Your post his one huge contradiction. I think you're confusing genetic adaptation (at a molecular level) with intelligence adaptation. You say that environmental adaptations aren't passed down through the genome and you are completely incorrect. That is exactly what defines genetic adaptation and gene mutation.
For example: A man has no clothes. He learns that he can use animal fur to keep himself warm. He passes this down to his children, and their children's children. That would be the passing of knowledge, not genetics.
On the other hand, a man is cold and doesn't quite figure out how to use animal furs to warm up. His body starts to produce more hair, speeds up his metabolism to produce more internal heat, and grows thicker hair. This is genetic adaptation and is certainly passed down through generations in the form of DNA...it becomes a part of his genome. If it wasn't passed down, everyone in the world would look the same.
A black man's genetic make up is different that white persons because of those adaptations. Their bodies adapted to become uber-efficient, using the best of the little they received. They processed nutrients more efficiently in the areas they most needed them (muscular structure, bone density, lung capacity, etc).
