...Your story, "The Dilemmas of Power" [Aug. 29], contains a garbled paragraph that is misleading and embarrassing to me and my company. Observations about the alleged harmful effects of fossil-fuel burning on public health appear" to be erroneously attributed to me. You should correct the record...
...happens, new fossil finds made by other investigators, operating quite independently, are closing the gap by showing that Australopithecus is really much older than had been thought-in fact, as much as 6,000,000 years...
Ferocious Neighbors. The evidence comes, in part, from Africa's Omo River Basin, a fossil-rich area where the borders of Ethiopia, Kenya and the Sudan meet. There, a University of Chicago expedition has found 40 prehistoric teeth and two jawbones buried in volcanic ash that is perhaps 4,000,000 years old. The expedition's leader, Anthropologist F. Clark Howell, is convinced that the creatures are members of the Australopithecus family, even though they must have belonged to a branch that probably did not eat meat or make tools. Despite their proximity to various ferocious neighbors...
...discoverers have not yet acknowledged their finds in formal reports to scientific journals, perhaps because the bones upset too many old theories. Their scientific caution is understandable. In a few short years, man's fossil record has been extended from less than 2,000,000 years to possibly more than 14 million. Yet even that startling leap back into the past amounts to only a few moments in the 4.5 billion-year history of the earth. Three billion years before man's ancestors took their separate evolutionary path from the apes, life already existed and flourished. Despite...
While the geologists, chemists and physicists are busy with their investigations, other scientists will be on an even more exciting quest. Biochemists will be examining the specimens for evidence of amino acids and protein molecules?the building blocks of life. Paleontologists will seek fossil remnants of organisms. At NASA's Ames Research Center at Moffett Field, Calif., still other investigators will try to coax life itself from the lunar rocks, using nutrients in the hope of resuming a life process that might have been interrupted millions of years...
