Intelligence doesn't grant immunity to changes in natural conditions.


Not immunity but it sure helps if I put my coat on before I go outside to conditions that would kill me in an hour or less without it.

The only way natural selection can work to allow a species to adapt to changing natural conditions is if individuals exhibiting random variations either live to breed or die before they are able to breed, weeding out those without the variation that allows them to adapt to changing conditions. Instead, with intelligence, what we have is evolving technology responding to changes in natural conditions.

Perhaps considering that so many smart people choose stupid ones with which to mate, there might be an instinctual drive to re-introduce evolution back into the gene pool.

Are not error and culture a field addititive to "the arbitrary application of natural conditions"?

Natural selection has stopped in intelligent species. It is replaced by a thoroughly random process or error and culture where, in contrast, natural selection has a "vector" governed by an almost fixed environment.

There is still the arbitrary application of unintended consequences.

Just another fully randomizing process.

<For example, does democracy affect the switching on and off of some genes during embryonic development?

I would argue that democracy causes devolution.

Are resulting somatic and intellectual changes heritable?

Intellectual changes, growing size of grey matter, are not elements of evolution under natural selection.

Intelligence doesn't grant immunity to changes in natural conditions.
You don't use "natural" the way Darwin does. Natural doesn't mean "intelligently designed".

The arbitrary application of natural conditions to intelligent species will be the subject of scientific enquiry soon.

Never. Contradiction in terms.

We're going off planet and I suspect human evolution there will accelerate.

Has no effect on evolution because for intelligence species, Darwinian evolution has stopped. Improvement, growth, expansion, are not necessarily attributes of evolution. Many species alive today have hardly changed in 500 million years, crabs for example.

- it's a very dangerous niche.

No more dangerous than it is now.
