...cultural deprivation of blacks and the cultural bias of I.Q. tests. Because Herrnstein accepts Jensen's ideas about heredity and intelligence, as well as Jensen's contention that compensatory education has failed, he is likely to be criticized by some scientists who, like Nobel Geneticist Joshua Lederberg, have already labeled Jensen's findings "premature" and "inconclusive...
...Fully 25% of all conceptions fail to reach an age at which they can survive outside the womb, and of these, at least a third have identifiable chromosomal abnormalities. Still, as many as five out of every 100 babies born have some genetic defect, and Nobel-Prizewinning Geneticist Joshua Lederberg believes the proportion would be even higher were it not for nature's own process of quality control...
...capacity." For example, it is believed that genetic influence is especially great in such areas as mathematics, music and maybe acrobatics. Unless genetic potential is tapped by the environment, it will not develop: kittens prevented from walking will not learn normal form and depth perception. Says Geneticist Joshua Lederberg: "There is no gene that can ensure the ideal development of a child's brain without reference to tender care and inspired teaching...
...RING IS ONE among many, both scientists and ethicists, who find it considerably harder to justify "positive" genetic engineering, restructuring the genes to make the "perfect" man. The prospect suggests apocalyptic possibilities: M.I.T. Biologist Salvador Luria approaches it "with tremendous fear of its potential dangers." Biologist Joshua Lederberg of Stanford University disowns such Utopian aims as a proper goal for serious biology, and even doubts that techniques sophisticated enough to achieve them could be perfected in the near future. But the possibility nonetheless tantalizes: Who would decide what qualities to preserve, and by what standards? Even remedial genetic engineering could...
...entire U. S. population is exposed to the level the AEC considers safe for the general population, Joshua Lederberg, Nobel Laureate in genetics, estimates a 10 per cent increase in the mutation rate. Other researchers, notably Drs. Gofman and Tamplin of the AEC, estimate between 32,000 and 150,000 additional annual deaths due to increased mutation, cancer and leukemia...
