Thylacines
Thylacines or, as they are more commonly know Tasmanian Tigers have been considered extinct in the Australian mainland for quite some time. However there is evidence suggesting that thylacines never really became extinct but have actually adapted to the challenges faced by them. To begin with, the habitat of the thylacine shows little evidence that it has changed drastically through the course of time. Next, the thylacine diet is still widely available, showing that food sources are still available. Lastly, the reports of sightings both questionable and probable are adding up, some are hoaxes and some are misidentification but some defy these explanations. Beginning with a condescend history of the thylacine in the world. Thylacines first appeared over 4 million years ago, they populated Australia, New Guinea and Tasmania. Theories surrounding the eventual extinction belief include the introduction of dingoes, human encroachment including the hunting and poisoning of the animals until the last known thylacine died in captivity in 1936 at the Hobart zoo as stated by the Australian Rare Fauna Research Association (2010). Since shortly after the death of the last known thylacine in 1936 over 3,000 sightings have been reported throughout the thylacines historic range.
Thylacines habitat has shown little or no change in over a thousand years. First, Thylacines were nocturnal hunters who rested by day in the timbers and scrubs and hunted on the boarders of thickets starting in the late afternoon and continuing into the night as stated by Le Souef in 1926 and Lord in 1927 collected from Natural Worlds (1996-2006). Secondly, According to The Heberle (1998) website formerly of the Department of Conservation and Land Management of Western Australia, Thylacines were most common in grassy plains, scrub and open forest. They were uncommon in dense forest. Finally, according to
