...NATIONAL GEOGRAPHIC SOCIETY SPECIAL (CBS, 7:30-8:30 p.m.). More on evolution. "Dr. Leakey and the Dawn of Man" deals with Anthropologist Dr. Louis Leakey and his family of fossil hunters in East Africa. After more than 30 years, the Leakeys have made such finds as Zinjanthropus, a manlike creature believed to have lived 1,750,000 years ago, and the 2,000,000-year-old Homo habilis, who was found among some of the earliest signs of "culture," and is believed to be a direct ancestor of modern...
Kick from Fossils. Despite atomic inroads, the fossil fuels have a lot of kick left. Battling to save the market they have long dominated, coalmen have turned to unit trains, automated mining equipment, and mine-mouth generating plants transmitting power across huge distances via super-high-voltage lines. Nuclear plants remain too costly for small utility companies or sparsely populated regions. In such Southwestern states as Texas, utility men insist that they will rely on cheap natural gas for years. With the total U.S. demand for electricity doubling every decade, even General Electric figures that coal consumption in U.S. power...
Analysis of the slices, Heezen reported to an oceanographic conference at Moscow University, showed that the most recent magnetic-field reversal occurred about 700,000 years ago, following earlier flips 2,500,000 and 3,500,000 years ago. Fossil remnants in the slices also indicated that several new species of algae and protozoa suddenly appeared about 2,500,000 years ago and existed without significant change until 700,000 years ago. Then, within a short time span, some of those species completely disappeared, others underwent marked change, and new species emerged...
Although all fossil collecting is under control of the Argentinian government, the provincial governor of La Rioja defied the law and issued a personal decree forbidding the removal of any fossils from La Rioja. He was responding to a "they're robbing the province of its natural heritage" campaign which began when the value of the expedition's find became known...
