In the comments below on the post on human population structure there was some request for a bigger global perspective. Below the fold I've placed a table with FST values which compare each population to the other. This an older population genetic statistic derived from the work of Sewall Wright, but you are almost certainly familiar with the talking point that "85% of variation is within races, and only 15% between." That is an FST insight. The higher the FST the greater the proportion of genetic variation which can be attributed to between population differences, so it serves as a rough measure of genetic distance. But it needs to be used carefully; population genetics has many numbers, but that shouldn't lead to accept the illusion that it is like measuring the velocity of a falling ball.
