Looks like the world-wide amphibian die-off we've been hearing about for a while now is slowing due to the frogs in question evolving and becoming immune to the fungus that has been killing them.

Do they? Do they actually evolve (physically evolve) rapidly, or just adapt rapidly? I heart me some evolution talk. Love to learn new things in this area.

Rarely does anything evolve "rapidly", at least as a human being would see as rapid. Adaptation, however, can be very quick, and if something can adapt to survive a hostile environment, then it keeps on living and breeding...which then would give it a better chance to eventually evolve. At least, that's the logic I'm employing here.
Remember:
1. All living things change through time in order to survive in their environment.
2. Adaptation involves short-term changes to suit the habitat and environment.
3. Evolution is a long-term process wherein changes occur in the genetic level for a better functioning and survival as a race.

Soooo..... a build up of resistance to a fungus by frogs is proof of evolution?
Guess this proves Europeans were more highly evolved than American Indians, huh?
Natural selection and adaptation within a species would also account for it, and such adaptation can disappear again. And through it all, they remain frogs.
Take a frog, turn him into a squirrel. That would impress me.
I'll consult with my pastor to verify the validity of the report above.
I sent out a broadcast to all the gods to attempt to verify, but as usual not a single one of them responded. It really raises concerns in my mind that gods might just be an urban legend........... on steroids

An adaptive change by anything on earth is neither "higher" nor "lower". It's simply more appropriate to the current environment. Europeans weren't more "highly" evolved than Native Americans. They were simply evolved to survive in *their own* environment which included certain diseases (some of which wiped Europeans out in HUGE numbers initially, BTW). These diseases didn't exist in the Americas before the Europeans came, as far as anyone can tell, so the Native Americans didn't need to develop a resistance to them, as far as their bodies and biology knew.
It has nothing to do with "higher" or "lower". It has to do with change happening within a given environment that helps one survive within *that* environment.
