If you are one of those men who looks in the mirror in the morning and doesn't like what he sees, take heart.
Women are genetically programmed to pick brains over brawn when it comes to choosing a mate, say scientists.
The female of the species is, the experts say, responsible for the intelligence of the human race.
Historically, women have spurned the bronzed Adonis and instead plumped for men with wit and intelligence, according to a report published today.
The theory might help explain how balding, bearded author Salman Rushdie - no oil painting in anyone's book, but acknowledged as a giant of literature - managed to charm the model Padma Lakshmi.
Or why Marilyn Monroe found the bespectacled playwright Arthur Miller, who was awarded the Pulitzer Prize in 1949, sufficiently beguiling to marry.
German geneticists say by favouring intelligence over strength and looks, our female ancestors set in motion a process that, over thousands of years, has developed the modern human brain.
Dr Horst Hameister and Dr Ulrich Zechner, of the University of Ulm, claim to have found evidence that the way women select men means the human race has built up more and more genes for intelligence.
Their sexual selection process, running hand in hand with the fact that brighter individuals are more likely to survive anyway, has resulted in a tripling in the size of the human brain over 2.5million years, say the scientists.
Other studies have indicated that women prefer brain over brawn when selecting a mate.
A Californian study shows that women who are not on the Pill favour intelligent, creative men when they are most likely to conceive, and men with greater wealth at other times of the month.
Human evolution occurs when a genetic mutation makes an individual more 'successful', and therefore attractive to potential mates.
According to a report in the magazine New Scientist today, the German researchers claim to have discovered evidence that women are more likely to be attracted to men who have a genetic mutation that increases their potential for intelligence.
As a result this genetic mutation, they suggest, is programmed to survive better than other traits which may or may not attract women.
The scientists claim that intelligence genes are concentrated on the X chromosome, one of the 23 pairs that every human possesses. Females have two X chromosomes and males have an X and a Y.
In women, a mutation would be cancelled out by the other X chromosome but in men its presence would be 'expressed' because there is no corresponding gene on the Y chromosome.
Those with the intelligence mutation would be more attractive to women and more likely to pass on the gene. Eventually it would become so common that women would start acquiring two copies, allowing them to express it.
'Humanity should be grateful, men especially,' said New Scientist.
'For if female ancestors had preferred bright red rumps, men might still be sporting these and keeping company with gorillas and chimps.'
