Humans are not nearly as furry as our closest primate relatives, a fact that has puzzled evolutionary biologists for more than a century.
Hhairy common theory for our relative hairlessness suggests that women long ago adopted a preference for less hairy guys as a way to avoid lice and other nasty bloodsuckers that might call a pelt home. But new research suggests that this so-called "ectoparasite avoidance hypothesis" do guys like hairy women not explain the evolution of human hairlessness.
In fact, women prefer relatively hair-free guys across the board, according to new research published online Do guys like hairy women. This preference for smooth skin holds whether or not parasite risk is high. Prokop and his colleagues asked Turkish and Slovakian women to rate the attractiveness of men with hairy and hairless chests.
To keep the men's appearance as consistent as possible, the researchers had men photographed from the neck to the waist with hairy chests, and then asked them to shave before posing for an identical photograph. Turkey was chosen because the country has a higher rate of parasite-transmitted diseasessuch as malaria and dengue fever, than Slovakia and has long had more instances lkie these illnesses, the researchers wrote.
The researchers expected hwiry find, then, that Turkish women would be more sensitive to parasite concerns and prefer less-hairy men than their northerly do guys like hairy women in Slovakia, where parasites are less of an issue.
Instead, the researchers found that very few women in either country prefer a hairy chest. Only about 20 percent of women rated the more hirsute versions of the men as more attractive. Before the ectoparasite hypothesis for hairlessness is ruled out, researchers need to test a broader do guys like hairy women of countries, Prokop said.
Earlier studies suggested women's hair preferences womej differ by country and even U. Some research even suggests women in fertile phases of their menstrual cycles are attracted to less hair on men than women in less-fertile phases, who prefer a slightly hairier look.
Live Science. Women tend to prefer men with less body hair, but researchers have yet to pin down an evolutionary reason for this preference.
