14、sed with government authorities. 17 Disaster struck 250 million years ago, when the worst devastation in the earths history occurred. Called the end-Permian mass extinction, it marks a fundamental change in the development of life. The history of life on the earth is replete with catastrophes of var
15、ying magnitudes. The one that has captured the most attention is the extinction of the dinosaurs and other organisms 65 million years ago between the Cretaceous and Tertiary periods-which claimed up to half of all species. As severe as that devastation was, it pales in comparison to the greatest dis
16、aster of them all: the mass extinction some 250 million years ago, at the end of the Permian period. Affectionately called “the mother of mass extinctions“ among paleontologists (with apologies to Saddam Hussein), it yielded a death toll that is truly staggering. About 90 percent of all species in t
17、he oceans disappeared during the last several million years of the Permian. On land, more than two thirds of reptile and amphibian families vanished. Insects, too, did not escape the carnage: 30 percent of insect orders ceased to exist, marking the only mass extinction insects have ever undergone. B
18、ut from catastrophes, opportunities arise. For several hundred million years before the end-Permian event, the shallow seas had been dominated by life-forms that were primarily immobile. Most marine animals lay on the seafloor or were attached to it by stalks, filtering the water for food or waiting
19、 for prey. In the aftermath of the extinction, many once minor groups-active, predatory relatives of modern-day fish, squids, snails and crabs were able to expand. Some completely new lineages appeared. This ecological reorganization was so dramatic that it forms a fundamental boundary in the histor
20、y of life. Not only does it demarcate the Permian and Triassic periods, it also establishes the close of the Paleozoic era and the start of the Mesozoic era. The modern tidal pool reflects what lived and what died 250 million years ago. Over the past few years, exciting new insights into the causes
21、and consequences of the end-Permian mass extinction have poured in from virtually every branch of the earth sciences Some of these findings include detailed studies of rapid changes in ocean chemistry, more thorough documentation of extinction patterns and new analyses showing that large volcanic er
22、uptions occurred at the Permo-Triassic boundary. How much do mass extinctions contribute to the evolution of a group, as compared with long-term adaptive trends? For example, sea urchins are ubiquitous in modern oceans but were relatively uncommon during the Permian. Only a single genus, Miocidaris,
23、 is known for certain to have survived the extinction. Did Mioeidaris survive by pure chance, or was it better adapted? Would sea urchins today look any different had it not been for the end-Permian extinction? To resolve such questions, we need to learn more about the causes of the catastrophe and
24、how those species that survived differed from those that disappeared. The key sources for this information are rock layers and fossils. Unfortunately, samples from the late Permian and early Triassic are notoriously difficult to come by. The fossil record across the boundary is plagued by poor prese
