...prayers were not answered. No less a scientist than Biologist Thomas Henry Huxley further espoused the idea in his 1863 Man's Place in Nature. Darwin won many new converts to his concept in 1871 with the publication of The Descent of Man. Most convincing of all, the fossil record continued to reveal that man had not always existed in his present form. That more primitive men might once have walked the earth was suggested when a skull was found at Gibraltar in 1848 that was more evolved than the skulls of apes but less so than that of modern...
...master clock and perhaps use that precious knowledge to slow it or even stop it. One locale for the clock (if there is indeed only one) may be within the smallest unit of life, the cell. Growing normal embryonic cells of various species in a test tube, Biologist Leonard Hayflick has made an astonishing finding: they are not immortal, as scientists believed from early experiments, in which a single cell line had been cultivated for years, but have definite life spans...
...most important reason that most geneticists and molecular biologists now oppose the legislation is a growing conviction, based on continued experiments, that current recombinant DNA research is safe. Some strains of E. coli normally reside in billions in the human intestine, a fact that encouraged the fear that new laboratory forms would spread like the plague among human beings. But research has shown that E. coli K12, which traces its ancestry to bacteria taken from a human patient at Stanford University in 1922, altered genetically during its life in the labs; among other changes, it can no longer colonize...
Some 20 years ago, British Biologist J.B.S. Haldane anticipated the gene-based view of sociobiology when, tongue in cheek, he announced that he would lay down his life for two brothers or eight cousins. His reasoning: the survival of two full siblings (each with about half of his genes identical to Haldane's) or the group of cousins (each with about one-eighth of his genes the same as Haldane's) made the decision genetically acceptable...
...British Biologist William Hamilton in 1964 explained how altruism could help an individual spread his genes; he argued that the principle explained the social life of insects...
