Not quite evolution. The red-bellied black snake and the green tree snake with larger heads have killed themselves off through eating cane toads; therefore, the snakes with the smaller heads, that can't eat the toads, are going to be the ones left to reproduce. The snakes aren't evolving. The individuals with certain characteristics are just be handed a reproductive advantage....
On another subject (not evolution):
Doesn't Australia have a long history of bringing in outside species to "solve problems", and then the outsiders themselves end up becoming a new problem?
Cool. :-)
No, natural selection is currently taking place in the snake population of Australia.
Not insignificant, but not evolution, unless there is evidence new genes or a new species.
One also has to chuckle at the anthropomorphic "nature is taking care of itself" commentary, which sound like declarations of faith. "Nature is happening" is closer to the mark.
I wonder, what animals indigenous to Queensland that were subject to the predation of larger headed snakes might now have their populations not so efficiently controlled?
So, are the dead snakes reproducing?
Or, are other snakes watching and telling their babies not to grow such big mouths?
"evolution" my a$$!
I won't touch that comment.
Worth watching.
