As generations of men with two left feet have learned to their cost, having the dance floor prowess of Mr Bean is no help in the mating game.
To make matters worse for the terminally uncoordinated, it now looks as if women are right to go for men who can strut their stuff like John Travolta or Patrick Swayze - as they are more likely to be strong and to produce healthy offspring.
Nadine Hugill and Bernhard Fink of the University of Göttingen in Germany found that men whose dancing was rated as attractive and assertive by women were physically stronger than those whose moves were dismissed as below par. "We already know women use static cues such as facial and bodily characteristics in their assessments of men," says Fink. "This study shows that dynamic cues such as dancing ability might also be used to assess male quality in terms of strength and dominance - traits which eventually signal status."
The researchers recorded video clips of 40 heterosexual male students dancing to the drum track of the Robbie Williams song Let Me Entertain You. Participants wore white overalls, and a blurring filter was used to disguise information about their clothing, as well as face and body shape. Hand grip strength was measured using a dynamometer.
Twenty-five female students viewed the muted videos and rated the attractiveness of the dancers, while another 25 rated their assertiveness. Even after controlling for body weight, there were strong correlations between strength scores and both perceived attractiveness and assertiveness.
Fink had already discovered that men who were exposed to higher levels of testosterone in the womb, as indicated by the relative lengths of their index and ring fingers, were rated as more attractive, dominant and masculine by women who watched clips of them dancing. Research also shows that women generally find very masculine facial features more attractive, particularly around ovulation.
"This would make sense from an evolutionary perspective. Being able to select high-quality males on the basis of visual cues is likely to have promoted certain females through sexual selection," says Gayle Brewer, an evolutionary psychologist at the University of Central Lancashire, in Preston, UK.
However, all is not lost for those not blessed with twinkle toes. "If you are unable to compete, change the game. Perhaps stay away from the dance floor and show your qualities in other ways by buying a woman a drink or showing how attentive and engaging you are," says Brewer.
Introduction and Conclusion can cause the biggest problems for your research paper at college or university. You will be surprised, but the research part is not the most difficult one for a lot of students. The biggest problems they face when writing an Introduction and Conclusion. They don't know what can be included and what can't be included in these parts, while keeping a healthy balance between an introduction, body, and conclusion in terms of word count. Read more
Given the individuality and uniqueness of every person, some things in life have to be unified. White collars are to dress in the classic style to work, while pupils wear school uniform on a daily basis. This allows for consistency and accuracy in their respective institutions just like the formatting does in writing. For clear and digestible expression of ideas, essays follow a certain structure, consist of particular elements, and have a special layout. Read more
Bike ride is the most elementary form of transport. In earlier days, it was the first human powered vehicle that later transformed the face of automation. The first bicycle appeared around 400 years ago. Slowly innovation and technology shaped the rudimentary bicycle into the modern day road bike that we are so accustomed to see. Read more
