Newell (18) implicitly provides a practical definition: “Extinction... is not simply a result of <br class="">environmental change but is also a consequence of failure of the evolutionary process to keep pace with changing conditions in the physical and <br class="">biological environment” (18). In other words, catastrophe results when the rate of environmental change exceeds a threshold.”<br class=""><br class="">Daniel H. Rothman.
