If natural selection is defined as the accumulation or accentuation of a new trait that allows better survival or utilization of the environment that the organism lives in, then even though the african bee was introduced by us, its spread is controlled by natural selection. If it cannot incorporate genes, behaviors, that allow it to adapt to northern regions, then its expansion has been stopped or, at least slowed, by natural selection. If we as a species allowed our world to be controlled naturally, as many claim we should, natural selection would very rapidly change us back to a very primitive form, that those of us around now would find very intolerable.
