Then depending on what variation is best for survival, that ends up being your majority in the future generations.  Theoretically, you could use eugenics to make any country smart.  In fact people like (((Frank Luntz))) have taken advantage of the U.S.'s cherry picking of Nigerians to make it look like the average Nigerian is as good or better than the average american. Which is an obvious lie.
