According to a study by the London School of Economics, good-looking couples are 26 per cent more likely to have a daughter rather than a son for their first child, reported the London Times.And scientists believe this is why women have become increasingly more attractive than men over the years.
The bias towards having daughters has to do with differing 'evolutionary strategies' that each sex has adopted to survive, said the researchers.
They reason that the first-born of aggressive, high-status parents tend to be boys because they are better equipped to protect their family line and outwit competitors when it comes to finding a mate.
BEAUTY AS A WEAPON
However, the likelihood of having a daughter is mostly dependent on the parents' youth and attractiveness. These girls can then use their beauty to attract the best mates and hang on to them.
'We have shown two things,' said Dr Satoshi Kanazawa, who led the research.
'Beautiful parents have more daughters than ugly parents, because physical attractiveness is heritable and because daughters benefit from attractiveness more than sons.
'We have also shown that women on average are more attractive than men, because over evolutionary history, the slight bias of beautiful parents to have more daughters has accumulated, so that girls have become more and more attractive than boys.'
The report, published in the Journal of Theoretical Biology, also argues that youth and physical attractiveness matter more to a man when choosing his mate than status or wealth.
Researchers analysed more than 20,000 people in the US and rated their beauty according to height, weight and apparent age - all factors that can be used to judge basic attraction levels without subjective viewpoints.
Only first-born children were included in the analysis.
Dr Mark Thomas, senior lecturer at the biology department of University College London, said the LSE study appeared to 'fit in' with the state of research on sexual evolution.
Good-looking Hollywood couples who have lent weight to the theory include Brad Pitt and Angelina Jolie, Reese Witherspoon and Ryan Phillippe, and Tom Cruise and Katie Holmes.
Outside Hollywood, researchers pointed to Prince Rainier of Monaco and actress Grace Kelly who had the beautiful Princess Caroline.

You do not have to give up your cat if you are pregnant, according to the Centers for Disease Control and Prevention Web site.
Many pregnant women have gotten rid of their cats because cats can spread toxoplasmosis, which is an infection caused by a parasite. If a pregnant woman is exposed to the parasite, she can pass the infection to the fetus, and the baby could be mentally retarded or blind or have epilepsy.
Doctors have been known to tell pregnant women to get rid of pet cats.
The Humane Society of the United States in 2004 embarked on an educational campaign that included mailing brochures to 31,000 members of the American College of Obstetricians and Gynecologists. Facts and "myths" were spelled out in the brochure, and doctors were asked to spread the message that pregnant women do not have to give up their cats.
The brochure was written by Dr. Jeffrey D. Kravetz of the Yale University School of Medicine.
The parasite Toxoplasma gondii, which causes toxoplasmosis, can be found in the feces of cats that eat raw meat, birds or mice that harbor the parasite.
According to the CDC:
Toxoplasmosis is very rare in this country, and a simple blood test will reveal whether you were exposed to toxoplasmosis during your pregnancy.
Pregnant woman can be exposed to toxoplasmosis by eating raw or undercooked meat or from gardening in soil contaminated with the parasite.
Indoor cats are highly unlikely to pick up the parasite, but don't get a new cat or kitten while you are pregnant because you have no way of knowing whether it has been exposed to the parasite.
Raw meat fed to cats can be a source of toxoplasma infection.
Ideally, the cat litter box should be changed by someone other than the pregnant woman.
Wear disposable gloves, and thoroughly wash your hands with soap and water if you do change the litter box.
Thoroughly wash hands after any exposure to soil, sand, raw meat or unwashed vegetables.
Wash and peel fruits and vegetables before eating them.Source: Post-Gazette
