Sorry, what is the evidence that there is a genetic component to intelligence?

  All of it. I'm not quite sure what you're asking here. I feel that you and I must have drastically different starting assumptions, because your question seems meaningless in my context. Do you dispute that Homo sapiens has a higher intelligence than H. erectus did? Than other primates? Or are you alleging that the genetic basis for that intelligence difference shows no variation across human populations? I feel like I have to stretch what you said to give it a charitable interpretation, but here goes: are you asking whether there's any evidence that the genetic component's variation across human populations contributes to significant phenotypic variation when compared to environmental factors?
