Perhaps the lesson is that some species deserve to go extinct.
Take the Panda, for example.
Big and fat, giving birth to tiny offspring that are accidentally crushed by their mothers at an alarming rate.
Too antisocial and ill-tempered to tolerate one another, even long enough to breed.
In a world with thousands of bamboo species they will eat only seven.
All that tells me this species does not make the cut to go to the next round.
