It's actually genetics, not culture. Our last common ancestor was 50,000 years ago, and we know that the rate of brain evolution increased 100 fold in populations outside of Africa due to the discovery of agriculture, starting around 10,000 years ago. We are nothing more than talking apes, subject to the same types of evolutionary force every other creature on this planet is. There is no such thing as magic dirt, culture is a reflection of genetics (not an overlay on top of it), and you are not a "blank slate" when you are born.
