For example, in the reign of Queen Victoria in England, a cluster of birds beautiful lips is the pinnacle of beauty. Today, the tiny lips were replaced by energy-consuming mouth that Western women are always looking to his lips as "swelling" as possible.
In many societies, the point of sexual arousal has spread to both ankles, neck, knee; how to do hair, makeup and fashion change over.
Desirable form of women was changing, partly stemming from the social advancement of women. By the 50s of last century, Marilyn Monroe as a model of sensuous beauty, but today she will be advised to take exercise to lose weight.
So, it seems that beauty standards do not exist - there is no eternal standard or just a certain move.
But with the evolution of physiology has not happened.
For them, fashion is just a flimsy cover for a deeper power, uncompromising and unchanging, also old and enduring as our genes. That is the basic motivation for Darwinian humans survive and be healthy.
In a verification of this hypothesis opposition, scientists at the University of Texas at Austin and Harvard University, USA, has left over 3 continents century English literature and literary classic Asian nearly two thousand years ago. The goal is to learn parts of the body are women authors repeatedly praised over the years.
Breasts, buttocks and thighs - the erotic key areas - the presumption will prevail in the core of this work. But in the end, a slender waist to beat all.
In English literature, the passage portrays a slender waist ("small stick", "being deluded by her lovely waist" ...) appears 65 times. Meanwhile, romantic passages describing breasts appear 16 times, 12 times and slender thighs only 2 pieces about hips and buttocks.
However, these works are still flooded with praise plump beauty that comes to the slender little. The remarkable thing here is that both women plump or slender, petite waist remains the focal point. No other details depicted with reverence beauty that speaks of belly bulge.
In the works of Asian, slim waist even more revered. The small waist is mentioned 35 times in the second to take the Indian epics. In Chinese poetry, slim waist was honored 17 times, while breasts, buttocks, hips and thighs are not mentioned at all, and only a paragraph describing exclusive romantic woman's legs.
The study concluded that the waist is a symbol of passion to overcome time and space.
Why so?
The answer according to the authors is that a small waist is a sign of good health and high fertility. Men have always instinctively assess a woman's waist as a sign of their ability to generate healthy children.
Modern research also showed an association between obesity and increased disease, declining estrogen levels, and also reduced fecundity.
"Despite the continuous change in the concept of beauty, a sign of good health and reproductive success - a slim waist - has always been a symbol of immutable feminine beauty", the researchers concluded.
