Not much, it seemed to Gregory Clark when he was first thinking about why the Industrial Revolution started in Britain, rather than in China, say, or India. Clark, an economist at the University of California at Davis, knew that in the past, British cities had an appalling mortality rate and prospered only by consuming a large annual crop of newcomers from the countryside. So he assumed that modern British people were, as he put it in a recent interview, "the remnants of rural idiocy"—that is, descended from less energetic, less educated types who stayed put on their farms. (The assumption was perhaps a byproduct of Clark's having grown up in an Irish Catholic family in Scotland, a pedigree unlikely to produce either Anglophilia or an admirer of the rich.) But his opinion changed when he undertook a detailed analysis of 3,500 British wills from 1250 to 1650, looking particularly at wealth and reproduction.
"To my surprise, there was a very powerful effect," says Clark. "The wealthy had many more children." He wasn't looking at the aristocracy, who tended to get killed in wars and power struggles (or to wane because of reproductive ennui). Instead, he looked at the enterprising gentry, people a notch or two down the social hierarchy, who devoted their lives to commerce and died in bed. "They had four surviving children in a society where the average was two," Clark says.
Other researchers have argued that the Industrial Revolution got started, in Britain in the 18th century, on the strength of coal and colonies. But in his new book, A Farewell to Alms, Clark proposes that what really made the difference was this "survival of the richest." In the relatively stable British climate after 1200, with limited resources and little population growth, "the superabundant children of the rich" inevitably moved down the economic ladder, displacing poor families. And something of their privileged past went with them. "The attributes that would ensure later economic dynamism—patience, hard work, ingenuity, innovativeness, education—were thus spreading biologically throughout the population," Clark writes.
This change may well have been "completely cultural," Clark says. But he is clearly more interested in the possibility that Darwinian evolution—with disease, accidents and starvation driving less successful families onto the scrapheap of history—produced a genetic change in the British people, preparing them better than those of other nations for commercial success.
He readily acknowledges that the idea is fraught with difficulty. A faculty petition had just prompted his university to disinvite a scheduled speaker, economist and former Harvard president Larry Summers, because of Summers' profoundly controversial 2005 suggestion of a genetic difference in science aptitude between men and women. This all makes Clark uneasy, he says, because his book "suggests that there might be a genetic difference between Europeans and Australian aboriginals." Then he adds: "Not that Europeans are smarter, just that they may be better adapted to a capitalist society."
An adaptation that particularly interests Clark has to do with "time preference," which can take the form of patience and long-term planning in some people and an impulsive urge for immediate gratification in others. When forms of such a trait already exist in a population, Clark says, natural selection could rapidly make one form predominant, just as blue eyes or fair skin can come to predominate. Thus the surplus reproduction of the rich may have turned England into the birthplace of industrial manufacturing by replacing impulsive traits with the slow and steady. "It may just be the drudges that have been left," Clark says. (Maybe that's why the British became known as a "nation of shopkeepers.")
But why didn't the same kind of evolution take place in other countries? In China and Japan, the rich seem not to have been so fertile, Clark writes. (The historical data for India doesn't exist, as far as he knows.) Moreover, the population in China tripled in the centuries before the Industrial Revolution, and in Japan it quintupled. So natural selection may not have been killing off the poor quite so remorselessly as in Britain, where the size of the population remained the same.
Other scholars have praised the detailed research and ambitious scope of Clark's work. But they have also questioned whether genetic, or even cultural, transmission of behavioral traits from rich ancestors is enough to explain the Industrial Revolution. Economists still generally argue that good institutions are the primary factor in such big leaps forward, because they make people feel sufficiently secure to focus patiently on long-term gain. And recent evidence suggests that when institutions change, as they have in China, Japan and India, people there seem quite capable of adapting to capitalism.

OK...So, how does on explain Paris Hilton: Recessive gene?

The recessive gene theory is a valid assumption . Along the same idea , how do we explain a person who is extremely bright ,who has the desire to be very wealthy , the lust for power but has no motivation to follow these desires and the behavior becomes self destuctive ?

As Hemingway said to Scott Fitzgerald, 'The rich are different from you and me',with an air of moral superiority,to which Fitzgerald replied,'Yes they have more money'.

An interesting idea when one considers it along Malow's hierachy of needs. Throughout history the common people have had to struggle just to survive and there was no excess for enrichment. The wealthy in society have provided the monetary backing for scientific or cultural schools, studies or expeditions with the goal being self-aggrandizement, and/or power or wealth increase. One can see the rich DID propel the advances in society although it was for their own benefit. If this is behavior that is genetically driven, rather than learned, I'd say it's a pity for the human race as a whole. Does it account for the prevalence of selfishness over altruism? Greed over generosity? More valuable to a society is the ability to do the right thing because it is the right thing to do without the need for recognition or reward. My son heard somewhere that altruistic people are genetically different than self-serving people. He posits that the altruistic are a mutation. Is there evidence of altruism in wild animals?
