RE: In Gods We Trust (The Evolutionary Landscape of Religion)
Having grown up without religion and in a secular environment, believing in a god has always been a completely alien concept. That also made religion, so ubiquitous in the world, a very interesting phenomenon to me.
A few thoughts:
Religiosity is evolutionarily adaptive.
While religious belief indeed builds on mental faculties that evolved for other reasons, e.g. pattern recognition and theory of mind, it has become so widespread because it does increase reproductive fitness. And this must be true, since religious practices are very costly through behavioral and material practices, like those before-mentioned sacrifices and eating restrictions.
The biggest indication of religion being an evolutionary strategy is its obsession with sex. Many of the regulations in successful faiths target sexual behavior. Men should have vaginal intercourse with women. You should not masturbate. You should not practice homosexuality. You should not use birth-control methods. And which relationship forms are acceptable? Exclusive monogamy is. One man should be with one woman, and cheating is forbidden.
Religious sexual mores thus increase fertility and social stability.
Such religions will thus grow in numbers. It will yield relatively stable societies where women bear numerous children and men are invested to work hard and protect their community. Sex is the most powerful motivator, and masturbation, homosexuality and birth-control relieve this urge without reproductive value. If this is not constrained, the birth rate will plummet significantly and this is exactly what we see happening in the Western world.
If there was an powerful, universe-creating god, do you really think he would concern 'himself' with human things like jacking off? But the idea of people believing in a personal god does make sense when you realize that groups of people that acquired these believes started breeding like rabbits. There's a reason that the gods of Christianity and Islam will punish people for transgressions in an afterlife, and also require punishment in this world. This protects the community from free-riders.
Religion is why monogamy is both unnatural and common.
Men often cheat, mostly for variety and siring more offspring. Women often cheat, mostly for obtaining better genes. Monogamy is not common in the natural world and it isn't easy for humans. The reason why most people live in monogamous cultures, is that the groups that enforced it (via religion) grew the biggest.
No monogamy means conflict between males. Competition for females quickly turns violent and is very costly, wasting resources that are better spent on other endeavors. In places where parental investment is less important because of resource abundance, the lack of monogamy results in a lack of fathers working hard towards progress. In other words, monogamy results in many babies and men that work hard.
Even though I am not religious, I have to admit that the technological superiority of the West stems from sexually-restrained, monogamous, religious communities. Why this happened in Europe and not in the Middle East is the topic for another time.
Modernity destroys religion, except when religions are protected by modernity.
Population growth is important and increased by religion. However, scientific progress of a populations confers power relative to primitive populations. Small groups with technology, e.g. weapons and medicine, can easily dominate more numerous competitors. That's what we've seen in the past. And the same scientific insights in the way the world works that are necessary for advanced weapon systems, also erode religious beliefs. Hurricanes and thunder storms aren't angry deities and the world isn't created by divine intervention. These insights contradict religious texts and either result in secularization or mental gymnastics about how it was meant as a metaphor. Or young earth delusions.
So while religion first increased reproductive success, a strict adherence will be a negative against societies that welcome science and technology. Your exponential growth potential means nothing when enslaved or exterminated by enemy populations. But this is not what we see happening.
A group like the Amish can stay fundamentalist and prosper, because they are protected by a host country that bears the evolutionary cost of secularization and technological advance.
In the same way, radical Islam remains competitive because they can use the benefits of modern society (e.g. automatic weapons, missiles and propaganda Youtube productions) without restricting their religious social and sexual paradigm. Without access to our inventions there would be no threat.
Similarly, they can exploit our liberal institutions to expand and dominate. Using our pathologically altruistic laws and policies, they can invade and colonize our territories and breed children on our reserves. The only reason we have all these resources and institutions is because everyone was restricted for the good of the whole. They can extract all the juice while giving nothing back.
Closed systems prevent this exploitation.
If our societies weren't so suicidal and exploitable this wouldn't be possible. Closed borders means separate systems, and then a system would either also have to progress and develop means to gain knowledge (i.e. science) or become absolutely powerless to defend themselves.
