What's Happening?
Researchers have analyzed the genome of the thylacine, also known as the Tasmanian tiger, to understand its extinction. The study, conducted by scientists at the Indian Institute of Science Education and Research Bhopal, found that the thylacine lost crucial genes millions of years before humans arrived in Australia. These genetic losses may have made the species more susceptible to environmental changes and diseases. The thylacine was the last member of the Thylacinidae family, which once inhabited Australia and New Guinea. It became extinct on the Australian mainland about 2,000 years ago, primarily due to human hunting and competition from dingoes. The last known thylacine died in Hobart Zoo in 1936.

Why It's Important?
The study highlights the role of genetic factors in the extinction of species, suggesting that the thylacine's genetic makeup made it vulnerable to environmental changes and diseases. This research provides insights into the conservation of current species facing similar threats. Understanding the genetic vulnerabilities of hypercarnivores like the thylacine can inform conservation strategies for other endangered species, such as the Bengal tiger. The findings emphasize the importance of genetic diversity in species survival and the potential impact of climate change on biodiversity.
What's Next?
Further research is needed to confirm the link between the loss of specific genes and the thylacine's susceptibility to disease. Scientists may explore similar genetic studies on other endangered species to identify vulnerabilities and develop conservation strategies. The study could lead to increased efforts to preserve genetic diversity in wildlife populations, potentially influencing conservation policies and practices.
Beyond the Headlines
The research raises ethical questions about human responsibility in the extinction of species and the importance of preserving biodiversity. It also highlights the long-term impact of climate change on genetic diversity and species survival. The study may prompt discussions on the role of genetic engineering in conservation efforts.
