Which came first, the chicken or the T-Rex?
Okay, obviously the T-Rex. But as it turns out, they have much more in common than just a clever blog title. Genetic researchers have just announced that those clucking, egg-producing denizens of the barnyard that we until now thought of as relatively harmless, are actually related -- though rather distantly -- to the T-Rex. By studying proteins from a 68-million-year-old T-Rex bone, they were able to prove a direct link between the two species. Scientists have theorized for years that birds evolved from dinosaurs, but until now, had no tissue-based proof of it.
