From The Guardian, Tuesday 6th June:

Evolution has left humans with a finely honed ability to spot angry faces in a crowd, researchers have found.

Tests
with images showing a variety of expressions have revealed that while
both sexes pick out anger in faces more quickly than any other emotion,
men are much faster at identifying signs of anger.

The effect is believed to be an evolutionary legacy acquired as men fell into conflict with each other over women and resources.

The same study showed that women were faster at spotting unthreatening
facial expressions such as happiness, sadness or disgust, a possible
result, according to the researchers, of a different evolutionary
pressure, to maintain cooperative social groupings.
