...proponents of the new theory themselves admit, it is still only theory. They are not working with fossil teeth and jaws but with habits and customs that naturally left no physical trace. All that they have guessed about man's biological history remains to be proved. But the guesses carry many implications. Perhaps the most significant is that civilization's splendid institutions owe a part of their balance to the wily jungle primate still surviving beneath man's cultural veneer. He is really a part of the design. His contribution, only just beginning to be perceived...
...Harvard undergraduates, Frank Sulloway '69, explained recently that the film will examine the influence of South America on Darwin's theory of evolution in terms of people, places, flora, fauna, geological formations and fossil deposits...
...estimated 90% of Americans will live in urban areas and drive perhaps twice as many cars as they do now. The hope is that Detroit will have long since designed exhaust-free electric or steam motors. Another hope is nuclear power to generate electricity in place of smoggy "fossil fuels" (oil, coal), but even with 50% nuclear power, U.S. energy needs will so increase by 2000 that fossil-fuel use may quadruple. Moreover, nuclear plants emit pollution: not only radioactive wastes, which must be buried, but also extremely hot water that has to go somewhere and can become a serious...
...seems undeniable that some disaster may be lurking in all this, but laymen hardly know which scientist to believe. As a result of fossil-fuel burning, for example, carbon dioxide in the atmosphere has risen about 14% since 1860. According to Ecologist Lamont C. Cole, man is thus reducing the rate of oxygen regeneration, and Cole envisions a crisis in which the amount of oxygen on earth might disastrously decline. Other scientists fret that rising carbon dioxide will prevent heat from escaping into space. They foresee a hotter earth that could melt the polar icecaps, raise oceans as much...
Asked by the Ohio State scientists to identify the 2½-in.-long fossil, Paleontologist Edwin Colbert, of the American Museum of Natural History, last week announced that it was a bit of jaw bone from a 3 to 4 ft. salamander-like creature that lived about 200 million years ago in the early Triassic period. It was the first evidence that land vertebrates had roamed Antarctica when its climate was warm...
