It seems as if religious genes have been identified. You make of this what you will; Im just passing it along. I must say, though, that I love seeing scientists confused.
Genes may help determine how religious a person is, suggests a new study of US twins. And the effects of a religious upbringing may fade with time.
Until about 25 years ago, scientists assumed that religious behaviour was simply the product of a persons socialisation - or "nurture". But more recent studies, including those on adult twins who were raised apart, suggest genes contribute about 40% of the variability in a persons religiousness.
Now, researchers led by Laura Koenig, a psychology graduate student at the University of Minnesota in Minneapolis, US, have tried to tease apart how the effects of nature and nurture vary with time. Their study suggests that as adolescents grow into adults, genetic factors become more important in determining how religious a person is, while environmental factors wane.
