Researchers at DNA Zoo Australia have mapped the genome of the numbat for the first time. The milestone is notable in its own right, motivated by a desire to improve conservation efforts for the endangered termite-eating marsupial, which is now found only in small pockets of Western Australia.

But in announcing the development last week, scientists also had a more extraordinary suggestion: that the numbat’s DNA could be used as a blueprint to bring its extinct cousin, the thylacine, back from the dead.
