...investment in South Africa. Harvard does not realize that what is crucial about American companies in South Africa is not so much how they treat their employees, but what they produce, import and invest in. What is crucial is the moral and political support they lend to that fossil of historic the most racist country on the face of this earth, South Africa...
...oilmen, they mean hefty savings in exploration costs, since fern fossils will indicate at what depths oil is likely to be found. Fern spores, very common in fossil records, are used to date the age of rocks below the earth's surface. Since scientists know that rocks of a certain age-or depth-are more likely to contain oil than others, fern-spore dating can help them decide whether to drill deeper to find...
...find initially seemed unimpressive. Kamoya Kimeu, head of Anthropologist Richard Leakey's proficient fossil collecting team, last summer discovered a hominid skull fragment that was 1½ in. square on a rocky slope above northwest Kenya's Nariokotome River. But over a month's time, the expedition crew, under the joint leadership of Leakey, director of the National Museums of Kenya, and Alan Walker, professor of cell biology and anatomy at the Johns Hopkins University medical school, began to turn up other whisky-colored skeletal pieces in the nearby sandy debris: first a rib, then a scapula...
...justification for this new idea came from a series of startling geological studies in the late 1970s by two University of Chicago geologists. David Raup and John Sepkowski. By carefully analyzing fossil records of the evolution of marine animals, the two concluded that large-scale extinctions occur about every 26 million years...
...Berkeley team's principle researchers. They reasoned that iridium-rich asteroids bombarded the earth, kicking up so much terrestrial and asteroidal debris into the atmosphere that it blocked sunlight from the earth for as long as several months. As temperatures plummeted, plants and animals died, leaving the current fossil record...
