Extinction of any species is caused by either the complete loss of all indivduals of the species, by the inability of the remaining individuals to successfully reproduce or by a reduced genepool that is not diverse enough for the species to survive long term or outside of controlled captivity.
While some species have been brought back from the brink of extinction most of these species will not survive long term due to a diminished gene pool that cannot adapt to change. (logged out during edit again).
