From here:
Alligators/Birds

"Alligators breathe like birds, scientists have discovered.

This similarity in breathing style may have arisen in a distant common ancestor of both animal groups, the researchers who made the discovery think, and may explain why that ancestor and one group of its descendants, dinosaurs, came to rule the world (at least for a while)."

Now why would God make a flying animal so closely related to a swimming animal?  Intelligent design?  Seems pretty stupid to me.

You can just hear their little minds working overtime:
-Right, so here's another bl00dy issue.
-Ahhh but let's look at it logically
-Right you mean we can say that Alligators spend a lot of time in the water, birds also spend time in the water (look at seagulls (see, if we emphasise the sea bit that'll make it even more associated with water
-Good, good, i see where you're going, carry on, carry on
-Well, these two animals obviously, actually and in fact both spend time in the water, therfore and ergo Our Creator would naturally
-Nice use of the word naturally there
-Cheers, would naturally use similar components for their breathing apparatii (thats a plooralizationism of apparatus)
-sounds good, keep going
-Ergo
-nice
-The use of common components actually prooves intelligent design and quite obviously and in fact, actually disproves evilution
-Haw, haw, that's always a good one!
-and thereby proves the Fact of Creation.
Ta Daaa!

Hahahahaha!

Yesterday i was watching a lecture by a guy from the Zeitgeist Movement. He kept talking like that all the time.
I like the general idea behind the Zeitgeist Movement and the Venus Project, but that way of speaking always gives me the creeps.

Truth, truth, half truth, ergo, conslusion.
In fact, unsupported claim, therefore, conclusion.
Actually, analogy, ergo, conclusion.

I had heard about this news a long time ago. Perhaps the evidence is new.

I'd like to see an animation.

I will look it up.

Ooooh... The air sacs... Perhaps this is it. I heard about it when scientists were considering the possibility that alligators breath like that, but the air sacs were thought to be necessary. I see.

I couldn't find a good animation to illustrate this way of breathing. =/

Would we see a mammal by the water's edge "suddenly" start breathing underwater(w/camera effect of course)?

   * She performed surgery on six anesthetized alligators and inserted flow meters, which measure the direction and speed of airflow, into their lungs.
   * She also pumped air in and out of lungs removed from four dead alligators and monitored the flow.
   * Lastly, using lungs from another dead alligator, she pushed and pulled water through the lungs with tiny fluorescent beads, making movies to show the direction of flow.

All of these experiments showed the same result: The air flowed through the lungs in just one direction.

They cannot argue with this data. I have three lines of evidence. If they don't believe it, they need to get an alligator and make their own measurements.
Yeeeeah!

I like this woman.

I saw this article in wired a few days ago. It's quite interesting and is yet another piece of evidence supporting evolution that the creationists will dispute without good reason.

Not a big surprise, remember that the bird teeth mutation resulted in conical alligator/crocodile teeth.

Chicken Teeth

"What we discovered were teeth similar to those of crocodiles—not surprising as birds are the closest living relatives of the reptile," said Mark Ferguson of the University of Manchester.

What happened

Around 300 million years ago, the ancestor of all modern vertebrates gave rise to two lineages, the mammals and the reptiles/birds. The oldest reptiles, such as crocodiles and alligators, had cone-shaped teeth. So did the earliest birds, called archosaurs.

Then, around 80 million years ago, modern birds emerged without teeth.

"So what would you expect bird teeth to look like? You would expect them to have teeth like their ancestors and their most closely related living relative," study co-author John Fallon of the University of Wisconsin told LiveScience.

Indeed, Talpid's teeth are conical, much like an archosaur's and closely resembling the teeth of a baby alligator or crocodile, Fallon said. If the chick survived, the teeth would most likely reabsorb into the mouth.

The archosaurs had mouths similar in shape to a reptile's. It turns out that developing a beak caused birds to lose their teeth.


Just more evidence demonstrating that we are all related.

Pogge:” This is the volume of a sphere with a 62 kilometer (about 39 miles) radius, which is considerably smaller than the 2,000 mile radius of the Earth.”
Wikipedia:” For Earth, the mean radius is 6,371.009 km(≈3,958.761 mi; ≈3,440.069 nmi).”
Wisp to Lester (on Pogge): Do you admit he was wrong about the basics?
Lester: No

The few that will look at this piece of evidence will.

Thanks for the article. I could see the video of fluorescent beads in salty water flowing in the lungs, but i would like an animation.
