Biological Extinction in Terms of Overadaptation
Extinction has been a common phenomenon of the biosphere during the Earth’s past but it is also an enigmatic process in biological evolution. Various and numerous theories have been put forward to explain biological extinction, especially to explain mass extinction which marks the biostratigraphical boundaries in geohistory. Most of these explanations, however, rely too much either on somewhat simple internal or external factors of biota. As a result, no reliable theory of biological extinction has been developed though phylogenetical trees have been presented in various ways for different taxonomic groups (Fig. 1).
