And, unfortunately, movies such as Jurassic park have filled the popular culture with views of genetics that were not even up to par when the movies were made.
I cannot remember the context, but I remember reading something along the line a few years back, in which the genetic material that seems to code for an eye in a fly was inserted into Frog DNA.
The result was an additional frog eye on the frog's back.
I may be getting that experiment totally mixed up.
But I remember that the point was that a given result was not directly the result of the genes as much as the effect and/or interpretation of those genes by the proteins and molecules circulating in the host.
That is why I don't think you could ever recreate an extinct animal.
At best, you would get the interpretation of the DNA by the animal it was inserted into.
This was a few years ago, and I have not yet clicked on your link....
Looks like current work is making it more and more clear that a lot of heredity is nothing to do with what genes you have. I recall some time back experiments that showed that what rat parents got taught influenced their offspring's abilities. May help to explain the 3 points rise in IQ values every decade?
