Dinosaur-Bird evolution

Theropod dinosaurs are a clade that was defined by bipedalism, feathers, and relatively high brain organization.
Also a particular respiratory system, and bone growth pattern.
All these traits are also found among birds.

They lied about that bigtime.
Cartoons and animation is how the uneducated push FAKE NEWS.

The fantasy generator has been turned loose. Avoided protein discussion.

One big deal breaker junior Darweeniest can't cope with is the bird lungs and bones.

Fantasy story time from Chuckland.

KU takes center stage in bird-dinosaur debate​



LAWRENCE--Larry Martin expects his work to ruffle some feathers among people who believe that birds evolved from dinosaurs.

Martin, senior curator at the Natural History Museum at the University of Kansas, recently co-authored a study with several other scientists on "Longisquama insignis," a small reptile with feathers that glided among the trees some 220 million years ago in what is now central Asia.

Because Longisquama, a contemporary of the earliest dinosaurs, existed some 75 million years before the first birds, Martin says he believes it--not dinosaurs--was among birds' first ancestors. And, unlike early dinosaurs, fossils of Longisquama show the same unique sheath that surrounds growing feathers in modern birds.

"Everything you can make out is consistent with it being a small, tree-living, gliding animal, which is precisely the thing you'd expect birds to evolve out of," Martin says.

The results of the study appear in the June 23 issue of the journal Science.

Martin's conclusion that birds did not evolve from dinosaurs is going against popular opinion. Practically everyone--from established scientists to best-selling authors and major Hollywood directors--tends to believe the theory that dinosaurs were birds' earliest ancestors. Martin says that is just wishful thinking.

"People want to believe that birds came from dinosaurs because it would mean that dinosaurs aren't really extinct," Martin says. "People want to believe that the parakeet in a cage is a cousin of the Tyrannosaurus Rex."

If Martin wants an informed opinion to dispute his claims that birds and dinosaurs are not of the same feather, all he has to do is open his office door in the Natural History Museum and call out for David Burnham.



Once again jr Darwinists blow smoke.

Why should anyone listen to a local that went nowhere in college?

Ok. Thats not the video I posted.
This is.
So who has the power to swap out a video?

Huh? Who lied about what bigtime? What are you prattling?
Huh? Somehow someone swapped out my posts. And put a video from another thread into this thread.

Huh?

Watch how far evos try to take their Darweenie fantasies.

Why are fossil thumpers relying so much on speculationism and drawings?

No science?

When evolving from a cold-blooded reptile to a warm-blooded bird, in the intermediate stage was it a lukewarm-blooded repbird?

Lukewarmism.

Catfish is a fish mammal "transitional".

With few exceptions, birds have light weight hollow bones. Snakes and dinos are not payload sensitive.

The flow-through lung is unique to birds. The fossil thumpers have no pulmonary systems to observe from once upon a time far faraway long longago.

In the Bible, the false god Dagon was half man and half fishie.

No.
It was a line of warm blooded theropod dinosaurs, stretching back to the Trasic period, and to the warm blooded proto-saurians of the Permian.

Did you use a time machine and a rectal thermometer to take his body temperature? Inserting glass into the rectum of a dinosaur sounds dangerous. I'm impressed.

Sorry, I just assumed you had empirical evidence to support your claim that "it was a line of warm blooded theropod dinosaur..."
And you assumed correctly, for a change.
But then you went full moron, and decided that a time machine and a rectal thermometer was the only way to determine if theropod dinosaurs were endothermic.
Ignoring all the REALISTIC methods available, in favour of the most bizzare and UNrealistic method you could imagine.
We know that endothermy was prevalent among permian proto-mammals, and proto-saurians, because of how bones grow in animals with endothermic metabolisms.
The distinctive growth patterns that are the hallmark of endothermy.
 
Done.
No. Nobody took the temperature, but by STUDYING THE BONES, they could determine that NON-reptiles were endothermic (warm blooded).
So the bones never cooled down after all those years? Lol.

And dinosaurs are reptiles which are cod-blooded. Surprised you didn't know that.
