Strong.”
Doctor Sell added. ‘In many animal kinds, before aggression,
animals will pose in ways that enhance the cue of fighting ability that they
have.
‘Hair can stand on edge to make the mammal seem larger; lips
are pulled back to make fangs look as large as possible.’
The new lessons, published in the Evolution and Human
Behavior, involved scientists testing different features of the angry face on
people’s expressions.
Experts said the 7 characteristics of the human scowl are flare
nostrils, thinned lips, the chin pushed up and out, the cheekbone and mouth
raised, and the brow lowered.
They gradually added the features to a computesimulated
face, asking volunteers to say which person looked the strongest.
volunteers said the face with more ‘angry facial appearance’
belong to stronger men.
Dr Sell said: ‘Since people are judged to be stronger tend
to get their way more regularly, and other things being equal, then we concluded that the explanation for
evolution of the form of the human anger face is surprisingly simple , it is a
threat display.’
Another study of the angry face in 2005. suggested that the
look made people emerge more threatening as they seem older.
Dr Sell’s researches
contradicts their findings, as another experiment by his team found that people
did not rate the computer generated angry faces as any older than impartial
control images.
