Biological genetic evolution can only react and never foresee.
At some stage in human development; it does not much matter exactly when; the biological evolutionary ground work needed for the development of human language and culture had been completed, and since that day most of our growth and development has been of a technological form. Language and culture being themselves only technologies in the broadest sense of the word, and technology has created almost all that we have gained since then. Yet the truth is, religion and culture being derived from language technology are therefore two things that genetic evolution could never have foreseen, and because genetic development moves more slowly than technology, it will never catch up. We are therefore left as creatures who are almost totally undefended by our genetics against any attempt to reprograme us using language and text. Should we therefore be surprised, that people are happy to do things quite against their own and everyone's health in the name of religion and culture, or that we can do nothing about it.
That’s an intriguing hypothesis. It also makes perfect sense following your arguments through. Food for thought!
I haven't thoroughly studied the data but I've read that of all species that have existed on Earth, 99.9 percent are now extinct. Biological evolution tries a lot of things and the vast majority them don't end successfully. I'm starting to think our 'intelligence' trick may be headed that way.
Sorry for the nihilistic comment but to me recently it's appeared a discouraging time for our species.
Update: That comment is too negative. We need to redouble our efforts (they are there) to take better control of our destiny while we can.
Your comment really needs a well thought out reply and I will get back to you if I can think of more. But I will say, for now, that one of the most interesting new things that will happen in the near future, is going to be the new technology of genetic engineering, and our power to design babies. It will happen whether we like it or not, because you can never keep the technology cat in the bag however much you want to. But if it goes well then it could save us from the slow decline that modern civilizations sellective preasures will force on to us. The glib, "To be a genetic successful breeder means being too stupid to understand how contraceptives work, and that makes stupid the future" will have to do for now as an example. But I would imagine that many will value intelligence in their own children, especially irronically many anti-intellectuals. (It is different when they are your children.)
