Intimidating men attractive
Promiscuity differs from monogamy and polygyny in that females more frequently have multiple sex partners, which makes predictions of sexual dimorphism more difficult.In polygynous species, some males can monopolize many mates leaving other males unmated. -- Male voices are not deeply pitched in order to attract female mates, but instead serve to intimidate the competition, according to a team of researchers studying a wide variety of primates including humans."We wanted to determine if sexual selection had produced sex differences in humans and closely related species," said David A."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.Puts, associate professor of anthropology, Penn State.
In other words men are biologically wired to find the feminine female more attractive than the less feminine female.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.Next the researchers looked at 258 female and 175 male college students who read a standard passage that was recorded without any background sounds. Each female recording was rated by 15 men for the potential for short- and long-term romantic attractiveness using a standard rating system.Each male recording was rated by 15 men for dominance and 15 women for short- and long-term romantic attractiveness.
