Jurassic Park! At a chicken farm near you!

I like dinosaurs. I'm pretty sure most people know that.
I'm watching "Dinosaurs" on Discovery right now, and they're examining the DNA of modern birds. Currently, it is thought that birds are the descendants of dinosaurs, specifically the therapods like Velociraptor.
If birds are the closest relative to dinosaurs, they would have a lot of dinosaur DNA in them. (Take that, Michael Crichton!). The genes were modified and changed, some were shut down. By changing these genes back, and activating the original genes, we could theoretically create a proto-dinosaur.
An example shown is the tail. The tail in birds would grow indefinitely but there is a protein that inhibits that. By shutting off this protein, the tail will grow to the proper length. This was already performed in experiments. Ditto for chickens with teeth. They didn't add genes, they didn't mix up DNA with other animals. They simply changed the timing and the genes did the work themselves.

Is building a dinosaur possible today? No. Near future? No. Is it ethical? Probably not.

Cool? Heck, yes!

Now Randall really has something to worry about.
