That Jurassic Park article really doesn't address whether the stuff that happens in Jurassic Park could happen.

It addresses whether or not buried bones could store DNA and rightly points out that buried DNA breaks down over time and that there wouldn't be enough left in buried bones.

But, that's not what happens in Jurassic Park. In both the film and the movie the DNA doesn't come from buried bones - it comes from material that is trapped in amber, which would slow down the DNA degradation process.

And... the book at least (maybe the movie too, it's been too long for me to remember) addresses the degradation of DNA. They are not working with full DNA strands because of the degradation, just partials, so the scientist dude guesses at what would be in the missing strands and inserts a combination of avian and reptile DNA from modern animals that could have reasonably been assumed to have evolved from the dinosaur in question.

Also frogs, IIRC.

Gotcha. It's been a while!

Being encased in amber would have to slow down degradation a *lot*, considering how long ago the dinosaurs were.

Getting more and more information out of less and less data is a fascinating trend in modern science, and I wish science fiction would do more with it. The actual DNA is gone, but its doubletalk resonance remains and all you need is a superduperdoubletalk reader.

My impression is that:

* the details of the process as described in Jurassik Park are completely implausible to biologists
* as a reasonably scientifically literate non-biologist, the idea that we might find some way of finding dinosaur DNA seems unlikely, but not rule-out-able
* the idea that chaos theory has anything to do with a dinosaur theme park is complete bullshit

The best suggestion I've seen yet for The Doctor's next companion cartesiandaemon October 12 2012, 11:32:22 UTC
Was that supposed to be a weighed companion cube? Because it should have been! :)

Definitely a cinder block.

RE Doctor Who: That was so Gonzo the Great. Who in my opinion would be the best Doctor companion ever.

RE eyeball GIANT SQUID!!!!

a Muppets/Dr Who crossover would be either the best thing ever, or the best thing ever while killing the Whoian franchise.

in any case, i second Gonzo as companion.

It would at the very least be a wonderful one-off spoof thing. The Muppets and the Doctor; what better combination could there be?
