...stars. "It is not difficult," he explains, "if one is in no particular hurry." For flights that will last from decades to hundreds of years, he has worked out a method that will avoid dooming travelers to spend most of their lives in space. Simply send egg and sperm cells on the trip, he says, and have computers mate them some 20 years before the voyage is to end. After that, he suggests, "carry the embryos through to birth by techniques already foreshadowed in today's labs-and bring up the babies under the tutelage of cybernetic nurses...
...every man and woman to have 46 chromo somes per cell: 22 pairs of autosomes, which determine countless characteristics other than sex, and two gonosomes or sex chromosomes. In the female, these are a pair of Xs; in the male, an X and a Y (see diagram). When a sperm fertilizes an ovum, each supplies half the 46 chromosomes for the combination of cells that will grow into a baby. If the sperm contains an X chromosome, the baby gets that X plus one from the mother, and will be an XX girl. If the sperm contains a Y chromosome...
...Life Begins began, literally, with the birds and the bees, covered marine life and then the lower mammals (a spaniel bitch lovingly licking life into a pup emerging from her womb). With humans, the program called a sperm a sperm, and showed a natural birth at Manhattan's Flower and Fifth Avenue Hospitals. The mother's face, at first view contorted during her contractions, suddenly suffused with pleasure at the first cry of her child. ABC also edited in segments of the famed Swedish film on the growth of the fetus that had been shown the week before...
...often irretrievably destroyed months to years before the respiratory and vasomotor centers fail. At the same time one can share Schreiner's (1966, p. 100) disconent and insist that "a coordinating vital principle exists which is either there or not there." This vital principle comes into being when the sperm fertilizes the ovum and persists until life no longer is present. The moment of death can only be approximated...
Lilly undermines his accomplishments, and his book, with a stubborn allegiance to an unsubstantiated theory: that mammals with brains larger than man's are more intelligent than man. Without offering any scientific documentation, he suggests that the sperm whale, whose brain is six times as big as man's, could hear a symphony once, store it in his computerlike mind and play it back to himself note by note. Says Lilly wistfully: "I would like to exchange ideas with a sperm whale." The last fellow who dared to say that was Captain Ahab...
