Extinction
In
biology and
ecology,
extinction is the end of an
organism or of a group of organisms (
taxon), normally a
species. The moment of extinction is generally considered to be the death of the
last individual of the species, although the
capacity to breed and recover may have been lost before this point. Because a species' potential
range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as
Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the
fossil record) after a period of apparent absence.
