This thread is in the Aspiring Writers forum, not Science/Nature; so even if I agreed with your argument (which I don't), it would not colour my response to the question at hand.
The
story idea that we were looking at presupposed the preprogramming of genomes to produce specific (and similar) creatures many (perhaps hundreds) of millions of years in the future on a number of different planets.
- One pro argument stated (if I may condense it a little) that the amount of information held in a genome can be much greater than we currently assume; it could therefore be used to produce the required effect, i.e. intelligent saurians on all of these worlds.
- One counter argument was that the way evolution works and the way it interacts with the environment both act against the kind of predictability required to achieve this outcome in the story. (This argument assumes that intelligence is rare, so that merely creating an "Age of Dinosaurs" on each of these worlds is not enough.)
It is the ability to
guarantee a number of predetermined outcomes that is in dispute in this part of the thread. (Well, I'm disputing it.
)
