Last known individual of a species or subspecies From Wikipedia, the free encyclopedia
This article is about the last remaining member of a taxon. For the TV series, see Endlings (TV series). For the album, see Endling (album).
An endling is the last known individual of a species or subspecies. Once the endling dies, the species becomes extinct. The word was coined in correspondence in the scientific journal Nature.
The last known thylacine (Tasmanian tiger), photographed at Hobart Zoo in 1933.
The 4 April 1996 issue of Nature published a correspondence in which commentators suggested that a new word, endling, be adopted to denote the last individual of a species.[1][2] The 23 May issue of Nature published several counter-suggestions, including ender, terminarch, and relict.[1][3]
The word endling appeared on the walls of the National Museum of Australia in Tangled Destinies, a 2001 exhibition by Matt Kirchman and Scott Guerin, about the relationship between Australian peoples and their land. In the exhibition, the definition, as it appeared in Nature, was printed in large letters on the wall above two specimens of the extinct Tasmanian tiger: "Endling (n.) The last surviving individual of a species of animal or plant". A printed description of this exhibition offered a similar definition, omitting reference to plants: "An endling is the name given to an animal that is the last of its species."[4][5]
In The Flight of the Emu: A Hundred Years of Australian Ornithology 1901-2001, author Libby Robin stated that "the very last individual of a species" is "what scientists refer to as an 'endling'".[6]
In 2011, the word was used in the Earth Island Journal, in an essay by Eric Freedman entitled "Extinction Is Forever: A Quest for the Last Known Survivors". Freedman defined endling as "the last known specimen of her species."[7]
In "The Sense of an Endling", author Helen Lewis describes the notion of an endling as poignant, and the word as "wonderfully Tolkien-esque".[8]
Author Eric Freedman describes endling as "a word with finality", stating, "It is deep-to-the-bone chilling to know the exact date a species disappeared from Earth. It is even more ghastly to look upon the place where it happened and know that nobody knew or cared at the time what had transpired and why."[9]
This is not a comprehensive list of contemporary extinction, but a list of high-profile, widely publicised examples of when the last individual of a species was known.
Birds
A dusky seaside sparrow (Ammodramus maritimus nigrescens), officially declared extinct in 1990.
The passenger pigeon (Ectopistes migratorius) became extinct at 1 p.m. on 1 September 1914 with the death of Martha, the last surviving member of the species, at the Cincinnati Zoo.[10][11]
Incas, the last known Carolina parakeet (Conuropsis carolinensis), died, also at the Cincinnati Zoo, on 21 February 1918.[11] The species was officially declared extinct in 1939.
Booming Ben, a solitary heath hen (Tympanuchus cupido cupido), was last seen 11 March 1932 on Martha's Vineyard, Massachusetts.[12]
The last known Kauai O'O (Moho braccatus) was recorded singing a mating call on Kauai in 1987 by David Boynton. The bird is believed to have been killed by Hurricane Iniki in 1992, and the death of this individual also marked the extinction of the entire Mohoidae family.[14][15]
Mammals
This section appears to contradict the article Thylacine. (March 2024)
In 1627, the last aurochs (Bos primigenius), an ancestor of bovine and cattle, died in a forest near what is now Jaktorów in modern-day Poland.[16]
A quagga mare at the London Zoo in 1870. This is the only specimen photographed alive.
The quagga (Equus quagga quagga) became extinct in the wild in the late 1870s due to hunting for meat and skins, and the subspecies' endling died in captivity on 12 August 1883 at the Artis in Amsterdam.[17]
On 7 September 1936, the last known captivethylacine (Thylacinus cynocephalus), also called Tasmanian tiger, died in Hobart Zoo, following persecution of the species through hunting and trapping. Information published about this individual has been conflicted throughout the decades following its death.[18] Areas of contention include whether it was male or female, whether it was named "Benjamin" or not, where it was captured, by whom it was captured, whether it was neglected in its zoo enclosure and even whether it was the last known surviving Thylacine.[18] A comprehensive analysis of the history of this individual published in 2023 concludes or re-affirms that it was male, captured on 7 July 1930, at Penney's Flats in northwestern Tasmania by Roy and Dan Delphin, never called Benjamin during its lifetime and that it was the most valued animal in the zoo's collection, not neglected, and that it died of old age.[18] Although it is generally accepted the Thylacine probably persisted in the wild following the death of this individual,[19] the Tasmanian Tiger at Hobart Zoo is considered the endling not only for its species, but also the family Thylacinidae.
The last known Mexican grizzly bear (Ursus arctos horribilis), also called oso plateado (silver bear) in Spanish, was shot in 1976 in Sonora, Mexico.[20]
Celia, the last Pyrenean ibex (Capra pyrenaica pyrenaica), was found crushed by a tree on 6 January 2000 in the Spanish Pyrenees, after hunting and competition from livestock reduced the population to one individual.[21]
After being considered possibly extinct for 113 years, a Fernandina Island Galápagos tortoise named Fernanda was found in 2019. However, she is the only confirmed individual.[24]
A tank in the Bristol Zoo was the last refuge of Partula faba, a land snail from Ra'iātea in French Polynesia. The population dropped from 38 in 2012[26] to one in 2015.[27] The last individual died on 21 February 2016.[27]
Some seeds were found in an archeological excavation in the Judean desert in 1986-87. In 2009, a specimen of an unknown species of Commiphora was successfully sprouted from one of these ancient seeds (dated 993 CE–1202 calCE). The tree was named Sheba. In 2024, it was tentatively identified as tsori or Judean balsam, on the basis of taxonomy and resin properties matching ancient descriptions. Similar to Fernanda, Sheba is the only known individual of her species despite recent discovery or rediscovery. [31]
