Apparently, some collagen was found in a T-Rex bone and it allowed scientists to get a protein sequence from it that shows Rex is probably related to birds.

I like this comment because it does show something about the burden of proof and how science takes it very seriously. They're not always right, but they'll work hard to find the truth.

Basically if a scientist claims something extraordinary, then they're going to give you the extraordinary proof. I think to do otherwise would make the scientist in question look really, really stupid. Cold fusion, anyone?

As I commented before: Jurrasic Park, Anyone?

As for cold fusion, no thanks. That is FAR too dangerous for the mindset of man to tinker with. As you proabably know, Cold fusion can theoretically use anything for fuel, including this planet and everything on it. I think we need to calm the planet down a bit before we start playing with that stuff again.
Notice you have never ever heard from those 2 guys who claimed to have invented cold fusion? Ever? ; )
