Research on twins supports ‘God gene’
“Religious belief is in the genes and can literally be inherited from one’s parents, according to new research.

While environmental factors were the largest influences on children, genetic make-up played a significant part in whether people continued to believe into adulthood, it found.

The research will refuel the controversy about the existence of a so-called God gene, which has been hotly disputed by clerics and theologians.

Based on an analysis of more than 500 identical and non-identical twins, the study at Minnesota University in America set out to discover whether spirituality was the result of nature or nurture.”
