Protein links T. rex to chickens

From the BBC:

Protein extracted from 68 million-year-old T. rex bones has shed new light on the evolutionary link between dinosaurs and birds.
Researchers compared organic molecules preserved in the T. rex fossils with those of living animals, and found they were similar to chicken protein.

If you notice, the BBC have also, quite helpfully(!), published a picture of a T-Rex and a chicken, both looking in the same direction, just in case you didn't know what each animal looked like, and to prove that they look quite similar(???). Thanks for that.

While this may be interesting to the scientists, all this makes me want to do, through millions of years of inherited DNA from my cave-man ancestors, is run up to the nearest chicken, grab hold of its scrawny neck and shout:

"Not so f***ing big now, are you. Go on, bite my head off now you b*****d!!"
