Genetics and intelligence

The following chart (The Evolution of Human Genetic and Phenotypic Variation in Africa Michael C. Campbell1 and Sarah A. Tishkoff1,2) shows how the different genetic groups of humans in Africa split from each other up to 150 thousand years ago and developed in isolation from each other. Further, the group which was already separately developed and emerged from Africa 100 thousand years ago has again further developed separately.

Why is there surprise when immigrants with low IQ become dependant on the state and riot when discontented with their lot? Why aren't the British people made aware of these facts before throwing away 150 thousand years of separate genetic development? What steps are being taken by the Government to remedy the situation?
