Dinosaur RBT -- Birds and T. Rex

Looks like there was some soft tissue (collagen) in a T. Rex bone viable enough to be tested for it's DNA sequencing. The Article I first found this out from is scant, and I don't have time to get deeper into it right now, but this is a big deal. It was thought impossible to have soft tissue survive and be testable over such great stretches of time.

One of the major revelations was a distinct genetic similarity to modern-day birds, which formerly was attributed only to physiological traits that could be seen in fossils. Big news, because DNA similarity takes the hypothesis that birds evolved from dinosaurs to a whole new level of veracity.

I almost didn't check out the story, because as a biologist, you get tired of stories on T. Rex, and Great Whites, etc. The show-stopper, TV-crowd type of subjects. Glad I did though.

If more interesting info is revealed I'll revisit this, but I have a Chem assignment due at midnight which I haven't started yet, and I still sport a Tubercular cough bad enough to scare grandmothers at 200 paces, so I expect it's going to take me a while to finish.

Of course dinosaurs are evolved from birds. That's why they drop feathers in WoW,

You're just sneaky that way Tate LOL.

Shocho, why hadn't I thought of that. Wonder how the necklaces they wear work into the whole theory. That's kind of tool-making in my book eh? LOL.
