By the way, I don't know if you have heard about these two papers before. They might interest you (or not). Hopkins, Russell, Schaeffer, "Chimpanzee Intelligence is Heritable", Current Biology, 2014. <way too many coauthors to list but the main guy seems to be P.M. Visscher>, "Genome-wide association studies establish that human intelligence is highly heritable and polygenic", Molecular Psychiatry, 2011. The latter paper reports on a study (with N=3511) on unrelated people to see whether their genotype and their phenotype regarding intelligence had anything to do with each other. People were tested with DNA chip for SNPs and had their IQ measured. The interesting result was that people who had more similar DNA also had more similar IQs (and vice versa, of course).
