Great news! Finally, an animal that can devour a Bufo marinis toad and not only live to tell the tale, but devour yet another when the opportunity presents itself. The cane toad has been needing an effective predator in Oz for a long time.
It is not inconcievable that these animals could develope a resistance to the toad's venom, much as has our San Francisco garter snake, who's main dietary item is a poisonous species of salamander.
Yeah, yeah, I know, it's still just a stupid snake. But so what? It's still evolution, and it's working.

What came first the chicken or the egg?
How do plants exist without bugs in the soil, and bugs in the soil without plants producing oxygen?
There are no atheists in foxholes
Underlying the evolutionary theory is not just the classic "stuff" of science — conclusions arrived at through prolonged observation and experimentation. Evolution is first an atheistic, materialistic world view. In other words, the primary reason for its acceptance has little to do with the evidence for or against it. Evolution is accepted because men are atheists by faith and thus interpret the evidence to cor-respond to their naturalistic philosophy.
For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears; And they shall turn away their ears from the truth, and shall be turned unto fables. II Timothy 4:3,4
II Thess. 2:11 And for this cause God shall
send them strong delusion, that they should believe a lie:
You can not see the 'wind', but you can see its effect!!!!
Evolution was caused by genetic mistakes at each stage?
Radical Evolution has 500 million years to find fossils of fictional drawings of (hard core)missing links, yet they find none.
We have not seen such moral darkness since the dark ages, coencides with
teaching evolution in schools. (Moral darkness)
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places, EPH 6:12.
"Thus, many scientists embracing naturalism find themselves in the seeming dilemma recently articulated by biochemist Franklin Harold: "We should reject, as a matter of principle, the substitution of intelligent design for the dialogue of chance and necessity [i.e., Darwinian evolution]; but we must concede that there are presently no detailed Darwinian accounts of the evolution of any biochemical system, only a variety of wishful speculations."

I doubt that species snake is developing a resistance to the toad. More likely a favorable mutation occurred in one and passed it down to the next generation. Or there were snakes that could eat them but their numbers were low...until now.
Kinda like the Black Death and humans. Some survived because of there genes.

Precisly. It is the population that will eventually develope the resistance. This can readily be seen in a species (forget which one) of westen ground squirrel, It's main preditor is the a rattlesnake (C. v. viridis). The squrrel has attained quite a stronge resistance to the snake's venom and the snake has to get a really good hit to kill one.
But of course, these things go hand in hand. The snake's venom has become 'hotter.'

And verlch, as you've been shown ad nauseum, that is covered quite well eleswhare. If you wish to go back through it again, I suggest you go back through your own, earlier threads.
Ok, put up or shut up, friend V; show me emperical evidence in support of the creation myth.

Hmm.. Maybe I was confused by your concept of resistance. In short it's adaption.
The species could definitely develop a resistance. Those squirrels which did not have the genetic marker or stronger constitution would die off. The gene police took em out of the pool.

That's pretty much what is happening. The squirrels in the affected populations are born with this resistance.
Apparently, the snakes feeding on the cane toads are not resistant, they arte simply unable to eat other than smaller toads, thereby taking in less than fatal doses of toxin. It remains to be seen if they will develope a resistance.

Details first known mammal feeding on a dinosaur.
The dinosaur was very small and needed salt.
This, of course, does not disprove evolution, but does challenge the idea that very early mammals left dinosaurs alone. |
