The slutty female frogs never get any credit.

To find a recently evolved species like this is exceptional, at least in my experience

this guy has never seen females in the left's NOW organization

Females, who choose mates based only on their call,

Hey! Just like Feminists! Maybe this will help drive Liberals to extinction.

You'd think that one example of something that evolved would be the final nail in the coffin, but of course 'they' are driven by something other than science. It never was about science.

I don't understand. The southern group was isolated from the other group for a long period of time, but didn't develop this "speciation" -- they were supposedly all still compatable.

But then, having found each other again, the same behavior (breeding only among southern frogs) led to a speciation in only 8000 years?

What was different between the physical separation and the "choice" separation?

Isn't it much more likely that the southern population already have females which were incompatable with the other group? And when they started inbreeding again, those who couldn't get pregnant from the northern group would have babies which couldn't get pregnant from the northern group?

Meanwhile those who still COULD would randomly get inpregnated from their own group OR the northern group, and since the cross-breed children were inferior they tended to die out?

So over time simple natural selection tended to select toward those southern frogs who could only get pregnant by inbreeding?

How do they know what the ones from 8000 years ago did?


And it is rational that frogs would somehow notice their children were dying if they bred with the "wrong" frogs, and some of them would be smart enough to change their behavior and only breed with the "right" frogs?

That seems like a stretch even for true believers.

Does seem that extraordinary to me as many new species (or subspecies depending on your view) form during short periods of isolation.

Try another reading of the article. Evolution takes many generations. It isn't that the parent frogs didn't "notice" that the babies were dying. It's that the babies that lived made more babies. Some of these babies were attracted to the frogs that they did well with when mating. Those pairings had babies, and so on, and so on. It's not about a single generation. It's about 8000 generations. Read more closely and you'll get it. Frogs rarely live past a couple of matings, you see.

Hey, if it's in Websters, it has to be true. Right?

The evolution of this species took far fewer than 8,000 years:

Hopefully, the damage to our environment will also linger less than 8,000 years.

This guy didn't see John Kerry's 'Senate voting record' during the last election. Seriously, where is the chart showing a frog going to a lizard, going to a butterfly going to an elephant? Oh well.

Well, according tho what I read...it's still a frog. What did the frog evolve into? Not a very strong case for evolution.
