Gene Makes People Religious

 You have heard of a gene that scientists believe makes people gay. Now, they say there's a gene-- to make you-- religious. There are a number of studies that show the faithful tend to have more kids. One study, the World Values Survey, which looked at 82 nations, found adults who attended religious services more then once a week had 2.5 kids on average. Those who never attended had 1.6 kids.  Cambridge University Professor Robert Rowthorn says if you take that fact and pair it with the existance of a genetic predisposition in some toward belief-- he says world religion will spread simply because of a believer's gene. Rawthorn says it's a D.N.A. code that makes people believe-- and not entirely the teachings of their parents.  He speculated that because the faithful have fertility rates 3 and 4 times the general population, religious groups could rapidly outpace the rest of the population and become a majority.
