Sexual dimorphism differences across races? I've read that sexual dimorphism is positively correlated with polygyny and less paternal investment, so I looked to see if this might be true across human races that are known to differ on these things. Wikipedia lists height studies from all around the world, so I calculated the percent differences in height between males and females for all available black and Asian samples. The results:
American blacks 8.41%
South Korea 8.13
Male-female differences are consistently smaller for Asian groups than for blacks, but not by much, so interpret as you will.
