In the English language, there are few words that convey a sense of finality quite like "extinction." The notion that a species could completely disappear from the planet forever — down to literally the last individual — is incredibly sobering.
But how "final" is extinction? How can scientists be sure that an animal has, in fact, completely disappeared forever?
As sampling and surveying techniques improve and more and more eyes and camera lenses are trained on broader and broader swaths of the planet, supposedly extinct animals like the Coelacanth and Attenborough's Long-beaked Echidna have been rediscovered like Lazarus rising from the grave.
In this quick-hit episode, we pose the question to our resident biologist of how extinction is determined, whether it's reversible and, if so, why bringing an animal back might not be a morally sound path to take.
