Perhaps you know of a way to go back in time or speed up the reproduction of organisms?
It's called, "public housing."
I think the original assumption should be a blank hard-drive. Where do you think the simulation will go from there?
What's your point?
If it's extraordinarily difficult to to produce experimental confirmation of evolution, so what?
This artificial petri dish experiment is a joke. I happen to believe that the circumstantial evidence argues strongly that evolution of some sort is at work in speciation. I don't think we've come close to nailing down the mechanism for it.
One could construct artificial petri dishes where, rather than random mutation and natural selection, Lamarckian assumptions drove the virtual speciation, or invisible genetic elves. What would be proven, exactly?
