There's two ways this can go I think, either :-
1. You can look at intelligence as nothing more than an evolutionary adaptation to the environment; no more or less special than a rhino's horn. In which case changes to the environment can render our adaptation obsolete; just because we are clever, doesn't mean to say we won't get out-evolved if our environment changes. This means evolution will still be a pressure, and can shape our genes.
2. The theory of evolution does not and can never fully accomodate intelligence. With suffiecently advanced intelligence, it is possible that the world external to the human individuals never affects their genes. By which I mean the intelligence is able to keep the environment constant, and as such remove all evolutionary pressures.
If you believe intelligence cannot remove all evolutionary pressures, you are left in position one above, if you believe it can, you are left with position two.
As yet we are not, perhaps, 'intelligent' enough to counter all the effects the environment may have on our genes, and we do not have a long enough
perspective on our technology; the point is still, perhaps,
moot.
