The bones are hollow, but to claim that hollow bones (and only hollow bones) makes it an avian is an unsupported conclusion (such as the Boston Globe seems to do). Hasn't the creationist intelligent design crowd always complained that science jumps to unsupported conclusions?
But if something has hollow bones, a wishbone, and feathers, and lays eggs, what would you call it?
... And now they've found proteins matching chickens, ... Jim, it's a pretty safe bet that Tyrannosaurus rex (& friends) are related to birds.
Are we talking about bird-like hollowness, or man-like hollowness? Our bones are hollow, at least the long bones (and a couple others), and filled with marrow. But they’re not bird-like.
So how are they different?
(Never mind that was a rhetorical question,...)
Like most of the 5000 species of living mammals, human bone has thick relatively homogeneous walls and are filled with marrow, as you state.
Birds have thin laminar walls and are air-filled.
The bones of T. rex are like the bird pattern, --so much alike that they can determine the sex of the specimen.
I’ve seen a lot of great Discovery and Science Channel shows about dinosaurs, and none of them compared the hollowness of dinosaur’s bones to birds bones.
Maybe they aren't willing to get out onto thin ice ... and just because you haven't seen E. coli doesn't mean it's not there.
--or that you won't get sick from eating contaminated hamburger.
Am I really missing such an interesting similarity?
Apparently.
... I’ve seen documentaries that compare dinos to birds, and never heard this claim before.
I thought you said you haven't seen it before?
... no matter, I think you're going to see more of them now.
protiens “matching” chickens?
” The sequence similarity between the T. rex and the chicken was 58%, while it was only 51% similar to both frogs and newts. This compares with a reported 81% similarity between humans and frogs, and 97% between humans and cows.”
“Moreover, while some of the peptide fragments showed sequence matches to chickens, others matched frog, or newt, or even fish and mice. The authors did point out that not all organisms are in the database. Although the chicken was the closest match from the database, it is possible that animals not included could be a closer match. “

We ‘match’ Banana DNA too- but I dunno bout you, but I don’t think we’re all bananas lol
