Tasmania's extinct tiger

Researchers in Australia and the US are embarking on a multi-million dollar project to bring the Tasmanian tiger back from extinction. The last, officially named "thylacine" died out in the 1930s. The thylacine got its nickname of the Tasmanian tiger for the stripes along its back.

The team behind the bid say it can be recreated using stem cells and gene editing technology and the first thylacine could be reintroduced into the wild in 10 years, while other experts are skeptical.

The group of Australian and American scientists plans to take stem cells from a living marsupial species with similar DNA, and then use gene editing technology to "bring back" the extinct species or an extremely close approximation of it.

It would represent a tremendous achievement for the researchers who would try it and would require a series of scientific discoveries.

Tasmanian tiger populations were decimated when humans arrived in Australia tens of thousands of years ago. The last captive Tasmanian tiger died at Hobart Zoo in 1936. If scientists succeeded in reviving the animal, it would mark the first "de-extinction" event in history, but many outside experts doubt the science behind it. her.

"Extinction is fabulous science," Associate Professor Jeremy Austin of the Australian Center for Ancient DNA told the Sydney Morning Herald, adding that the project was "more about media attention for scientists and less about doing serious science".

The idea of ​​reintroducing the Tasmanian tiger has been around for more than 20 years. In 1999, the Australian Museum began pursuing a project to clone the animal, and since then various attempts have been made at intervals to extract or reconstruct viable DNA from the samples.

This latest project is a partnership between scientists at the University of Melbourne and Texas-based company Colossal.
