IUCN Red List

Extinction is when a species of animal, plant, or other organisms are no longer living. Extinction is one of the major features of evolution.

All species become extinct sooner or later. The end of a species may happen for many reasons. It may be caused by habitat loss or by being overhunted, or by a major extinction event. An example of an animal that is now extinct is the Dodo, from over-hunting. Another quite different way for a species to end is by species-splitting, known as cladogenesis. The species living today probably were not living in the Cambrian period, but their ancestors were. view more...
