This source is listed as the evidence for the claim that scientists have the ability to reintroduce extinct species into today's world.
Taking a deeper dive into the validity of this source, we see that it was posted by Tom Clarke, a 'science and technology editor'. Sky News is a news company based in the UK and was created in 2018.
Tom specifically states that, "scientists claim to have made progress towards "de-extinction" and estimate their DNA sequence for the thylacine - or Tasmanian tiger - is 99.9% accurate."
Tom sites a source from Collosal Biosciences, based in Dallas, which have spoken previously about bringing back other species, including the Wooly Mammoth and the Dodo Bird.
Tom even includes a rebuttal section, in which he references that there are scientists who believe the notion of reintroducing extinct species is futile due to its technical difficulty.
To further fact check this claim, I took a look at some other sources of information relating to the claim. I found this site,
https://www.labiotech.eu/in-depth/crispr-de-extinction-to-bring-back-animals/ which asks the same question, but specifically includes the gene editing technology CRISPR in their claim.
I believe this claim to be valid, considering that the words were lifted from scientists who have both reputable and credible data that supports the claim. In addition, the claim is even more valid because it does not state that reviving this species is guaranteed, but rather that it is just possible. This claim can also be found in other reputable places, such as the Labiotech source referenced above.
