The gene often referred to as the "god gene" is the VMAT2 gene (vesicular monoamine transporter 2).
Dean Hamer proposed the existence of a "god gene" in his book, "The God Gene: How Faith is Hardwired into Our Genes." Hamer's research suggested that variations in the VMAT2 gene are correlated with spirituality. He posited that this gene influences monoamine levels in the brain, which in turn affects experiences associated with spirituality and religiosity, such as self-transcendence.
It's important to note that the concept of a single "god gene" is highly debated within the scientific community. The relationship between genetics and complex human traits like spirituality is likely far more complicated than a single gene determining one's openness to spiritual experiences. Many genes, environmental factors, and personal experiences likely contribute to an individual's spiritual inclinations. While the VMAT2 gene may play a role, it's not the sole determinant.
Here's a breakdown of the key points:
- VMAT2: The gene in question, responsible for transporting monoamines (like serotonin, dopamine, and norepinephrine) in the brain.
- Dean Hamer's Hypothesis: Variations in VMAT2 may influence levels of monoamines, affecting spiritual experiences.
- Complexity of Spirituality: The genetic basis of spirituality is complex and likely involves multiple genes and environmental factors.
- Controversy: The "god gene" concept remains controversial within the scientific community.
In conclusion, while the VMAT2 gene is often referred to as the "god gene" due to Dean Hamer's research suggesting a link between variations in this gene and spirituality, it's crucial to understand that spirituality is a complex trait influenced by many factors, and attributing it to a single gene is a simplification.
