What is the evidence that races are equal in intelligence?

I realize that this is a topic that gets peoples’ emotions running high, but I’m curious. I imagine that this thread will get moved pretty fast.

Anyway, my question is: What is the evidence that races are equal (in general) in intelligence?

Most of the information I have seen deals with evidence of inequality, and the possible refutation of such evidence.

What about positive evidence? For example, a study of adopted kids that show they have on average the same cognitive abilities, regardless of their race, would be evidence.

My question is – what such studies, etc., are there out there?

Now, I’m not asking who should have the burden of proof in the race and intelligence debate - that is a question for GD.

Also, I realize that some people believe that “race” does not exist, or that “intelligence” is a meaningless unmeasurable concept. I agree that for those people, my question is meaningless. So there’s no need to discuss these points in this thread.
