Evolution Debate

Are Asians/whites more evolved?

It's called evolution by race. Most features you described as pure white, asian, and black hold truth. There are minor variations but generally correct. Rushton and Jensen's research adds validity to your rather vast assumption. The IQ test from 2005 to 2010 between white and black revealed: whites on average have 15-18 higher score then blacks and whites have 80-85% likely to have higher IQ then blacks. Rushton also measured the size of average size of brain by race: whites 1347, blacks 1267, Asian 1364 For the correlation between brain size and intelligence, Pennington and Peper's research explains in detail. Their experiment results: brain size/ general intelligence = .41, brain size/ IQ = .24 based on meta analysis. They've also measured the heritability of brain size using global brain measure. The result show 0.82/0.88 = heritabily to of gray/white matter. The overall genetic correlation was 0.48. Based on the research, brain size is affected by genetics (race) and brain size reasonably correlate to intelligence. This hypothesis have yet to be disproved.  (Sep 30, 2013 | post #1349)
