A new study suggest that atheism and liberalism are perspectives, concepts, ideals (whatever word you want to use) that are not biologically designed.
In other words, our first human ancestors were very conservative by nature, caring about their immediate family while being indifferent or non caring to others.
I kind of think that hunters can't really be the most empathetic people on this planet, whether hunting for food or sport.
All humans have an innate raw intelligence, but it seems that there are some that have an enhanced intelligence.
Let me take a stab at it. The ability to look at things from all sorts of perspectives without doing so consciously. The ability to fathom many possibilities with a worldview dependent on evidence and what is probable.
The study says that humans are naturally paranoid, and this is why religion was a natural fit.
I say that it if I saw lightning, and I couldn't explain it scientifically, as our ancestors couldn't, I too would need to believe in a supernatural entity as being the cause. It was the only thing that made sense back then. Once you have explanations for the unknown, then you can be focused enough to hunt, eat, survive, procreate, and take care of the newer generation.
Things have changed now. We have scientific explanations. Those who have special intelligence tend to get that there is really no evidence or need for a God, that homosexuality is not a choice, that other human beings have feelings regardless of whether you know them or not, and that teaching fairy tales in science class is absurd.
