You can validly support the genetic basis for cognitive advantage without understanding the precise functioning of the brain, because the brain is a physical structure. Being complex its unlikely a single genetic factor (nor is intelligence singular anyways) determines it. But there is a substantial amount of evidence that supports at least some genetic basis for traits that give some people a cognitive advantage over others, inline with the genetic influence for all other physical traits.

Ok, so you are admitting your ideas are fact-less, mere assumptions that can easily be true or false, yet you're down voting my comment because it doesn't align with your evidence-less assumptions about the brain?
Again, what's that evidence? Is it a genome? some sort of better brain capacity?

I'm saying that were there a dearth of evidence either way, the argument for a genetic basis would still be valid based on the premise that the brain is a physical structure (among other things). In actuality, there's a good bit of evidence that its at least partially, and perhaps mostly, genetic.

Its polygenetic and at least partially influenced by the environment. Its unlikely that higher brain capacity plays a large role (in the difference between humans). Identical twins separated at birth provide the best evidence

Wasn't me :)
