Is it a gay gene or a God gene

Dr. Dean Hamer, a molecular geneticist, once claimed that he discovered a gay gene. Further research by others shot down that theory. Now he claims that he has found a God gene.

Still, he writes, the fact that spirituality has a genetic component implies that it has evolved for a purpose. "There is now reasonable evidence that spirituality is in fact beneficial to our physical as well as mental health. Faith may not only make people feel better, it may actually make them better people."

This sort of goofy genetic determinism used to be very politically incorrect.
