African IQ levels so low as to make them useless in a modern technological society

Another letter to my English Member of Parliament

The following chart (The Evolution of Human Genetic and PhenotypicVariation 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. See link below:

"The Genetic Structure and History of Africans and African Americans" shows in the following chart how very different Europeans are from other subgroups.

Why is it British Government policy to allow the mass immigration of peoples who are genetically very different to the indigenous population, and who appear to have average IQ levels so low as to make them useless in a modern technological society?
Why is there surprise when immigrants with low IQ become dependent 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?
