I think that intelligence matters in contemporary evolution as well, it might decrease the chances of individuals doing outright stupid things which could lead to death at young age. It's not random which youth that dies in traffic accidents due to taking unnecessary risks, and this could have to do with genetics.
Whoops, I'd forgotten that i had posted here. Started quite a discussion...

Anyway, I had about the same argument as that of Moros in mind. Even though there is a random element; doesn't evolution still tend to be very 'deterministic'? The advantage that higher intelligence (however we define that) gives will need to be very significant in order for it to become an evolutionary factor. If not, it will simply stay on an individual level. And, as I said earlier, since different enviroments probably didn't require different "levels" of intelligence, all "races" are most likely similar in this area.
