"The difference is that olympic long jumpers get to the pit via mechanized transport. The frogs on the otherhand get to the front line by using their legs."

You're getting smarter Bob, now you should be able to look at your explanation and see why talk of evolution in this regard is laughable. The long legged among any species should be able to walk faster, but that fails to prove an advantage in getting there, and has nothing to do with evolution. What if they have advanced to their own destruction?

"Not only were the legs of pioneer toads significantly longer, but the same athletic build dies out among toads as areas become more settled."

This is understandable, at soem point the pioneer toads outgrew the beds in the pioneer toad motels causing back problems from sleeping on the floor. At which point the tortoise toads won the race.

"What if they have advanced to their own destruction?"

Then their evolution wasn't quite so prescient after all.

It's not just that it can walk faster, but it can cover more ground. As the article mentions the faster frogs are able to cover more ground per year than the frogs could decades ago. It stands to reason that the type of frogs furthest from ground zero will be of the faster variety simply because the slower types cannot get that far. Fast frogs produce more fast frogs. So it makes total sense that the front line should be dominated with fast frogs.
