Patiently examining dozens of tiny tektites taken from the ocean floor off the Ivory Coast, Physicists Saeed A. Durrani and Hameed A. Khan found a striking correlation: large numbers of tektites had drifted to the sea bottom at about the same time that the earth's magnetic field is known to have had one of its reversals, some 900,000 years ago. Checking with other research, they found that another major concentration of these microtektites had settled around Australasia during another reversal that took place 700,000 years...
Such reversals had already been found to have coincided with the extinction of many species of plants and animals (TIME, Nov. 30). This led Durrani and Khan to speculate about what kind of event could cause the reversals and wreak the other damage at the same time. They concluded that the earth's magnetic field may be so precariously balanced (171 reversals in the past 76 million years) that even a small jolt would be enough to upset it. Such a jolt, they argue in a recent issue of Nature, could easily have been caused by a comet...
