There is no wonder then that men find women with feminine facial features more attractive than other women.
They used 1,721 vocal calls, free of background noise, from individuals of known species, sex and adult status.
They used mating systems --monogamous, promiscuous or polygynous -- as a proxy for the intensity of sexual selection.
"We find that masculine traits in humans are not the same as, say, in peacocks where the beautiful tail attracts a mate," said Puts.
"For example, beards make men more dominant looking, scarier and seemingly more dangerous, but most women prefer clean-shaven men." Human male traits imply physical aggression and formidability and seem to provide competitive advantages in fighting or threatening other men more than they help attract women.
