    Minus the bickering crap making it about political party, it IS an interesting vid. Too bad it got smooshed with the hate.

    Jurassic Park style cloning couldn't work in real life because over millions of years, a planet's atmosphere is always gradually, naturally changing in chemistry. So if you cloned something that lived half a billion years ago, today's atmosphere would probably kill it. And its immune system would be genetically designed for bacteria species that lived back then, not today's bacteria. So even if today's atmosphere didn't kill it, today's germs surely would.

    It's just incredible to think that these monsters were actually real and that we actually walk in their footsteps. :) I find that fact just amazing!

    The largest animal that ever lived is a living one, the Blue Whale.

    That's certainly true at least in the most recent many millions of years. A blue whale is the only lifeform on this planet which has the physical measurements of an average Boeing jet. Except the whale is probably far heavier.

    Hmm, you're way off the mark, there. While the proportions of the contents of the atnosphere have changed over time, that would not adversely affect those animals anymore than slightly raising or lowering the oxygen content of a room would harm you.

    Secondly, immune systems aren't catered to "existing bacteria". In fact, that's the entire point of an immune system...to deal with new, emerging threats. Every cold you catch is the first time you have ever encountered that specific virus.

    The real reason that sort of cloning will never work is that we will never find an intact, full or nearly-conplete genome from creatures which existed that long ago. We would also have a very tough time replicating the chemical environment of their gestation/eggs.
