In a general sense, the term '''extinct''' means no longer active or living. It is sometimes applied to kinds of organisms, to cultures, to religions, to geological processes (e.g. "extinct volcano"), to social movements, and, essentially, to any other object or process to which the concept of life or activity is applicable.

It is sometimes applied to kinds of organisms, to cultures, to religions, to geological processes (e.g. "extinct volcano"), to social movements, and, essentially, to any other object or process to which the concept of life or activity is applicable. It could be argued that it can occur before that, say, if there are only [[male]]s or [[female]]s left in a sexually reproducing species, or if the remaining pairs are geographically isolated preventing [[mating]].
In the specific biological/paleontological sense, "extinct" refers to the loss of all living representatives of a taxon (that is, of all the members of a species, a genus, a phylum, etc.).

[[Cloning]] is a new [[technology]] that is being developed that could possibly bring back organisms into existence. The [[woolly mammoth]] and other organisms whose [[DNA]] is preserved such as the [[Thylacine]] of [[Australia]] are realistic options to be brought back using the cloning technique.

[[Evolutionist]]s believe that over the [[history]] of the earth, many more species have become extinct than have existed at any one time. Sometimes a species is replaced by [[descendant]]s that have altered their form enough not to be considered the same species anymore. An example of this is the history of the modern horse, which has descended through a series of distinct, and now extinct, [[precursor]] species.
