Anatomically modern humans have been around for 2.5 million years. Behaviorally modern humans only about 200k. Initially this was assumed to be evidence of a simple gene that created a breakthrough to language, culture, etc. Continuing archeological evidence is now strongly slanted against that, particularly evidence from microlithic industries. It now appears far more likely that behavioral modernity emerged organically as a primitive social complex. Different locations independently discovered different pieces of the "toolkit" but it wasn't until the full kit of critical tools came together that we have the breakthrough to complex societies. Basically, your perspective on IQ and heritability is very cartoonish. I'd suggest spending some time on wikipedia. I'd also familiarize yourself with the classic rebuttal of The Bell Curve, which clarifies the difference between heritability and genetic determinism. Culture and social complexes are heritable.
