WASHINGTON - It looks like chickens deserve more respect. Scientists are fleshing out the proof that today's broiler-fryer is descended from the mighty Tyrannosaurus rex. And, not a surprise, they confirmed a close relationship between mastodons and elephants.
Fossil studies have long suggested modern birds were descended from T. rex, based in similarities in their skeletons.
Now, bits of protein obtained from connective tissues in a T. rex fossil shows a relationship to birds including chickens and ostriches, according to a report in Friday's edition of the journal Science.
