Not true. Ludi, you can't possibly be that ignorant of anthropology. Cro-Magnon was large-brained (more so than any modern race, volume >1500 cm^2), fair-skinned, native to Europe and northern Asia (where his remains are chiefly found). His skull and teeth are visibly caucasiod. His closest modern ethnic groups are the Finnish and the Lapps. His genes are present in reduced portion in East Asians and in Native Americans because in prehistoric times the Cro-Magnon was a wanderer who met and mated with the early Yoyoi Asiatic sapiens, producing the hybrid Asiatic who, in turn, formed a part of the gene flow across the Bering strait during the Ice Age.
I've not yet figured out whether you are joking or being seriously deceptive.

There's nothing theoretically wrong, as far as I know, with a dark-skinned human race having a large brain and a high average IQ. But in the real world I don't know of any such race.
Studies based on MRI scans show that the average brain volume for modern Whites is 1427 cubic centimeters; for African Blacks, 1361 cubic centimeters. US-resident Blacks (who have a bit of White in their genetic makeup) have brains of intermediate volume, with the variation being in proportion and in positive correlation with the degree of White admixture.
In terms of brain weight, the averages for mulatto brains went like this:
pure Black = 1,157 grams
15/16 Black, 1/16 White = 1,191 grams
7/8 Black, 1/8 White = 1,335 grams
3/4 Black, 1/4 White = 1,340 grams
1/2 Black, 1/2 White = 1,347 grams
For US-residents, the average Black brain is about 100 grams lighter than the average White brain. That 100-gram weight difference, between White Americans and US-resident Blacks, corresponds to an approximate 600 million neuron advantage for Whites. In 600 million neurons, there are about 600 billion synapses, each of which carries, as a minimum, one bit of cortical information.
IQ correlates very well with brain weight, with pure African Blacks having an average IQ of 70, with US-resident mulattoes having an average IQ of 85, and with Whites averaging at IQ 103. The standard deviation in IQ for US-resident Blacks is 12 points; that for Whites is 15 points.

it isn't about size, it's about how you use it (lol... this can be used in other contexts). your wisdom and ethics are non-existant, your brain is filled with crap, therefore you should not survive the die-off.
