this is evolution and it happens quickly!

Am I the only one who thinks Tasmanian Devils are cute? Vicious looking, but cute.

Anyway, as to the story, that is an amazingly fast adaptation 0_0, though I think it is more a cultural adaptation on the part of the devils than it is a physiological adaptation. Maybe this species won't die out after all.

Isn't it just natural cause and action? Sounds wrong to call it evolution, and even adaptation.

In many species (not only mammals) the right to breed is strictly controlled by the stronger, adult individuals. But when they are mostly dead, what prevents the "teens" from breeding? Given enough food (which is present since the adults are dead) they will succeed.

The interesting part (that the article is not too clear on) would be if they were not previously able to breed at age 1, but has gained the ability in just 12 years.
