A fascinating history of species extinctions, their causes and the looming "sixth extinction". Explores the history of this search, its subjects, its controversies, its current conclusions, and their implications for our efforts to preserve Earth's biodiversity. It explains what extinction is, what causes it and whether it is preventable, and by comparing past geological extinction events, it aims to predict what will happen in the future--P. [4] of cover.

The extinction that wiped out 95% of the living species at the end of the Paleozoic era can be explained by the fact that when it happened, all landmasses were one continent, Pangea, with an inner ocean, the Paleo-Tethys. This ocean included the richest n

Over the last half a billion years, there have been five mass extinctions of life on earth. Scientists around the world are currently monitoring the sixth, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. Elizabeth Kolbert combines brilliant field reporting, the history of ideas and the work of geologists, botanists and marine biologists to tell the gripping stories of a dozen species – including the Panamanian golden frog and the Sumatran rhino – some already gone, others at the point of vanishing. The sixth extinction is likely to be mankind's most lasting legacy and Elizabeth Kolbert's book urgently compels us to rethink the fundamental question of what it means to be human.

The present book combines three main aspects: five major mass extinctions; contributions on some other minor extinctions; and more importantly contributions on the current mass extinction. All three aspects are introduced through interesting studies of mass extinctions in diverse organisms ranging from small invertebrates to mammals and take account of the most accepted subjects discussing mass extinctions in insects, mammals, fishes, ostracods and molluscs.

Excerpt: The Permian-Triassic (P-Tr) extinction event, informally known as the Great Dying, was an extinction event that occurred 251.4 Ma (million years ago), forming the boundary between the Permian and Triassic geologic periods. It was the Earth's most severe extinction event, with up to 96% of all marine species and 70% of terrestrial vertebrate species becoming extinct It is the only known mass extinction of insects. Some 57% of all families and 83% of all genera were killed. Because so much biodiversity was lost, the recovery of life on Earth took significantly longer than after other extinction events. This event has been described as the "mother of all mass extinctions." Researchers have variously suggested that there were from one to three distinct pulses, or phases, of extinction. There are several proposed mechanisms for the extinctions; the earlier phase was likely due to gradual environmental change, while the latter...

Extinction is the ultimate fate of all biological species - over 99 percent of the species that have ever inhabited the Earth are now extinct. The long fossil record of life provides scientists with crucial information about when species became extinct, which species were most vulnerable to extinction, and what processes may have brought about extinctions in the geological past. Key aspects of extinctions in the history of life are here reviewed by six leading palaeontologists, providing a source text for geology and biology undergraduates as well as more advanced scholars. Topical issues such as the causes of mass extinctions and how animal and plant life has recovered from these cataclysmic events that have shaped biological evolution are dealt with. This helps us to view the biodiversity crisis in a broader context, and shows how large-scale extinctions have had profound and long-lasting effects on the Earth's biosphere.
