...Gene Is religion part of nature's evolutionary scheme? Scientists are asking whether spirituality might be embedded in our DNA...
...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...
...smoking survey to conduct a little spirituality study on the side. First he ranked the participants along Cloninger's self-transcendence scale, placing them on a continuum from least to most spiritually inclined. Then he went poking around in their genes to see if he could find the DNA responsible for the differences. Spelunking in the human genome is not easy, what with 35,000 genes consisting of 3.2 billion chemical bases. To narrow the field, Hamer confined his work to nine specific genes known to play major roles in the production of monoamines--brain chemicals, including serotonin, norepinephrine...
Studying the nine candidate genes in DNA samples provided by his subjects, Hamer quickly hit the genetic jackpot. A variation in a gene known as VMAT2--for vesicular monoamine transporter--seemed to be directly related to how the volunteers scored on the self-transcendence test. Those with the nucleic acid cytosine in one particular spot on the gene ranked high. Those with the nucleic acid adenine in the same spot ranked lower. "A single change in a single base in the middle of the gene seemed directly related to the ability to feel self-transcendence," Hamer says. Merely having that...
...fraternal twins that had been separated at birth and raised apart. The scientists were looking for traits the members of each pair had in common, guessing that the characteristics shared more frequently by identical twins than by fraternal twins would be genetically based, since identical twins carry matching DNA, and those traits for which there was no disparity between the identicals and fraternals would be more environmentally influenced...
