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
