The thylacine (Thylacinus cynocephalus), more commonly known as the Tasmanian wolf or Tasmanian tiger, was the largest modern marsupial carnivore until it went extinct in 1936.[1] Thylacines first evolved around 23 million years ago[2] and had become practically marsupial dogs,[note 1] both having adapted to similar niches. In their prime, thylacines were the apex predators of New Guinea, Australia, and Tasmania, although Tasmanian devils likely preyed on their young.[3] More than 4000 years ago, Asian traders introduced dingoes to Australia.[4] Dingoes and thylacines occupied different ecological niches (like the opossum eating in your trash can live in harmony with the raccoon also eating from your trash), but apparently shared diseases,[5] and thylacines became extinct on mainland Australia. A population persisted on Tasmania, but hunting continued, and in 1936, the species became extinct.
Cryptozoology[edit]
Despite its extinction, some 3800 unconfirmed sightings of the thylacine have been reported.[6] In addition, there are the usual dubious photographs and government funded searches that turn up nothing.[7][8] Some sightings apparently even come from mainland Australia and New Guinea,[9][10] where thylacines have been extinct for literally thousands of years.[11]
Cloning and genetics[edit]
In 1999, a project to clone the thylacine began, and even claimed a breakthrough.[12] Unfortunately, the project was canceled in 2005.[13] Some work has been done since on thylacine genetics, including the sequencing of the thylacine mitochondrial genome, and possibly getting the nuclear genome for $1 million.[14]

Notes[edit]
- ↑ Richard Dawkins once said in The Ancestor's Tale "...the skeleton [of a thylacine] is harder to distinguish [from a dog]. Zoology students at Oxford had to identify 100 zoological specimens as part of the final exam. Word soon got around that, if ever a 'dog' skull was given, it was safe to identify it as Thylacinus on the grounds that anything as obvious as a dog skull had to be a catch."
