Until now, this scientific revolution has remained unknown to the general public. The new mode of thought focuses particularly on a single question: Why have island ecosystems always suffered such high rates of extinction? In our own age, with all the world's landscapes, from Tasmania to the Amazon to Yellowstone, now being carved into islandlike fragments by human activity, the implications of island biogeography are more urgent than ever. Why do marsupials exist in Australia and South America, but not in Africa? Why do tigers exist in Asia, but not in New Guinea? Influenced by MacArthur and Wilson's book, an entire generation of ecologists has recognized that island biogeography -the study of the distribution of species on islands and islandlike patches of landscape - yields important insights into the origin and extinction of species everywhere. ![]() ![]() In a book titled The Theory of Island Biogeography, they presented a new view of a little-understood matter: the geographical patterns in which animal and plant species occur. Wilson triggered a far-reaching scientific revolution. Thirty years ago, two young biologists named Robert MacArthur and Edward O.
