Termination of a taxon by the death of its last member
Extinction is the termination of a species or other taxonomic unit when the last individual dies. It can also occur functionally when a species can no longer sustain a viable population, even if some survive. Extinction is a natural part of evolution, often caused by environmental changes or competition. However, in recent times, human activities have greatly accelerated extinction rates, leading to the loss of numerous species worldwide. A dagger symbol (†) placed next to the name of a species or other taxon normally indicates its status as extinct. Definition.
