From 100 years ago, Scientific American calls for more research into human evolution:
Mendelian principles have no doubt long been followed by professional animal breeders in an empirical way, but only within recent years have enough data been accumulated to show that they apply with equal force to human beings. We know enough about the laws of heredity, we have enough statistics from insane asylums and prisons, we have enough genealogies, to show that, although we may not be able directly to improve the human race as we improve the breed of guinea pigs, rabbits or cows, because of the rebellious spirit of mankind, yet the time has come when the lawmaker should join hands with the scientist, and at least check the propagation of the unfit. Prizes have been offered to crack trotters for beating their own record, $10,000 for a fifth of a second, all for the purpose of evolving a precious two-minute horse. Yet we hear of no prizes which are offered for that much worthier object, the physically and intellectually perfect man.
