Länk - Hawks citerar Dobzhansky (antropologi)

Neither do I need to retell here the story of the alleged relaxation or suspension of natural selection in civilized mankind. The dangers from this source, although not necessarily exaggerated, have often been presented in a wrong perspective. A notion, which is less frequently stated explicitly than implied in many writings, is that the progress of mankind would be safe and even irresistible if only the natural selection were permitted to operate unobstructed by civilization and its amenities. This notion does not stand critical examination. Natural selection does not even insure that the species on which it acts will survive, let alone that it will improve, in any sense of the word "improvement." Dinosaurs became extinct, despite their evolution having been piloted by natural selection, quite unhampered by culture, medicine, or charity (Dobzhansky 1963:148).
