What is a Hyperdisease--and What Could It Have Done to Life on Earth?
Remember when headlines announced that an asteroid impact caused the extinction of the dinosaurs? Even though this theory was widely popularized, not all scientists agree with it. They do agree that extinction, like evolution, is an integral part of the pattern of life on earth, and also that the overwhelming majority of extinction events have occurred in clusters. But the factors which have caused most extinctions have yet to be determined.
