What do Osama bin Laden, Madonna and Karol Wojtyla all have in common? Aside from a fondness for unusual hats, that is. Stumped? Well, according to US geneticist Dr Dean Hamer, they are all likely to share the gene VMAT2. They’re all religious. They all believe in God. Dr Hamer calls VMAT2 the “God gene”. Apparently, he claims to have discovered that “the greater a person’s ability to believe in a greater spiritual force”, the more likely they are to have this particular gene glued to a banister, somewhere on the spiral staircase of their DNA.
