Rats & Humans' genome is 99% the same

Rememer:

Moving on: The thing about being able to manipulate our genes... Has anyone noticed that when new technology arises it almost always gets used in ways no one would've thought? And sometimes even more quickly than anyone would've thought, either? 15 years ago, even 10, who'd've thougth we be paying bills, renting movies, and/or generally conducting our lives over the net? Remember, 10 years ago we were still on 486's using the Information Super Highway (I still shudder when I hear that term, so I apologize to everyone for using it)

Sure, it's hard to concieve of such things now, but my whole point was we don't know what could happen in the future. Yes, NOW the only way to change genes is with an egg, but who knows? Maybe someone will develop nano-machines (i think this has already been mentioned in this thread, too) that can go around switching on all the necessary dna for gills. There's really no limit to human imagination and ingenuity.
