On 6 September 1936, the ecological tragedy resounded when the lone thylacine Benjamin ended the glory of the Australian thylacine species at Hobart Zoo. In recent years, however, the anecdotal miracle seems to have happened, and the thylacine may not have been as completely extinct as we thought. Mysterious sightings, scientists' efforts, and the possibility of resurrection will all be presented in this 1,500-word essay.
On September 7, humans commemorate the extinction of Australian flora and fauna due to human ignorance, and the thylacine becomes a symbol of this tragedy. Once widespread in Australia, the thylacine was recorded as the last thylacine to die in the thirties of the 20th century. However, in recent years, a series of jaw-dropping sightings have come out, with local residents claiming to have seen thylacines at least eight times in the past three years. The claim has sparked widespread speculation and raised questions about whether the long-lost species is really extinct.
Zoologists have conducted an in-depth study of the thylacine's resurrection. Although there were rumors of thylacine sightings after 1936, it was not until 1967 that a decomposing thylacine carcass was discovered, which attracted the attention of scientists. However, until recent years, it was generally accepted by the scientific community that the thylacine was extinct. Despite this, zoologists have discovered thylacine specimens and proposed that the species could be resurrected in the next 50 years through DNA technology.
The mysterious resurrection of the thylacine is not an isolated case in the Australian animal kingdom. Similar events have occurred on Earth, such as the white-throated coot suddenly appearing on an uninhabited island after disappearing for tens of thousands of years. This phenomenon has surprised scientists and raised questions about the change of the ecological environment and the reappearance of extinct animals. Although there have been rumours of thylacine occurrence for a long time, zoologists have never seen a live thylacine, let alone photographed a recent thylacine**. Therefore, the existence of the sightings still needs to be supported by a large body of evidence.
The root cause of the thylacine's extinction was inextricably linked to the invasion of Europeans. Around 40,000 years ago, more than 90% of Australia's megafauna disappeared except for several species of kangaroos and thylacines. Thylacines are mainly found in the north-east, north-west and north-central regions of Tasmania, while when the Europeans landed, a brutal "bounty scheme" was implemented to protect sheep from thylacine attacks. The thylacine, believed to be the raider of sheep, became the target of hunting, which, combined with competition with dingoes introduced by European settlers, habitat erosion, food chain breaks, and the spread of distemper disease, led to the decline and eventual extinction of thylacine.
During the extermination of the thylacine, there were many misconceptions. The thylacine is believed to be the main culprit in the attack on sheep, yet there is growing skepticism about this claim. It wasn't until the last known thylacine was captured in Tasmania in 1930 that there was an offer to protect it. However, the response was too slow, the bail was issued too late, and "Benjamin the lone wolf" died two months later due to the negligence of the administrator.
In 1999, scientists at the Australian Museum launched a project to clone thylacine. DNA extracted from thylacine cubs preserved in ethanol became important research material. In 2001, scientists extracted more DNA and successfully copied the thylacine's gene. They hope to build a genetic database of thylacine's DNA by replicating all of the thylacine's genes on a large scale. Subsequently, scientists plan to implant thylacine's genetic material into other marsupial carnivores as their mothers, thus cloning a group of thylacines that can survive in the wild.
Whether the resurrection of the thylacine really becomes a reality, the efforts of scientists are exploring uncharted territory. However, whether successful or not, this process is a reminder that species on Earth continue to go extinct and that all we can do is protect them. A rupture of the ecological balance is not only the extinction of species, but can also trigger a chain reaction that affects the entire ecosystem. In the process of protecting flora and fauna, human beings should be careful so as not to fall into the tragedy of ignorance leading to the extinction of species again.
This article provides a profound overview of the history of the thylacine, an Australian animal, and the mysterious topics surrounding its resurrection. With a solid factual foundation and vivid descriptions, the author takes readers through time and space and goes back to the years when thylacines lived. From the lonely death of the last thylacine, Benjamin, to the tireless efforts of scientists to resurrect it, the essay is both a tragedy of extinction and an infinite reverie about the miracle of life.
First, by describing the history of thylacine's existence in Australia, the article shows the destruction of the ecological balance of nature by human activities. The extinction of the thylacine is not only related to the bounty scheme of Europeans, but also involves various factors such as habitat erosion and food chain breakage, presenting the tragedy of an extinction of a species oppressed by alien factors. This has triggered a rational reflection on the ecological environment of human beings, and warned us to protect nature while pursuing development to avoid the disappearance of more species.
Secondly, the article ignites the expectation of the miracle of life through the scientists' attempt to resurrect the thylacine. Advances in science and technology have opened new doors to this possibility, with cloning and DNA replication becoming the means by which it is possible. Although some breakthroughs have been made in science and technology, the article also objectively points out that there are still many challenges to the resurrection of thylacine in the scientific community. This makes the reader have to think rationally in the expectation of technology, and at the same time express admiration for the scientists' spirit of exploration.
In addition, the article provides an in-depth analysis of the reasons for the extinction of the thylacine, revealing various factors such as bounty programs and disease transmission at that time. The article defends the thylacine, once considered a "sheep killer", reminding people to maintain a scientific attitude when facing ecological problems, and not to blindly blame a certain species for superficial phenomena.
Overall, this article provokes readers to think about ecological issues, species extinctions, and the development of science and technology through an in-depth understanding of the history and scientific attempts of this particular animal. The vivid description, solid factual foundation, and clear discourse structure make the article both fascinating and show the author's deep thinking on the topic. It is hoped that people will have a deeper understanding of ecological and environmental protection and remain rational and optimistic about the prospects of science and technology after reading.
