Are you trolling? No. Animal breeds are pure, because their reproduction is controlled and only the desired stock is used. "Races" aren't like that at all. Saying something like "blacks have low IQ" is completely unscientific because the people you are labelling "black", unlike animal breeds have little to no genetic relation. I'm too lazy to look this up, but the median "african american" has less than half of their ancestry from subsaharan africa.

So please, don't say things like "race is genetically determined". You're right that a "genetic cluster" or "ancestral group" is better defined. But those IQ results weren't corrected for that, so again: non-science.
