You must be talking about
THIS TIME ARTICLE, which unfortunately only offers the first paragraph, however, I did find
THIS which again isn't the entire article, but is much deeper.
The article basically explores a recently published book The God Gene: How Faith Is Hardwired into Our Genes by molecular biologist Dean Hamer. Hamer claims that human spirituality is an adaptive trait, and also says he has located one of the genes responsible, a gene that just happens to also code for production of the neurotransmitters that regulate our moods.
Our most profound feelings of spirituality, according to a literal reading of Hamer’s work, may be due to little more than an occasional shot of intoxicating brain chemicals governed by our dna. “I’m a believer that every thought we think and every feeling we feel is the result of activity in the brain,” Hamer says. “I think we follow the basic law of nature, which is that we’re a bunch of chemical reactions running around in a bag.”
Hamer also states, “My findings are agnostic on the existence of God,” he says. “If there’s a God, there’s a God. Just knowing what brain chemicals are involved in acknowledging that is not going to change the fact.”
Interesting article, no doubt. However, one question still is not answered. How do you explain people who were atheist and then later in life believe in god or vice versa?
