genes and genealogy

Christopher Jones is in need of professional counseling as to what career he should choose: "My thanks to Martin Lewis for his recommendation of Luigi Cavalli Sforza's book. But I don't know what to make of this news: on one hand, if I have buried deep inside me an earthworm gene, should I have chosen to be miner? On the other, if I am distantly related to a Xhosa tribesman, could I potentially cultivate that gene to better hunt rhinoceros -- but wouldn't that constitute cannibalism of a distant relative?"
