Why did whites and Asians become advanced before blacks?

Please don't give me the standard liberal lecture of how Africa had tribes that fought each other leaving little time for inventions. The same was true for Europe and Asia, yet these regions became advanced and used a high level of technology well before blacks ever did. Is this a matter of race and IQ???... show more Please don't give me the standard liberal lecture of how Africa had tribes that fought each other leaving little time for inventions.

Please don't call me a racist either, I have no bias for any race, this is just a question that has bothered me for some time.
