Trends among the bearded face of the man at the moment igad seems not to last long. A study in Australia showed beard just looks interesting if rare to find, but conversely if too many men who appeared with bearded face, the beard is reduced attractiveness.
Based on the study published in the Royal Society journal Biology Letters says that the thrust of this research concludes the evolutionary forces behind the rise and fall instrumental charm display bearded igad face and other facial hair pattern in men. .
"In igad a world filled with bearded men, beards be seen less sexy than a world full of men who are clean-shaven face," says evolutionary biologist, Professor Rob Brooks from the University of New South Wales.
Brooks and his colleagues set up experiments to determine whether the fashion trends beards or facial hair being loved adam is likely to change in the same way as happens with gene and the properties of living beings in the evolutionary process. igad
In particular, researchers are interested in seeing what is called a "negative frequency dependence or" Negative Frequency Dependence "which is a form of selection pressure on a gene.
Negative Frequency Dependence case occurs for example igad in the case of orchids mimic female insects to trick insects men to want to mate and pollinate them. If flowers are too successful in this strategy, sooner or later he will take the strategy of insect and stop pollinating flowers.
Brooks said the same theory also applies to fashion trends. When many people follow a particular fashion trend, then the trend becomes even more reduced in value, and what is considered trendy in popularity it will slowly recede.
In this experiment Brooks igad and his colleagues asked a number of men and women to give value to the photo online both men face clean-shaven igad face and his face adorned by a facial hair growth in a period of 5 days, the growth of 10-day or a full beard.
Participants in this study was initially shown a series of images consisting of 24 images of his face. The 24th image showing the man's face image with 4 types bearded face and his face clean-shaven face or image-filled man beard.
From this experiment Brooks and his colleagues found, among men and women look very fond of the look bearded face if the face appears a little igad pattern or a rare appearance in the period of the face image sequence.
The researchers say these findings igad suggest that the negative frequency dependence terori in the theory of evolution applies to facial hair trend among men. These findings also indicate a power boost may contribute to the evolution of the level of fondness man beard is happening now.
How does evolution actually work to date memangvmasih unclear igad but he thinks the likelihood of negative frequency dependence of this mechanism seems particularly applicable to the beard is strong enough igad compared to the number of other fashion trends such as colored hair and body size had also conducted experiments recently .
"The idea that something like this is good 'or cultural evolution' is obsolete sara think that should be no longer valid in the 20th century," he said. "And that culture evolves igad and so much evolutionary change occurs through the mechanism of culture," said Brook concluded. []
