Gingrich called the moment "mystical, magical." More than any of his early wins, the romp through the first 100 days, the votes on tax cuts and regulatory reform, this one was hard, a truer measure of whether the new ecosystem he had created in the House would actually work the way he planned. "You can't, in a free society, postpone permanently major arguments," he says, " and the job of leadership is to manage it."

...during the Cambrian itself, and they probably occurred for no obvious reason. Rather, just as the tiniest touch can cause a steeply angled sand pile to slide, so may a small evolutionary advance that gives one species a temporary advantage over another be enough to bring down an entire ecosystem. "These patterns of speciations and extinctions, avalanching across ecosystems and time," warns Kauffman, are to be found in every chaotic system - human and biological. "We are all part of the same pageant," as he puts it. Thus, even in this technological age, we may have more in common than...

"This new report represents an unprecedented number of scientists," says Dorfman, "The problem with biodiversity studies in the past is that they used too small a sample to yield significant results, or studied a specific ecosystem and then make grandiose claims for the data. If this is as wide a sample as claimed, it could be very important...
...scientists and conservationists, the answers are crucial. The Galapagos is not just an exotic vacation spot; it is a unique ecosystem where biology and geology have gone to bizarre and instructive extremes. The archipelago's 15 main and 106 smaller islands are dotted with the volcanoes that gave birth to the Galapagos more than 3 million years ago; some are still active. Opuntia cactus, spiny acacias and palo santo trees have taken root amid the hardened lava of the lowlands. On some of the largest islands, the higher elevations have patches of dense, moist forests dominated by Scalesia trees, which...
FRANCE A NUCLEAR POWER? THIS MAY BE feasible, there may be credence to it, but to what avail? These tests have been carried out in total disregard for the environment and the hazards posed to the ecosystem. What's more, the impounding of Greenpeace vessels by the French defies international convention. ALNASHIR D. WALJI Nairobi...
