hybridization

82:6.5Hy­bridiza­tion 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. When such mat­ings take place be­tween the lower or in­fe­rior strata, cre­ativ­ity is di­min­ished, as is shown by the pres­ent-day peo­ples of south­ern In­dia.

82:6.6Race blend­ing greatly con­tributes to the sud­den ap­pear­ance of new char­ac­ter­is­tics, and if such hy­bridiza­tion is the union of su­pe­rior strains, then these new char­ac­ter­is­tics will also be su­pe­rior traits.

82:6.7As long as pres­ent-day races are so over­loaded with in­fe­rior and de­gen­er­ate strains, race in­ter­min­gling on a large scale would be most detri­men­tal, but most of the ob­jec­tions to such ex­per­i­ments rest on so­cial and cul­tural prej­u­dices rather than on bi­o­log­i­cal con­sid­er­a­tions. Even among in­fe­rior stocks, hy­brids of­ten are an im­prove­ment on their an­ces­tors. Hy­bridiza­tion makes for species im­prove­ment be­cause of the role of the dom­i­nant genes. Racial in­ter­mix­ture in­creases the like­li­hood of a larger num­ber of the de­sir­able dom­i­nants be­ing pres­ent in the hy­brid.

82:6.8For the past hun­dred years more racial hy­bridiza­tion has been tak­ing place on Uran­tia than has oc­curred in thou­sands of years. The dan­ger of gross dishar­monies as a re­sult of cross­breed­ing of hu­man stocks has been greatly ex­ag­ger­ated. The chief trou­bles of “half-breeds” are due to so­cial prej­u­dices.

82:6.9The Pit­cairn ex­per­i­ment of blend­ing the white and Poly­ne­sian races turned out fairly well be­cause the white men and the Poly­ne­sian women were of fairly good racial strains. In­ter­breed­ing be­tween the high­est types of the white, red, and yel­low races would im­me­di­ately bring into ex­is­tence many new and bi­o­log­i­cally ef­fec­tive char­ac­ter­is­tics. These three peo­ples be­long to the pri­mary San­gik races. Mix­tures of the white and black races are not so de­sir­able in their im­me­di­ate re­sults, nei­ther are such mu­latto off­spring so ob­jec­tion­able as so­cial and racial prej­u­dice would seek to make them ap­pear. Phys­i­cally, such white-black hy­brids are ex­cel­lent spec­i­mens of hu­man­ity, not­with­stand­ing their slight in­fe­ri­or­ity in some other re­spects.

82:6.10When a pri­mary San­gik race amal­ga­mates with a sec­ondary San­gik race, the lat­ter is con­sid­er­ably im­proved at the ex­pense of the for­mer. And on a small scale—ex­tend­ing over long pe­ri­ods of time—there can be lit­tle se­ri­ous ob­jec­tion to such a sac­ri­fi­cial con­tri­bu­tion by the pri­mary races to the bet­ter­ment of the sec­ondary groups. Bi­o­log­i­cally con­sid­ered, the sec­ondary San­giks were in some re­spects su­pe­rior to the pri­mary races.

82:6.11Af­ter all, the real jeop­ardy of the hu­man species is to be found in the un­re­strained mul­ti­pli­ca­tion of the in­fe­rior and de­gen­er­ate strains of the var­i­ous civ­i­lized peo­ples rather than in any sup­posed dan­ger of their racial in­ter­breed­ing.

64:6.322. Stronger and bet­ter races are to be had from the in­ter­breed­ing of di­verse peo­ples when these dif­fer­ent races are car­ri­ers of su­pe­rior in­her­i­tance fac­tors. And the Uran­tia races would have ben­e­fited by such an early amal­ga­ma­tion pro­vided such a con­joint peo­ple could have been sub­se­quently ef­fec­tively up­stepped by a thor­ough­go­ing ad­mix­ture with the su­pe­rior Adamic stock. The at­tempt to ex­e­cute such an ex­per­i­ment on Uran­tia un­der pres­ent racial con­di­tions would be highly dis­as­trous.
