Technically, it's just a matter of having some close relatives and some fossil DNA and then turning off or on some sequences and modifying the eggs.

Personal DNA full sequence scans are in the $9500 range, just had another price drop.

@1 But I've had birds all my life and it's important to understand they have behaviors that are very much tied in to their body structures. A long tail, for example, might make us think it looks more like a dinosaur, but instinctually I don't see that it will be used like one. And if we engineer arms and hands, will they just flap all the time like a bird trying to gain flight?

Which would come first though, the dinosaur or the dinosaur egg?

@2 excellent point, but I wonder if a creature that had these appendages from the beginning of its life would adjust accordingly... or perhaps the genetic switch that creates the appendage might also flip a genetic switch in instinctual behavior?

@4 There is a bird in Florida that still has claws on it's arms. It's behavior is to use both it's claws and it's wings.

Try it and see, what the fuck. At the end of the experiment, you can always fricasee it up for dinner.

@6 for the yummy Four Loko Yoko Ono stirfry win!

Well, Mary, that was supposed to be a surprise for your birthday, but you just had to peek. Now you don't get anything.

@1: "some fossil DNA"
Stopped reading there. If you want me to pay attention to you, please bear in mind that I can't hear you clearly when you've got Jurassic Park's metaphorical cock in your mouth.
