Hybridization Hybridization of superior and dissimilar stocks is the secret of the creation of new and more vigorous strains. And this is true of plants, animals, and the human species. Hybridization augments vigor and increases fertility. Race mixtures of the average or superior strata of various peoples greatly increase creative potential, as is shown in the present population of the United States of North America. By now, on a normal planet the races are practically blended, so that it can be truly proclaimed that God has made of one blood all the nations. 82:6.5 https://mm.spiritualfamily.net/Urantia_Book-Online_Reader-2019/Paper_082.html#82:6.5
